Press Release: NASA Awards PADT and Penn State University a $375,000 Phase III STTR Research Grant

Posted on September 29, 2021, by: Eric Miller

When we applied for a NASA Small Business Technology Transfer (STTR) grant with Arizona State University in 2018 we had high hopes around that the idea of developing simulation and manufacturing techniques that would allow engineers to mimic structures found in Nature. Today's win of a rare Phase III grant from NASA exceeded those hopes and further showed the space agencies' interest in the research that PADT, ASU, and now Penn State are engaged in.

Inspired by the research of former PADT engineer and now ASU professor, Dr. Dhruv Bhate, the idea was to take a look at how nature uses repeating structures and responses to loads to optimize structures and to use 3D Printing as a way to create the derived shapes, growing geometry just as nature does. That Phase I was received well and led to a Phase II grant in 2019 to dig specifically into lattice structures. In addition to that work was the development of a topological optimization tool that could look at multiple types of loads and create aperiodic lattice topologies.

Researchers at NASA like those results enough to then grant PADT a Phase III project to further the development of the optimization tool and to connect it to a fluid-thermal optimization tool developed at Penn State under a separate NASA project. The study is called “Thermo-Fluid and Structural Design Optimization for Thermal Management” and it will look at creating structures that are strong, light weight, and have the thermal performance required for difficult launch and space-based missions.

You can read more in the press release below or here: PDF | HTML.

We are exceptionally proud of all three phases of this project because they show:

  1. PADT's ability to work with academia for R&D that results in useful tools
  2. Our deep and broad understanding of simulation across physics
  3. How our unique expertise in Additive Manufacturing can be combined with our simulation knowledge to turn theory into practical hardware.

If you have needs in any of these areas or are just looking for a strong R&D partner that can help make your innovation work, reach out to PADT.

NASA Awards PADT and Penn State University a $375,000 Phase III STTR Research Grant

The Grant is a Continuation of PADT’s Topology Optimization Research, Which Will Fund “Thermo-Fluid and Structural Design Optimization for Thermal Management”

TEMPE, Ariz., September xx, 2021 ─ In a move that acknowledges its excellence and expertise in R&D for numerical simulation and 3D printing, PADT today announced NASA has awarded a $375,000 Phase III Small Business Technology Transfer (STTR) grant for PADT to collaborate with Penn State University. The partners will expand research into thermo-fluid and structural design optimization to provide engineers who design next generation launch and space crafts with better ways to design more robust and efficient structures that experience loading fluids, forces, vibration, and temperatures.

The Phase III STTR grant is a continuation of the original $127,000 Phase I and $755,000 Phase II grants awarded to PADT and ASU’s Ira A. Fulton Schools of Engineering in August 2018 and December 2019 respectively. This is PADT’s 17th STTR/SBIR grant since the company was founded in 1994.

“Furthering our research in simulation and 3D printing for topology optimization and thermal management is critical to the future of aerospace development,” said Alex Grishin, Ph.D., consulting engineer, PADT. “This Phase III award underscores how valuable NASA found the work we did earlier with ASU and signals their desire to have PADT work with other universities to transform it into a tool that engineers can use to design better launch and space-based structures.”

The objective of the joint effort between PADT and Penn State University is to successfully demonstrate the integration of 3D data output from Penn State Mechanical Engineering Experimental and Computational Convection Laboratory’s (ExCCL) thermo-fluid optimization code, developed under a NASA Aeronautics Fellowship grant, into PADT’s topology optimization tool. The latter was developed by PADT under the STTR Phase II contract.

In Phase II, PADT partnered with Arizona State University (ASU) to develop and test a novel shape optimization tool that used a unique methodology for topological optimization, taking both the thermal and stress response of a part into account. 3D printing was also used to create the geometry produced by the optimization approach. Phase III will connect PADT’s tool to Penn State’s tool, which uses genetic algorithms to better handle the optimization found in thermo-fluid problems.

“Taking our tool and connecting it with the optimization capability that Penn State developed has the potential to benefit aerospace design engineers worldwide,” said Tyler Shaw, PhD, PADT’s VP of Engineering and the leader of the group responsible for this work. “This project will take the joint research one step closer to delivering on an optimization approach that, just as in nature, takes into account all loads, regardless of physics.”

The ultimate goal of the project is to continue research with internal and government funding to create a commercial product that engineers can use as an alternate way to optimize the shape of structures that see loading from multiple physics.

Girl Gang Garage Iron Maven Project: Taking Shape, Moving Ahead

Posted on September 21, 2021, by: Pam Waterman

If you’ve been following Girl Gang Garage on LinkedIn or Instagram, you know there’s been a ton of progress on the Iron Maven Volvo-rebuild project since PADT’s last post in July. Back then, most of the work had focused on gutting the 1961 Volvo PV544 body and interior, and PADT was able to capture much of the sheet metal shape and dimensions with its GOM Tscan Hawk 3D scanner. We also started brainstorming various 3D printed parts to enable new component designs produced on Stratasys 3D printers.

Since then, Bogi Lateiner, co-owner of Girl Gang Garage (and TV host of Motortrend’s All Girls Garage and Garage Squad), co-owner Shawnda Williams, and a rotating team of volunteer women have turned their efforts to disassembling the second vehicle: the new 2019 Volvo S60 T8 Polestar Engineered sedan (donated by corporate sponsor Volvo) and merging its chassis with the PV544 body.

Sounds simple, sort of? It might be if it weren’t for the facts that:

  • a) the wheelbase (front-tire center to rear-tire center) of the two cars differs: the PV544 clocks in at 102.5 inches but the S60 is quite a bit longer, at 113 inches.  Also,
  • b) the track width (axle length) differs – this time the PV544 is about 12 inches narrower at the front (51 inches versus 63 inches), which means the Girl Gang team needs to expand both of the front fenders by half that amount to accommodate everything in the engine compartment. And, lastly and conversely,
  • c) the S60 dashboard is so wide that it needs to be reconfigured from 56 inches down to about 50 inches or less, to fit the interior dimensions.

Growing Fenders, Redesigning a Grill

But with the track-width difference between this design and that of the new Volvo S60 chassis, the Girl Gang Garage team needs to splice in about twelve more inches, probably incorporated in the fenders.

(Image courtesy PADT Inc.)

The old-school approach to reconstructing the front bumper-grill section and fenders would involve cutting the original sheet metal, shaping new metal splices by eye and tape-measure, and welding everything together with skilled handwork. This time, although the first and last steps still apply, that project becomes a much more precise, and predictable, task thanks to the digital workflow of 3D scanning -> data processing -> CAD design. These steps are now underway and will set the stage for a cool new grill and fenders that will act big but fool the eye just a bit to keep the overall lines intact.

It’s pretty clear that this front-end has seen better days, so the analysis and measurements of the existing surface needed to be carefully analyzed. Donated expertise for this task came from Chris Strong and Hayati Dirim of Rapid Scan 3D, who mapped the scanned mesh onto planes and surfaces that define the current grill-mount opening.

This information has been handed off to the CAD support team. Working hand-in-hand with the Girl Gang Garage experts, the team is using Fusion 360 CAD software, donated from Iron Maven sponsor Autodesk, to analyze these defining surfaces and design a new grill in CAD, which we expect will be 3D printed and painted to match the updated (not yet announced) body color from sponsor BASF.

Knowing both the fender and grill/frame exact dimensions also supports the team in defining the connections and shape of the widened fenders.

Critical surfaces and dimensions extracted from the bumper/grill scan, converted into CAD and brought into Autodesk Fusion 360. The four planes define the current limits of the opening for the grill. This information will guide the CAD-layout of the brand-new grill design and also serve as boundary layers that mate up to the expanded fenders. (Image courtesy PADT Inc.)

The brand-new 2019 Volvo S60 T8 Polestar Engineered sedan was almost too cool to cut up – but Girl Gang Garage knew that something even better would emerge in the end. Before the roof was cut off (see the video on LinkedIn), the work timeline required removing the dashboard with all its electronic components.

Here’s the extracted S60 dashboard, viewed from the bottom and front:

And the frame behind it:

And here are the existing red PV544 dash and the black S60 version side by side (the dots are the reflective targets used with the 3D laser scanner). The S60 configuration needs to fit in the original PV544 space. To compress this at least five inches, the glove-box probably has to go.

Once again, the team is turning to scan data, and that analysis is in process.

Stay Tuned

Due to the scheduling and travel challenges presented by the ever-shifting COVID scene, Girl Gang Garage has decided to complete the Iron Maven for presentation at the 2022 SEMA Show (highlighting automotive specialty products). This also allows more time for 3D printing the new components which are coming off the Stratasys F370 printer. PADT will be documenting updates and sharing cool photos of this one-of-a-kind project in the months to come.

An Ansys Licensing Tip – ANSYSLMD_LICENSE_FILE

Posted on July 15, 2021, by: Josh Stout

Most Ansys users make use of floating licensing setups, and I would say the majority of those actually make use of licenses that are hosted nonlocally but on their network. Within this licensing scheme, there are quite a few different tools and utilities that we can use to specify where we pull our licenses, too. One of the methods that is making a comeback (in my recent experience) as far as success in troubleshooting and overall reliability is specifying the environment variable ANSYSLMD_LICENSE_FILE.

This variable allows you to point directly towards one or more license servers using a port@address definition for the FlexNet port. With just this defined, the interconnect port will default to 2325, but if your server setup requires another interconnect port then you can also specify this using the ANSYSLI_SERVERS environment variable with the same format.

The downside is that this is a completely separate license server specification from the typical ansyslmd.ini approach, so any values specified this way will not be visible in the “Ansys Client License Settings” utility. On the upside, this is a completely separate license server specification! Meaning, if there are permission issues associated with ansyslmd.ini, or the other license utilities experienced some unknown errors on installation, this may be able to circumvent those issues entirely.

Also, for more advanced setups this can be used to assign specific license servers to individual users on a machine or to potentially help with controlling the priority of license access if multiple license servers are present. Anyway, this may be worth looking into if you encounter issues with client-side licensing!

A PADT Engineer in King Attiball’s Court – Chapter 4

Posted on May 17, 2021, by: Eric Miller


Chapter 4
Off to Sea

Ash could not believe what she was seeing. Somehow her phone was getting a signal, and she was able to text with Alex.  After starting to text him, she realized talking would be much faster. So she clicked on his name at the top of the screen and then the telephone icon.  A message popped up informing her that there was no voice service.

She said, "then I guess we will text," to herself and began to type with her thumbs.

ASH: "I know this will sound strange. "

ASH: "But I woke up in ancient Phonecia."

ALEX A: "You mean at that camp you were going to? The cops said you never showed up."

ASH: "No.  I mean ancient Phonecia.  Somehow your augmented reality contraption shifted me back in time!!!"

ALEX A: "That makes no sense.  I know that room had some wacky fancy sensors and emitters that projected directly into your visual and audio nerves. But time travel ?!?!!?!?!"

ASH: "Well, they projected me right back into the past."

ALEX A: "I need to check something. Hold please"

ASH: "I have millennia or three.  No hurry."

ALEX A: "Well… hmmm… I looked at the log file.  You told the system to start your job at 2022 BC and gave phoenicia as the server name.  The feedback from the job controller said:"

ALEX A: "Batch Job Submitted.  Engaging Quantum Temporal Solver."

ASH: "What is a quantum temporal solver?"

ALEX A: "Well, there is a quantum computing project in the back of the basement. Some government project.  They paid for the AR interface you were using. It's connected to the compute cluster too."

ASH: "What does that have to do with time travel."

Alex A: "Hmm… It's all classified. But I wonder…"

Ash started to type "I wonder what" when her screen went dark, replaced by an empty battery icon. She looked at the moon outside her window. So bright and clear in the sky, and she yelled a four-letter word that would not exist for four-thousand years.

Moments later, Takaa burst into her room and asked, "My lady, are you safe?" while he scanned the room, spear in hand.

Verihbitt and then Mnihh'dm soon followed. The room was suddenly crowded.

Ash took a deep breath, looked at her now blank phone, and said, "I'm fine. I had a bad dream. I must have yelled in my sleep."

Verihbitt looked at Ash. "I can hear the fear and frustration in your voice." She then walked to Ash and enveloped her in her arms. The unexpected empathy broke Ash, and she began to sob in her new friend's arms. 

That night, Ash slept well.  When a servant came into her small room and woke her, the sun was already high in the sky.

"My lady, I have been asked by the Princess to bathe and dress you."

Ash sat up in the bed while a half dozen girls and women streamed in with pots of steaming water, containers of oil, and piles of clothes.  Before she could say no, they pulled her to her feet and removed the robe she had been wearing.

Ash said, "be careful. I made that myself…"

One of the older serving women looked at the robe then at Ash, and said, "My lady should leave the sewing to her slaves." She then casually tossed the robes onto the brazier burning in the corner of the room.

Ash's protests were stifled as more women lead her to a couch and began to smear scented olive oil over her body.  She was not used to be naked in front of a group of women. She had always avoided PE classes for that very reason.  However, she hat to admit it felt excellent.

When they started to scrape the oil from her skin with long bronze scrapers, she relaxed and said, in English, "When in Phoenicia."

Over an hour later, she exited into the courtyard dressed in flowing red and brown robes, her hair stacked upon her head with bone pins and a heavy, blue lapis lazuli necklace around her neck. She had to admit to herself, she felt pretty good.

A servant guided her across the courtyard into a larger room where her friends, the King, and other court members sat or lounged on couches arranged in a circle.  Verihbitt's father was there lying next to Verihbitt. His exposed legs were bruised and scraped. When he saw Ash, he smiled and moved to get up.  

"Father, no. You stay where you are.  She can come to you," Verhibitt said as she stood and greeted Ash with a hug.  She then looked Ash up and down at arm's length and said, "You look much more presentable."

Another servant appeared out of nowhere and lead Ash to an empty couch and put a table covered in food in front of her.  When the smell of the fresh fruit hit her, Ash suddenly felt very hungry.

Ash was able to devour a pile of grapes before King Attiball sat up upon his couch and addressed the group. "Now that we are all here, I must ask more of all of you."

Everyone stopped eating and chatting and gave the King their attention.

"A trader just returned from the western end of the sea with bad news.  Two of our colonies west of Carthage have been sacked and burned to the ground. I will not and can not stand for this."

A large man dressed in armor stood up and said, "I will prepare an army. We can sail on the full moon."

"General, as much as I would like to strike out with our might, right now we don't know where to strike. This was not the act of another prince. Nor was it the local slaves revolting.  The cities are gone.  There is no sign of an army or a rabble hiding nearby. You will get your time, and you should prepare the men and provisions and position them in Carthage. But, before we can strike, we must know who to strike."

The King walked to Verihbitt's couch and said, "Princess Verihbitt, I need you to go on a voyage. I am asking you to take whoever you need and join the trader on his return to the west. This will be a dangerous journey. But I fear staying here may be just as dangerous."

Pacing back to the center of the room, the King continued. "We tortured the men who cut the ropes yesterday.  They would not say much before they died, but we discovered that they came from the far west, where our sea opens up to the endless sea. When they cried out in pain, they called to someone name Gula, and they called him the Master of Atlas. I don't know if it is a western god or a Prince."

Verhibitt kneeled before her uncle. "My King," she said, "we will go west, and we will send word back on what we find. "

Soon after the King left, Verhibitt, Mnihh'dm, and Takaa huddled with Verhibitt's father.  Ash tried to stay out of the discussion, but she soon found herself drawn in.  After they had planned their route to Egypt, Carthage, and then further west to what Ash assumed was the coast of Spain, she could no longer contain herself.

She asked Verhibitt, "I know you just met me, and I am a stranger here, but I would be honored if I could travel with you. I have never been to Egypt or Carthage, and I do think I might be helpful, even though I don't know how to fight or spy."

Verhibitt smiled and made a sound that Ash assumed was the ancient Phoenician equivalent of "Duh."

An hour later, Ash and her companions were back on a chariot headed to the city. They were also accompanied by four war chariots with a driver and archer in each. The trip was uneventful and they went directly from the city gate to the port, stopping in front of a ship. It had a single mast in the center and a huge wooden rudder at the rear.  Ash could see rows of benches for oarsman. A carved figure of a woman with elaborately styled hair decorated the bow.

There was not much for Ash to do in the chaos of loading a ship for a long voyage. After noticing her standing on the pier, Mnihh'dm took her to a pile of cedar timbers piled next to the ship. She climbed up and sat on top of the pile to get a better view. The process was fascinating. A steady stream of people arrived with clay pots and woven baskets.  They moved in a coordinated way with no direction, doubtlessly having each done it hundreds of times before.

Over time her thoughts also turned to her phone. She started by pondering the physics of being able to communicate with the future. Then her mind turned to problem-solving.  She needed a way to recharge the device. Every idea she had seemed to be a non-starter.  She even thought about the potato battery she had made in elementary school. Then she remembered that potatoes came from South America.

Her reverie was interrupted by a loud crashing sound behind her.  She stood and turned around.  There she saw that a cart full of clay pots had run into a cart full of some sort of citrus fruit.  That reminded her of a project she had started during a LARP'ing week a few years ago. She and another engineer in the the group had made a Babylon Battery from a clay pot with an iron rod, a copper tube, and some orange juice.

She pivoted towards the ship, spotted Mnihh'dm, and yelled as loud as she could, "Friend!  I need your help!"

Sword drawn, Mnihh'dm rushed towards Ash. 

"No, I'm not in danger. I just need your help. I need to make something for our journey.  I can't explain what it is, but it is very important to me. Can you lend me someone that knows the markets here?  I need supplies. And coin?"

Mnihh'dm relaxed. "Yes, my Lady.  And some soldiers to watch over you." By the time Ash lowered herself off the stack of cedar logs, Mnihh'dm had returned with two soldiers and an older woman.

"These three will help you." He then handed Ash a heavy leather bag, "And you will need this to pay for your supplies. But, please be careful. Do not do anything that might attract the attention of our brilliant magistrate."

An hour later, Ash and her three helpers returned with baskets full of her supplies. Finding the copper sheeting and wire had been the hardest part. When they were about to give up their quest, they had found a jeweler who had both.

She led her group onto the ship and had them deposit their findings in a pile against the mast. 

Phoenician ships did not have cabins or a hold.  Cargo and supplies were piled between the rowers, and passengers could travel in tents erected on small decks at the front and back of the ship. Ash knew that they would row or, if the wind was favorable, sail during the day. They would have to pull onto shore at night to camp. Looking at the cramped area around her, she realized that the next few weeks would be long and difficult.  Working on her battery would help pass the time.

Her supplies safely secured, she thanked her helpers, then moved to the front of the ship where Verihbitt stood with some men she did not know.

Verihbitt said, "Ash, I am glad you are back. We are loaded and about to leave. And I would like you to meet our captain, guide, and owner of this fine vessel, Duzi."

He was a tall man with a mane of long, flowing brown hair tied with a simple leather thong behind his head.  Ash could not help but notice that he wore a short, sleeveless tunic that showed off his muscular build.

Bowing slightly towards Ash, he said, "Princess, you mentioned that you would be bringing a foreign girl with you, but you did not mention that she was so beautiful." And then he smiled at her.

Ash felt her face flush. She managed to say, "Thank you, um, we are pleased you could help us, on, um, our journey." All she could do was look at her own feet.

Verihbitt laughed and gently grasped Ash's arm, then whispered in her ear, "Careful, this one could sell eggs to a chicken farmer."

The awkward moment was broken by an older man standing next to Duzi. "Since no one will introduce me, I shall do it myself. I am called Alim by this shark, although I have better names that are too long for his silly brain to remember."

Duzi laughed and said, "My apologies, teacher. Indeed, this is Alim, and he is responsible for my silly brain. My father purchased him in Egypt to be my tutor when I was still a boy. Ignore his complaints. He wanted me to be a scribe, bent over clay tablets all day to count the corn as it goes in and out of a warehouse. He finds my current profession beneath him. And therefore beneath me. One of those long Egyptian names translates to angry old man."

"Ignore most of what he says," said Alim, "He was dropped on his head before he was given to my care, and I have not been able to do much with him. More importantly, the Princess tells us that you are a scholar yourself and a builder of tools?"

Ash felt an immediate connection with this older man that reminded her of so many of her favorite professors. "It is a pleasure to meet you," she said. "I am not so much of a scholar, but I do enjoy making things."

Duzi, playfully pushed the old man behind him. "We have a long journey before us, and you two will have plenty of time to discuss the stars or casting metal or whatever it is that interests this crazy old man.  However, that will have to wait."  

He bowed to Verhibitt and Ash and said, "Everyone and everything seems to be on board. The tide has just started to head out.  If you will excuse me, it is time for us begin." He reached down and untied a rope holding the front of the ship to the dock, signaling someone to do the same at the rear.

Then, In a loud, clear voice, Duzi gave the order to the oarsmen, "Off to sea."

Ash felt the ship rock gently under her as the oarsmen bent to the task, and the ship left the port.

Ansys Mechanical Selection Information: Even More Useful Than We Thought

Posted on May 5, 2021, by: Joe Woodward

I have always known that the Selection Information window is extremely useful, giving us properties like Surface Area, Edge length, and the distance between two selected nodes.

But it will also do a few things that I had not known about, until recently. 

Normally you can Export the Nodal Locations with a solution result plot, but for that you have to solve the model first. If you have not yet solved the model, you can still get the nodal locations using the Selection Information window, though it is a little finicky.

  1. Open the Selection information window from the Home tab.
  1. Select all the nodes by selecting one node and hitting CTRL-A.
  1. In the Selection Information window, click the ‘Node ID’ header to sort by Node ID number.
  1. Select the first cell of the data you want.
  1. Scroll all the way to the bottom of the Window, and while holding down the Shift key, select the last row of the adjacent columns that you want to select.
  1. Once selected, right-click on it and hit “Export Text File”, or “Copy” and then Paste the data into Excel.

The trick is that the “Export Text File” and “Copy” do not show up if you pick the headers to select the entire columns like you do in Excel.

You can do the same thing to thing to get the mass properties of an assembly.

Selecting bodies will give you the mass, centroid, and principal moments of inertia. You can get this in the Worksheet view when the Geometry branch is highlighted.  Unlike the Worksheet, however, we can change the options to show the Moments of inertia about a given coordinate system.

We can now export out the six moments of inertia about any given coordinate system.  Next, I will attempt the find the ACT calls to do the same thing.   Stay tuned…

Project Management for Non-Linear Dynamics Simulation with ANSYS LS-DYNA

Posted on April 22, 2021, by: Eric Miller

We spend a lot of time writing articles about how to use the very capable tools that are available from Ansys, Inc., but tend to skip over the project management side of simulation. But, project management can be as important, especially for challenging simulations, as the technical aspects.  We recently completed a series of Non-Linear Dynamics simulations with ANSYS LS-DYNA and ended up learning a lesson or two about how to get such projects done on time and on budget.

What is Non-Linear Dynamics Simulation, and what makes it different?

When materials are deformed so fast that the rate of strain changes material properties, we refer to that as non-linear dynamics. In non-linear structural simulation, the material may be distorting in a non-linear way (usually plasticity), but the non-linear properties are dynamic. Because of this, time gets involved in the equation, as do non-linear material properties.  Think car crash, metal forming, drop, bird impact on windshields and jet engine blades, and bullets going through stuff. 

There are various software tools in the Ansys family that can do the non-linear dynamics, but our preferred program is Ansys LS-Dyna.  It is an explicit dynamics solver that solves structural, fluid, thermal, and other physics.  It is an amazing program that does many things. Still, for the class of problem we are talking about here, we only care about time-dependent material non-linearity for structural deformation.

Setting expectations

Before beginning a project of any type, it is important to establish goals.  Non-linear dynamics is no different. What is different is that you have to be realistic about what goals you can achieve.  The events you are modeling are, by their very nature are very, well, non-linear. The answers you calculate can change drastically with mesh, loads, material properties, and solver parameters.

If you need high accuracy, then you need to set the expectation that it will take longer to solve, and you have to be more careful with your model. If you don’t need accuracy and you may be looking for relative improvements, like seeing if one geometry option makes things better or worse in your design, then you can back off and be less detailed.  This difference can have a large impact on your schedule and overall cost.

So before you plan, before you start gathering information, decide what you expect to get out of your model.

Planning for the Job

Once you have set your expectations and goals, it’s time to map out the project. It is not that different from most structural or vibration jobs. You still have to get geometry, create a mesh, define loads and constraints, apply material models, run, and post processes.

However, each of those steps can be different for non-linear dynamics.  Here are some critical issues to be aware of when producing a schedule:

  • Geometry
    If you are working with thin, especially sheet metal, parts, you probably want to use shells. They are more efficient and can be more accurate in many situations. You need to not just have a CAD model, but also a model that has the mid-plane surface defined as well as thicknesses.

    You also want to look at removing tiny features that don’t impact the solution.  The run time in an explicit dynamic solver is driven by the smallest element size. If you have tiny features relative to your overall geometry, capturing them can drive up your run times.  So set aside time to remove or simplify them.
  • Meshing
    As mentioned above, small elements can drive up run time. Also, distorted elements or elements that become distorted can cause your solutions to diverge and fail. You may (probably) need to create a hexahedral (brick) mesh.  All of these things require more time to create the mesh, and from a project standpoint, you need to plan for that.
  • Contact
    Ansys LS-Dyan rocks at contact.  It is pretty much automatic in most cases. So here, you don’t have to set aside time to define and tweak your contacts to get convergence. But there are many options, including erosion and other fancy options. Understand your contact needs and track and manage them.
  • Loads
    Everything in LS-DYNA is time-dependent, and loads are no exception.  If you are lucky, your load or loads are constant over time. But if not, you need to set aside time to characterize those loads and get them specified in the right format.  In addition, loads can be calculated, say the results of an explosion or an airbag deployment. These use Equation of State models to calculate forces on the fly and are a major advantage of the tool.
  • Solving
    From a project management standpoint, it is very important to plan for relatively long solves, restarts, and if possible, solving several jobs at the same time.  Non-linear dynamics is computationally intense. Do some trade studies on computer resources vs. schedule time.  Is it worth investing in more cores to solve faster or just let it chug away on a smaller computer? Also, don’t assume a single run to get the answer you want. Often you need to run the model multiple times before you understand what is really going on.

  • Post-processing
    We are solving highly non-linear events, and understanding what the model is telling us is the whole point of the exercise.  Budget time for processing massive amounts of data over time and reducing it into something useful. Also, time is needed to create animations.  The analyst may also find themselves buried in the weeds at the post-processing stage, and project management should take on the role of reviewing the results from a big picture perspective and drive what tables, graphs, plots, and animations are created.

Keeping the project on the rails when things are literally blowing up and crashing

The dynamic nature of both the events being modeled and the process of creating and running the models make for a less predictable progression for the project.  A project manager needs to pay close attention to what is going on at all times and pull the engineers doing the work back up for air to find out where things are going. 

Here are some things to watch out for:

  • Building a model that is more complex than needed
  • Making sure that the situation being simulated in the model is what the customer needs simulated
  • Too much time being spent to fit the model on a limited computer. Get a bigger computer.
  • The simulation engineer is fixated on details that don’t impact the solution much
  • Oversimplification of components, connections, and loads.
  • Science project mode – spending time trying to learn basic information or trying to get something new to work, and not solving a specific problem.

One of, if not the most important roles for the project manager is communication.  Constantly interacting with the engineers (without nagging) and with the customer (the person who will consume the results) is critical.  This is not a throw-it-over-the-wall type of project.  And the more you accomplish, often the more you have new questions.  It may take two weeks or nine months. But either way, the PM needs to be constantly talking to everyone involved.

And yes, here at PADT, we have actually modeled a train car going off the rails. The project, though, stayed on track because we kept a close watch and stayed focus on the specifications. Things did surprise us, and we had to change some of the model when we got the first results, but we planned for that, communicated with the customer, and kept our changes to what was needed to answer the customer’s questions.

Our cars have incredible crash safety, very few planes fail because of bird ingestion, and we create amazing components out of formed sheet metal because of this type of non-linear dynamic simulation, and in most cases, Ansys LS-Dyna. Proper project management that recognizes the challenges and differences for this type of project can make a massive variety of products even better.

A PADT Engineer in King Attiball’s Court – Chapter 3

Posted on April 14, 2021, by: Eric Miller


Chapter 3
Like an Owl

It was comforting for Ash to learn that food tastes had not changed so much over the millennia. Sitting in that courtyard under those trees, the marinated vegetables and stewed meats in the bowls Mnihh'dm had brought out tasted wonderful.  And the bowls of watered wine quenched her thirst and had just enough flavor to taste good and alcohol to kill the microbes living in the local water supply.

Verihbitt explained each dish and sampled them with Ash.

She then drained her bowl of wine and reached over to touch Ash's leg. "You have eaten and drunk. Are you ready for questions?"

Ash was ready. "Sure, I guess now is as good a time as any."

"Are you a witch?"

She was a little stunned by the question but had to remember that everything about Ash's world was magic to this woman. It was best to address that head-on. How do you explain to an ancient Babylonian what an engineer is? She gave it a try.

 "No, I am not a witch. But I am a scholar and an artisan. I study the world around us, and I use what I learn to make things that make life better. Tools that people use."

Verihbitt thought for a while. "Like the King's architect?"

“In a way." Ash pushed down some of the jokes about civil engineers that she had learned in college. "I get paid to solve problems but not to build structures." She could not resist. "Nor do I design ditches."

"It is normal for a woman to do such things where you are from?"

Ash laughed, remembering all the meetings where she was the only woman in the room. "Not as normal as it should be. But it is getting better."

"Well, here it is good for a smart woman like yourself to speak through a man. Some will listen to a wo-"

The sound of shattering wood interrupted Verihbitt as the gate to the courtyard exploded and rained splinters down on the two women. It was quickly followed by the angry shouts of three men who rushed through the opening, spears in their hands. They stopped momentarily to scan the courtyard, then rushed towards Verihbitt.

Without thinking, Ash stood and kicked the low table, bowls and all, towards the approaching men. It slowed them down enough to give Verihbitt time to dart behind the nearest tree.  She reappeared with her own spear, and in one fluid motion,  launched it at the closest attacker.

Another spear flew by Ash's head before it thudded into the chest of another attacker. She looked back as Takaa, who must have been sitting in the far corner of the courtyard behind a thick pillar, grabbed another spear. He sent it past her ear, and she heard another thunk as it landed.  She ran towards Takaa and dived behind the column.

"Fight or flight," she said between gasping breaths. "I guess flight wins out today."

The sounds of a struggle grew louder. There were grunts and cries of pain, but no screaming. After only a few seconds, the sound stopped, and she heard heavy boots approaching her.

"Are you harmed, my lady?" It was the voice of Takaa. Ash relaxed.

Ash stood and came out from behind the column. "I am just a little shaken. I didn't help much."

Verihbitt appeared behind Takaa and said, "Well, we know you are not a witch. You cast no spells. But kicking the table at them did slow them down.  Thank you."

Minihh'dm came flying through the door into the house, short sword at the ready.

"My princess, Verihbitt, you are covered in blood. Are you injured?"

Stunned, Ash looked at Verihbitt and could only say, "Well, I may not be a witch, but you appear to be a princess?"

The next half hour was another blur of activity. Takaa ran outside and returned a few minutes later with a chariot let by a beautiful gray horse. All four of them clambered on, and Takaa steered them down a maze of narrow passages, knocking over stalls and more than a few people who could not get out of the way fast enough. At some point, Ash had to close her eyes and hold on as hard as she could to the two-wheeled cart's railing.

She opened her eyes when Verihbitt told her that they had exited through the eastern gate. Farmland stretched out along the rolling hills. There was still some dodging around donkey carts, and it was too loud to talk. Which was good. Ash needed the journey to process all that had happened. She had never seen someone killed before.  And certainly never with a spear.

Takaa guided the cart off the main road up a dirt track that led up a small mountain. A large stone building stood on top. Mnihh'dm yelled over the din into her ear, "The King's summer palace. We will be safe here. And no, to answer your next question, your hostess is not the King's daughter, but she is his niece."

Ash did not know what to expect as the chariot passed through the gate to the building. The outside was simple stone, and she had only seen artist's guesses at what a Babylonian summer palace would look like.

The bright colors were stunning. There were statues and frescos everywhere. What Ash had seen in books and online was not even close to what she saw in front of her. The large courtyard was surrounded by two stories of buildings. And every surface she could see was covered with paintings or sculptures.

Ash got off the chariot when it stopped, and she was thankful for Verihbitt's steadying hand.

She said, "that was some ride. I was not sure I would be able to hold on much longer."

Verhibitt laughed. "In my line of work, you often have to make a quick escape on a chariot."

"As a princess? I always thought that involved sitting on pillows and being fed by servants."

"No." Verhibitt looked at Ash sideways, smiled, said, "I am also a spy," and ran across the courtyard towards a man in bright robes.

Ash looked more closely at the far side of the courtyard as she walked towards it. The man stood with Verhibitt at the bottom of a large dirt ramp, and hundreds of shirtless men were pulling a stone slab up the ramp on large wooden rollers using two ropes. She could tell there was a carving of some kind of the top surface of the slab. The wall was covered with scaffolding, and it looked like they were going to hoist a giant stone carving up onto the top of the second story.

Verhibitt was waiting for her at the foot of the ramp, her right arm entwined with that of the older man in bright robes.

"This is my father, Prince Batnoam. One of the King's brothers and, more importantly, the King's Architect. He is one of those people who build walls and ditches."

Feeling a little embarrassed, Ash bowed to Batnoam.

The prince nodded his head in acknowledgment and said, "welcome, my child. My darling Verhi has been breathlessly telling me about your adventures today. I have to admit I could not follow half of it, so I want to know more at dinner."

He snapped his fingers, and two women in simple robes appeared as if from nowhere. "Please prepare rooms for my daughter and her friend."

"While we wait for that, let me show you our latest project. This is a piece that shares the story of my glorious brother's latest conquest in the East. It took almost a full year to carve and most of the summer season to bring up the hill on rollers. Today, we will pull it up to the top of the wall and secure it. We will then spend another week digging out the ramp under it to lower it down against the wall."

"And you will spend even more of my money doing so."

Ash turned to see a tall man dressed in shining brass armor taking purposeful steps up the ramp. A dozen soldiers and a cluster of men in robes struggled to climb behind him.

Everyone bowed to him, so Ash followed their motion.

Boatnoam said, "My brother, when you came back from the East you told me you wanted something grand to celebrate your victory. Nobles will flock to the summer palace just to see this story immortalized in stone."

"Yes, yes. That is what you always say. Then you ask for more money, and it is always too late for me to back out."

While listening to the Prince and King jest with one another, Ash looked up at the slab and how they were lifting it. Iron rings were attached to the top of the wall and, ropes went from the slab, through rings, and back down to the teams of men who were pulling. Up next to the rope, she could see two boys were slathering grease onto the rope to reduce friction.

The teams pulled, the King and prince argued, and the boys kept applying grease as the slab slowly moved on the wooden rollers. Ash soaked in the pure joy of seeing ancient engineering at work.

And then, for the third time that day, someone tried to kill Ash.  

Two men who had been walking next to the ropes on either side of the ramp pulled out large axes and, in unison, swung down on the taught rope. With a loud twang, the ropes split, and the slab began to roll down the hill. It headed right towards Ash, her new friends, and the King.

She screamed, "The slab is loose, run!"

She raced to the side as others ran down the ramp in front of the slab. The air was filled with dust, but she could see the stone crash onto the flat courtyard and stop. There were shouts and screams from a large crowd gathered around the slab. Ash ran down the ramp to find Prince Batnoam trapped. A split roller kept the slab from crushing the prince completely, but it was apparent that both of his legs were trapped.

The King screamed for everyone to come out and to fetch new ropes. But Batnoam saw the same thing Ash did. If they pulled the slab in any direction, it would come off the roller and crush him.

"Brother, I think we need to lift it." In between gasps of pain, the architect described his latest scheme. "Put stakes in the dirt mound to keep the slab from moving. Then attach ropes to the far end up through the iron loops. Then pull to tilt it up and off of me."

Ash looked at the geometry. The angle was too low. There was no way they could lift the slab. She decided to speak.

"Your highness, although this idea is close, I do not think it will be enough to lift the stone. In my land, we use a different method to lift large items. Might I try that?"

"No." Said the King. "We will do as my brother's asked, not the musings of a foreign girl."

The next half hour was busy. The workers were able to wedge some more wood under the stone to relieve a little pressure. But no matter how many men or oxen they put on the ropes, they could not lift the stone.

As the sun started to set, Batnoam gestured for the King to come closer. "Brother, it is getting late, and we are losing light. And I do not want to miss dinner." The King laughed at his brother's bravado. "Bring torches and, maybe we should let the foreign girl try."

The King reluctantly nodded towards her, and Ash sprang into action.

"Someone bring that scaffolding over here, the tall one there, and put it over the end of the slab."

She walked to a group of men who had been pulling on the ropes and said, "You need to gather me two of thickest rollers you have. And more rope, lots of rope." She shouted after their retreating backs, "And lots of grease."

It had been years since Ash had studied how a simple tackle worked. But, while others had been attempting to lift the stone, she had been sketching her idea in the dirt. The top roller would be attached to the scaffolding. A rope would be attached to either end of the lower roller, looped up over the top roller, back down around the bottom roller, then over the top roller again. This configuration would provide four times the lifting force, minus all the drag from the ropes rubbing on the rollers.

It took close to an hour to build the rig. No one had spoken to Ash while it was being created and they followed her orders with obvious irritation. But, the King had sanctioned this approach, so they worked at it.

When the rig was ready, she had two teams of twelve men at the ends of each rope.

"You need to pull together so that it lifts the same on both sides." She shouted to them. "At first, it will not move much. But it will move. Try now."

Ash put her hands behind her back and crossed her fingers. In English, she whispered, "Freshman statics, don't fail me now,”under her breath.

They pulled, and the scaffolding creaked. And then the ropes began to stretch. The slab didn't move.

"Keep pulling!"

The men just stood and looked at her.

The King shouted, "Pull, you dogs, or I'll toss all of you off the top of that wall."

With the King's orders, they pulled again, and the lower roller began to rise, pulling the slab with it.

"One more pace back!" shouted Ash.

They heaved one more time as one, and the slab lifted again. Other builders quickly placed wood blocks under the slab while a soldier pulled the King's brother from under the stone.

Once clear of the stone they moved him to stretcher.  Batnoam took his daughter’s hand and says, “I do like this new friend. She is wise, like an owl.”

Everyone was focused on the prince and getting him to his rooms, and they stopped paying attention to Ash. So no one noticed when she lost consciousness and crumpled to the stone paving of the courtyard.

“bzzzzzz.” “bzzzzzzzzzz.” “bzzzzzz”

Ash wasn't sure if she was dreaming or not. She opened her eyes to a dark room. The full moon was shining through open windows and a light sea breeze filled the room with humid, salty air.

“bzzzzzz.” “bzzzzzzzzzz.” “bzzzzzz”

Sitting up, Ash looked around the room. She was a little light-headed but felt better than she expected. The moonlight illuminated her backpack in the corner of the small room. She walked towards it, and the buzzing got louder. It was her phone.

Fumbling a bit, she found it in the outside pocket.

“bzzzzzz.” “bzzzzzzzzzz.” “bzzzzzz”

She turned it over in her hand and pressed the action button. The screen lit the room, showing her a single text message.

ALEX A: "Where did you go? One second you were here. Then you were gone. The system has locked me out. I thought you had gone on your vacation, but the police came looking for you just now. Are you OK?"

At first, Ash thought this must be a message that he had sent right after she had been tossed back into time. She checked the time. It said 5 min ago. The signal strength in the upper right corner showed one bar.

She quickly typed a message.

ASH: "I'm here. OK, all things considered. Let me know if you get this."

She waited for a second, bathed in the moonlight that shined through an open window of a Babylonian King's summer palace.

Good Times and Bad Times – 2020 has been a year to remember.

Posted on December 8, 2020, by: Eric Miller

Here we are, the second week of December in the year 2020. This is the time of year when we usually look back on the year and see what went right and what didn't. In a normal year, it's a fun exercise. You can conduct the review two ways, something like a global pandemic that completely disrupts supply chains, decimated key industries, disrupts how we do our jobs, eliminates almost all travel, and brings real death and injury to people we know and care about. The first is focusing on the negatives, and the second is to acknowledge the challenges and then point out the bright spots. Let's go with that second option.

Responding to the Challenge

We got wind of what was coming early. One of PADT's owners was visiting Taiwan when it started to spread in China. He saw how seriously the Taiwanese government was taking it and let us know. At first, it didn't impact business, but as the global supply chain started to show weakness, our customers started to let us know that they needed to make changes. As working from home became more common, our team helped where we could to get their users set up for Ansys usage at home. We moved meetings to online, and we helped users do their own 3D Printer repair over the phone when we couldn't enter their facilities.

New ways of using 3D Printing & Simulation

As a longtime leader in 3D Printing, a big part of our adaption was to lend our connections and machines to the effort to use additive manufacturing to get protective equipment into the hands of those who needed them. By the time the supply chain was back working, we had manufactured thousands of face masks, consulted with dozens of people seeking our advice, and helped get material into the hands of those who needed it.

We also established a couple of panels on how our customers stepped up with both 3D Printing and Simulation to battle the virus's spread. Take a listen to the recordings to learn more about some very clever applications of these two key technologies.

Even nine months into this pandemic, we are working with several companies on products or processes related to dealing with the virus.

New ways of doing work

We got a head start on cleaning and social distancing because we saw what was going on in Taiwan, and we started prepping our infrastructure for work from home (WFH). When things started to worsen in the US, our employees stepped up and made the changes they needed.

For us, Microsoft Office365, Teams, and OneDrive have been a wonderful toolset for collaboration and communication. We even got our ancient, over 20-year-old phone system swapped over quickly to forward to cell phones and email. Thanks to our amazing IT team, we were soon meeting with customers and vendors worldwide, collaborating, and pretty much back on track.

Essential employees adjusted their schedules to reduce the potential of contamination, and we doubled-downed on social distancing. All the machines kept running, our IT infrastructure stayed solid, and we really didn't see much of a disruption to making deadlines.

Without travel or meetings, interacting with our customers and the community was a challenge. PADT has hosted nine networking events for the Arizona technology business community since late spring and also hosted three panels for tech company executives and owners to discuss how to deal with COVID-19.

New and improved offerings and territories

We started the year by announcing our new community resource in March, 3dprinting-glossary.com. This free reference site offers definitions for over 250 terms used in Additive Manufacturing. It is slowly making its way up the list on Google search, and every month we see more and more users. As the industry grows, we will continue to keep it up to date.

Speaking of 3D Printing, our next big milestone was our expansion into Texas for Stratasys sales and support. We have been selling Ansys in the Lone Star state for several years and were pleased when, as a Stratasys Elite Channel Partner, we were asked to add Texas to our existing territory of Ansys, Colorado, New Mexico, and Utah.

We kept the ball rolling when Art Newcomer relocated to New Mexico to support our growing customer base in that state. Art is one of our field service engineers and is an expert in maintaining and getting the most out of Stratasys AM systems.

Then just last month, we officially announced a new EOS M 290 system at PADT, greatly increasing our ability to provide Metal 3D Printing Services. The new system will be used to manufacture components for customers and conduct R&D projects.

Simulation also saw some new offerings. As Ansys, Inc. continues to add new simulation tools to their portfolio, our team works to understand what they offer and introduces them to and supports them for our customers. In 2020 we saw noticeable growth in new users and consulting around LS-Dyna, Sherlock, and SPEOS. Ansys also added some new acquisitions in 2020 that we see great interest in: AGI for mission-level aerospace simulation and Lumerical for the modeling of photonics components.

New team members

This year also saw new employees joining the team. Over the year, we have added 5 engineers and 4 salespeople. That is good growth in any year but fantastic in the middle of a worldwide pandemic.

On top of these new team members spread across simulation, product development, and 3D Printing, we added two critical senior staff members to help us grow to the next level.

  • Dr. Keng Hsu, a recognized expert on Metal 3D Printing who joined us as Principal R&D Engineer, Additive Manufacturing.
  • Dr. Tyler Shaw also came on board in the second half of the year as our new Director of Engineering, leading our consulting team.
Dr Keng Hsu and Dr Tyler Shaw

New challenges in 2021

Which brings us to 2021. Like most people, we will be working under #covidrules through the first quarter and maybe even a bit into April or May. With this schedule in mind, here is what we plan to do while still dealing with the pandemic and after:

  • Pandemic-mode
    • Keep our employees safe
    • Add some new and exciting 3D Printing technologies.
    • Grow our recent expansion in California and Texas with additional staff and activities
    • Listen to our customers and deliver what they need to be successful.
    • Find new and interesting ways to get information into the hands of our customers. We are all a bit "zoomed-out."
    • Upgrade our compute infrastructure and continue to explore cloud solutions for business and engineering applications.
    • Host more events for the community
    • Remember to unmute at least 75% of the time.
  • Post-Pandemic-Mode
    • Look back on what worked and didn't work, and modify how we travel, meet, and communicate to take advantage of what we learned.
    • Get out and see as many of our customers as possible face-to-face.
    • Make further investments in people and resources in Texas and California, building on our growth in both states in 2020.
    • Go to lunch with our co-workers.
    • Have an Arizona Tech Business Networking event in person.
    • Throw our annual Nerdtoberfest Open House at PADT's headquarters in Tempe, Arizona
    • Have a 3D Printing Users Meeting in Colorado, outside, at a brewery.

Thank you!

This post has been purposefully upbeat. Although the business side of things has gone well, all things considered, it has been a stressful year, and many in the PADT extended family have struggled and dealt with serious health issues because of this virus.

As we close out 2020, a truly memorable year, we simply want to thank everyone who joined us on this journey for both helping us along the way and for letting us help you get through it.
