Webinar: PADT Answers your Questions on Metal 3D Printing

Direct Laser Melting systems have made fantastic improvements in the last five years or so, making 3D Printing of metal parts a reality.  The accuracy and strength of the finished parts rivals cast parts in the same material, but with the advantages of Freeform Fabrication.  In fact, everywhere we go, people have questions about Metal 3D Printing.

So we decided to hold a webinar to answer those questions all at once.  Our manufacturing team, lead by Dhruv Bhate, PhD, will share with you what we have learned while working to develop our own metal 3D Printing capability and while consulting with many of our customers as they acquired their own systems.

ANSYS, Inc. Launches New Magazine, Dimensions

ansys_dimensions-1There are so many aspects to numerical simulation worth talking about these days, and a lot of resources to get that information.  Applications, theory, how-to, and where it fits into the business of making stuff. Here on The Focus we tend to concentrate on practical hot-to things, and the ANSYS Advantage magazine has focused on the application stories along with some how-to. What has been missing a a resource for how simulation impacts business, and how users of simulation are making other improvements in their business.

ansys_dimensions-3Enter “Dimensions.”  This new e-publication is from the same team that does the ANSYS Blog and  ANSYS Advantage, but it has a decided business slant – WAIT!!!.  I know, your an engineer, the world “business” scares you.  Don’t worry, this is value added info, not a bunch of fluff.

Take a look at the first issue here.  I’ll be honest, I kind of ansys_dimensions-5opened up expecting to page through going “whatever,” “right, no one does that,” and “who cares.”  But I found myself skimming all of the articles with interest, and reading a couple completely.  There is some good stuff in here.  LIke an interview with Airbus engineers on about the challenge they face in designing their products. Or who Whirlpool uses social networking to facilitate communication between their users around the world. There is some simulation stuff in there, like how Siemens Power leverages simulation to make better power generation products.  And a lot more.

Take a look, it won’t hurt, I promise.  If you want something more technical, forward the link to your boss at least.

Denver Business Journal: Colorado Companies Bringing Space Costs Down to Earth

dbj-Denver-Business-Journal-logoColorado is a major contributor to the space industry, and they are quickly adopting 3D Printing to keep costs down and get to space faster.  In this article, “Colorado Companies Bringing Space Costs Down to Earth” the DBJ explores how automation and 3D Printing can have a big impact on cost and schedule.  Many of the companies sighted in the article are PADT customers, and PADT’s very own Norman Stucker was quoted extensively for the article.

LinkedIn: Why is 3D Printing Such a Big Deal

LinkedIn_logo_initialsThe recent explosion of interest in 3D printing has been fascinating to engineers like myself that have been using what we call Additive Manufacturing as a standard tool for over two decades. It is easy to dismiss the interest of the general public and the media as hype and trendiness. But doing so would be a mistake. It is a big deal, but not for the reasons that most people think.  “Why is 3D Printing Such a Big Deal” explains what the real power is behind 3D Printing.

Christmas Left-Right Gift Exchange Story: Star Wars Adventure

For our Christmas parties at PADT we generally have over 40 employees so a traditional secret Santa gift exchange takes to long. So a couple of years ago we downloaded a right-left gift exchange story from the internet and it was a big hit. We ran out of stories on the internet, so we started writing our own, usually in some sort of over-the-top style.  This year, 2015, we had started the day of the party by attending the new Star Wars movie, so the story had to be Star Wars related.

Everyone gets their gift and forms a big circle in the middle of the room.  Someone with a strong voice reads the story and every time the world LEFT is read, everyone passes the package they have to the left. Every time the world RIGHT is read, everyone passes the package they have to their right.  You should pause a bit at each LEFT/RIGHT to give people a chance to pass.

A long time ago in a galaxy far far, away…

San To Claas is in trouble. Right next to the Right-torna system on the left side of the Galaxy, the planet Northpoliax, in a left hand orbit around the star Leftonia 37, was the galactic hub for all thing Christmas. Gifts left the system right after the planet’s winter solstice. But nothing left on this orbit. Because right above the largest continent on Northpoliax, a Death Star hovered. Threatening Christmas for everyone, no one was left out.

A new Sith lord, Darth Rightis, hated Christmas. All that cheer and spirit left him cold inside. Two much of the light side of the force. Just the thought of all those gifts left for younglings left him angry. But help was right around the corner. A squadron of Xwing fighters was following right behind the Millennium Falcon.

“Arffhhhhdghgg ” said Chewy.

“What? The moon on the left or the one on the right?” Asked Han Solo. Chewy gestured and Hans went to the left.

“Your other left” yelled Princess Leia. Han dived right behind the moon on the left and slingshoted right toward the Death Star, the Xwings right behind them.

The lead pilot said: “Red leader this is blue leader. You take the left side. We will take the left as well, right after you attack, those bastards won’t expect that.”
“Right” Responded blue leader.

Han added: “We will soften up that left side for you. Then let loose the “big present” after both your attacks on the left. The warhead should go right in and end this madness. “

As they approached the Millennium Falcon put covering fire to the right, then veered to the right, leaving the left open. The Xwings attacked, diving right into the slot and trying not to hit either side, the left or the right. The first attack on the left left the defenses damaged. The second attack on the left was right on target. That left the run of the Millennium Falcon. It released a plasma bomb that was wrapped in a big red package, with a bow right on top. As Han pulled up and to the left, and then the right, the warhead exploded right on inside of the main power coupler. Chewy, sitting in the right seat, bellowed in victory as the Death Star exploded right under them. As the debris clears a hologram image appeared right in the middle of the cabin.

It showed Admiral San To Clause, wearing his red uniform with white fur epilets on the right and left shoulders.

“Thank you all for coming right when we needed you. Right now, Christmas is saved and the dark side is left with one less Sith Lord. May the force, be right with you. And Merrrrrry Christmas to all!

Arizona Chief Science Officers Design Their Own 3D Printed Name Badges

az-scitech-cso-badges-3d-printed-0The Chief Science Officer program is a program for 6th-12th grade students to represent their school in STEM. And what better way is there for them to identify themselves then with 3D Printed name badges?  The program’s sponsors, the AZ SciTech Festival offer a training retreat for the kids who get elected as their school’s CSO and we all thought introducing design and 3D Printing would be a great activity.

As part of the 2015 Fall CSO Institute, PADT’s Jeff Nichols joined local designer and artist John Drury to spend some time with the kids explaining how to work with logos and shapes to convey an idea, and how to design for 3D Printing.  The kids worked out their own design and sent it to PADT for printing.

We converted their sketch into a 3D Model, starting in Adobe Illustrator. The sketch was traced with vector geometry and then a generic name was added. This was then copied 144 times and each name was typed in, with a few extras. This step was the only boring part.

az-scitech-cso-badges-3d-printed-6

The design worked great because it is a simple extrusion with no need for support material.    The outline of their names were exported as DXF from Illustrator and then imported onto the 3D Model and extruded up to make a solid model of a badge. This was then copied to make a badge for each student. Then the names were imported and extruded on the patterned badges.

az-scitech-cso-badges-3d-printed-5
The was a simple extrusion for each feature, allowing for contrast and readability but keeping things simple.
az-scitech-cso-badges-3d-printed-4
This project was a great opportunity to use both patterns and importing 2D drawings. By laying everything out in a grid, we only had to make one badge and copy that. Then import the names and extrude those on the patterned badges.

STL files were then made and sent off to one of our Stratasys FDM 3D Printers. The FDM (Fused Deposition Modeling) process extrudes an ABS plastic filament, and you can change material during the build. So, to add a bit of contrast, we changed the filament color after the base of the design was done, making the logo and student names stand out.  The final results came out really nice.

az-scitech-cso-badges-3d-printed-1
This is what they look like right out of the machine. We swapped out two color for each build. With some clever packing, we were able to get 12 badges on each platform.
az-scitech-cso-badges-3d-printed-2
The final products really stand out.

This project was a lot of fun because we were able to work with the students. They got what John and Jeff taught them and did a great job.  We know they will be placed with pride on back backs and jackets across Arizona.

Star Wars – The Force Awakens with PADT

padt-star-wars-vii-5For an engineer, there are certain TV and Movie experiences that border on the religious – Star Wars is of course one of those.  That is why PADT’s main office in Tempe closed down today to head down the freeway to the Chandler to see Star Wars VII: The Force Awakens.

Around 370 employees, family members, friends, vendors, former employees, and customers showed up for the 10:00 am showing.  We were confident that JJ Abrams would do a great job, because he did so well with an even more important franchise to PADT, Star Trek.  We were not disappointed.  There were cheers, there was laughter, and several of us confessed in the lobby afterwards that we teared up a bit.  A true treat.

padt-star-wars-vii-1
We had a 410 seat theater and about 350 RSVP’s . So we got a bit nervous as the seats filled up. We did get more unexpected people then we cancellations, but we had plenty of room and the more the merrier. Bottom line, the first two rows were empty. So prefect.

I want to thank Josh Heaps here for putting it all together and for dealing with our constantly asking him about when and where it was and how many seats the theater had.

padt-star-wars-vii-2
My friend Ryan, one of AZ’s biggest Star War fans, and our fantastic V.P from Chase, Camille, were great sports who dressed up and posed for pictures. Not only does Camille constantly help make our banking a great experience, she jumps right in with our engineering fun.

This is also a great venue to thank our customers and vendors for coming and for bringing your families.  We don’t get to see many of you often enough, and rarely outside of a meeting or a phone call.  Seeing the smiles on everyone’s face after the movie was, as they say, worth the price of admission.

May the Force Be With You

Activating Hyperdrive in ANSYS Simulations

punch-it-chewie-ansysWith PADT and the rest of the world getting ready to pile into dark rooms to watch a saga that we’ve been waiting for 10 years to see, I figured I’d take this opportunity to address a common, yet simple, question that we get:

“How do I turn on HPC to use multiple cores when running an analysis?”

For those that don’t know, ANSYS spends a significant amount of resources into making the various solvers it has utilize multiple CPU processors more efficiently than before.  By default, depending on the solver, you are able to use between 1-2 cores without needing HPC licenses.

With the utilization of HPC licenses, users can unlock hyperdrive in ANSYS.  If you are equipped with HPC licenses it’s just a matter of where to look for each of the ANSYS products to activate it.

ANSYS Mechanical

Whether or not you are performing a structural, thermal or explicit simulation the process to activate multiple cores is identical.

  1. Go to Tools > Solve Process Settings
  2. The Solve Process Settings Window will pop up
  3. Click on Advanced to open up the Advanced Settings window
  4. You will see an option for Max number of utilized cores
  5. Simply change the value to your desired core count
  6. You will see below an option to allow for GPU acceleration (if your computer is equipped with the appropriate hardware)
  7. Select the GPU type from the dropdown and choose how many GPUs you want to utilize
  8. Click Ok and close
hyperdrive-ansys-f01
Go the proper settings dialog
hyperdrive-ansys-f02
Choose Advanced…
hyperdrive-ansys-f03
Specify the number of cores to use

Distributed Solve in ANSYS Mechanical

One other thing you’ll notice in the Advanced Settings Window is the option to turn “Distributed” On or Off using the checkbox.

In many cases Distributing a solution can be significantly faster than the opposite (Shared Memory Parallel).  It requires that MPI be configured properly (PADT can help guide you through those steps).  Please see this article by Eric Miller that references GPU usage and Distributed solve in ANSYS Mechanical

hyperdrive-ansys-f04
Turn on Distributed Solve if MPI is Configured

ANSYS Fluent

Whether launching Fluent through Workbench or standalone you will first see the Fluent Launcher window.  It has several options regarding the project.

  1. Under the Processing Options you will see 2 options: Serial and Parallel
  2. Simply select Parallel and you will see 2 new dropdowns
  3. The first dropdown lets you select the number of processes (equal to the number of cores) to use in not only during Fluent’s calculations but also during pre-processing as well
Default Settings in Fluent Launch Window
Default Settings in Fluent Launch Window
Options When Parallel is Picked
Options When Parallel is Picked

ANSYS CFX

For CFX simulations through Workbench, the option to activate HPC exists in the Solution Manager

  1. Open the CFX Solver Manager
  2. You will see a dropdown for Run Mode
  3. Rather than the default “Serial” option choose from one of the available “Parallel” options.
  4. For example, if running on the same machine select Platform MPI Local Parallel
  5. Once selected in the section below you will see the name of the computer and a column called Partitions
  6. Simply type the desired number of cores under the Partitions column and then either click “Save Settings” or “Start Run”
Change the Run Mode
Change the Run Mode
Specify number of cores for each machine
Specify number of cores for each machine

ANSYS Electronics Desktop/HFSS/Maxwell

Regardless of which electromagnetic solver you are using: HFSS or Maxwell you can access the ability to change the number of cores by going to the HPC and Analysis Options.

  1. Go to Tools > Options > HPC and Analysis Options.
  2. In the window that pops up you will see a summary of the HPC configuration
  3. Click on Edit and you will see a column for Tasks and a column for Cores.
  4. Tasks relate to job distribution utilizing Optimetrics and DSO licenses
  5. To simply increase the number of cores you want to run the simulation on, change the cores column to your desired value
  6. Click OK on all windows
hyperdrive-ansys-f09
Select the proper settings dialog
hyperdrive-ansys-f10
Select Edit to change the configuration
Specify Tasks and Cores
Specify Tasks and Cores

There you have it.  That’s how easy it is to turn on Hyperdrive in the flagship ANSYS products to advance your simulations and get to your endpoint faster than before.

If you have any questions or would like to discuss the possibility of upgrading your ship with Hyperdrive (HPC capabilities) please feel free to call us at 1-800-293-PADT or email us at support@padtinc.com.
