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.

GCOI 2015 – Celebrating Arizona’s Technology Community

gcoi_iconFor those of us that are part of the Arizona Technology community, the official kickoff of holiday and end of year celebrations is the Governor’s Celebration of Innovation, or GCOI.  A who’s who of key people from startups to large aerospace firms gather at the convention center to recognize students, academicians, companies, and individuals who have had a significant impact on the State’s high tech industries.  This is always a special evening for PADT because many of the attendees, and usually a few of the award winners, are our customers.

In fact, for 2015 we are proud to congratulate the following long time PADT customers who were recognized last night:

  • Medtronic Tempe Campus for Innovator of the Year, Large Company
  • Raytheon Missile Systems for winning the Pioneering Award
  • ASU’s Michael Crow, the OneNeck IT Services People’s Choice Lifetime Achievement Award winner (ASU is a large PADT customer… so we feel Dr. Crow is our customer as well.)

You can find a full list of winners and some great pictures  from the event in Tishin Donkersley’s article at AZ Tech Beat.

This fantastic event is put on by the Arizona Technology Council and the Arizona Commerce Authority.  For those that were there: Mac & Cheese bar FTW.

About the Awards

As in past years, PADT was honored to be able to fabricate the awards that were handed out. This year we used the overall design for the event, created by Atom, as our starting point. We used our Stratasys FDM printers to make the stair steps and “tech guy silhouette” The graphics are then printed on large stickers that are adhered to the back of an Arizona’ish shaped piece of plexiglass.

gcoi-awards-2015-1

The PADT Booth

This year we decided to not bring a 3D Printer and instead focus on parts made on a wider variety of printers. The hit for visitors were the metal parts that were made on ConceptLaser Direct Laser Melting systems.  In addition we got to talk about the great work that our product development team did for GlobalStar on the Spot devices and Orthosensor for their intelligent orthopedic sensors. We even had a few simulation people come by to talk ANSYS.

Presentation: Leveraging Simulation for Product Development of IoT Devices

SEMI-AZ-IOT-4

SEMI-AZ-IOT-5
Yours truly going over the impact of Simulation on IoT Product Development

The local SEMI chapter here in Arizona held a breakfast meeting on Monetizing Internet of Things (IoT) and PADT was pleased to be one of the presenters. Always a smart group, this was a chance to sit with people making the sensors, chips, and software that enable the IoT and dig deep in to where things are and where they need to be.

The event was hosted by one of our favorite customers, and neighbor right across the street, Freescale Semiconductor.  Speakers included IoT experts from Freescale, Intel, Medtronics, ASU, and SEMICO Research.

Not surprisingly I talked about how Simulation can play a successful role in product development of IoT devices.

You can download a copy of the presentation here: PADT-SEMI-IOT-Simulation-1.pdf

UPDATE (11/9/2015): Great write-up by Don Dingee on this event in the SemiWiki. Click here to read it. It includes a great summary of the other speakers.

You can also see more details on how people use Simulation for this application on the ANSYS, Inc. website here.  We also like this video from ANSYS that shows some great applications and how ANSYS is used with them:

A couple of common themes resonated across the speakers:

  1. Price and size need to come down on the chips used in IoT (this was a semiconductor group, so this is a big part of their focus)
  2. Lowering power usage and increasing power density in batteries is a key driver
  3. The biggest issue in IoT is privacy and security. Keeping your data private and keeping people from hacking in to IoT devices.
  4. Another big problem is dealing with all the data collected by IoT devices. How to make it useful and how to store it all.  One answer is reducing the data on the device, another is only keeping track of what changes.
  5. It is early, standards are needed but they are still forming.

If you look at this list, the first two problems are addressable with simulation:

Manufacturing Open House Highlights – October 2015

padt-mfg-openhouse-2015-1Here at PADT we help people who make products, stuff that gets manufactured.  So we focused our open house yesterday on advanced manufacturing and invited the community to come out and network, learn, and share.  Even though it was a busy week for technology events in Arizona, we had a great turnout on a surprisingly cloudy Wednesday evening.

October is Manufacturing month and this open house was part of the Arizona Commerce Authority’s coordinated events to highlight manufacturing in Arizona.   You can learn more about other events in the state here.

This event was a bit more casual and less structured then past PADT open houses, letting attendees spend more time one-on-one with various experts and dig deep in to technologies like metal 3D Printing, urethane casting, topological optimization, and scanning.

What struck all of us here was the keen interest in and knowledge about the various tools we were showing across a wide range of attendees.  From students with home built 3D Printers to managers from local aerospace companies that are on the forefront of Additive Manufacturing, the questions that were asks and comments that were made with insightful and show a transition of this technology from hype to real world application.

Below are some more quick snapshot taken during the event.

A big thanks to everyone who made it out and we hope to see more of you next time. If you have any questions about the application of advanced manufacturing technologies to your products, don’t hesitate to reach out to us at info@padtinc.com or 480.813.4884.  As always, visit www.PADTINC.com to learn more.

Beyond the Hype – Additive Manufacturing and 3D Printing Worldwide, A Summary of Terry Wholers’ Thoughts

3d-printing-terry-wholers-padt-1Terry Wholers is the founder and principal consultant of Wohlers Associates Inc., an independent consulting firm that was launched 28 years ago. Wohlers and his team have provided consulting work to over 240 organizations in 24 countries as well as to 150 companies in the investment community. He has authored over 400 books, articles, and technical papers. Terry has twice served as a presenter at the White House. For the past 20 years hes has been the principal author for the Wohlers Report which is an annual worldwide publication focused on Additive Manufacturing and 3D Printing. In 2007 more than a 1,000 industry professionals from around the world selected Terry as the most influential person in Rapid Prototyping Development and Additive Manufacturing.

PADT was fortunate enough to sponsor, with the local SME group, an event in Fort Collins, Colorado where Terry came and shared his views on the industry. What follows is a summary of what we learned. They are basically notes and observations.  Please contact us for any clarification or details: 

Terry Wohlers started his talk by asking: How many people have heard of 3D printing?

He noted that these days it was pretty much everyone and if you haven’t then you must be living in a cave. It is like everyone can’t get enough of it.

There has been a lot of growth. In the last 5 years the industry has quadrupled. Last year it was a 4.1 billion industry and this year 5.5 billion. Terry doesn’t own any stock in any of the different 3D printing companies. He cautioned everyone to not confuse the share prices with the growth and the expansion within this industry.

After this introduction, Terry stated that there were really two things in the industry that really excited him.  3D Printing for Manufacturing and for Production Parts.

3D Printing in Manufacturing.

The first area to watch is the use of this technology for manufacturing applications. The team looking at the sales data drew a line in the sand for the low cost hobbyist printers at $5,000. There were 140,000 of them sold last year compared to under 13,000 above $5k. However, they don’t cost much so the money is still in the industrial machines. Here are the revenues for 2014:

Industrial: 1.12 Billion, or 86.6%.
Hobbyist: 173.3 Million, or 13.4%

There are FDM clones everywhere. 300 or more brands. There is a lot of open source software out there to develop your own FDM printer.

One thing to watch in the industry is expiring patents. This opens up competition and lowers prices and sometimes brings better machines to market.  Right now, the SLS patent expired in June of last year so we are seeing new Selective Laser Sintering devices coming to market.

An exciting example of using 3D printing in manufacturing is the landing gear created by Stratasys. It was built and assembled with a Stratasys FDM printer and used for a fit check. Very Cool!

3d-printing-terry-wholers-padt-2

www.makepartsfast.com/2008/06/523/how-to-make-accurate-cad-to-stl-file-transitions

In medical, some great examples of tooling are jigs, fixtures, drill press, and custom cutting guide for knee replacement. You can take scanned data and create a custom cutting guide for replacing your knee. Tens of thousands of those have been done.

Lots of work is being done on test fixtures as well.

In tooling, with additive manufacturing you can do things that are highly complex. Instead of just straight gun drilled cooling channels you can make the cooling channels conform to the purpose of the part. You can reduce 30-300% cycle time by improving the cooling channels for injection molding dies.  It turns out that Lego is printing their molds! They are using conformal cooling to increase their cycle times.

On the aerospace side of things, end use parts are literally taking off.  Airbus is flying today 45,000 to 60,000 Ultem plastic parts. Both passenger and non-passenger planes have Ultem parts on them.

3D Printing for Final Production Parts

The second area to watch is the next frontier, and that is what excites him. You can do structural ribs in 3D printed parts. You need to make sure there are places in your parts to remove the support material used if you are going to use structural ribs. Design is absolutely critical. When he was at Solidworks world in Orlando a few years ago, there was a 3D printed bird that was flapping its wings.

This is a part of that bird that was being flown.

3d-printing-terry-wholers-padt-4 3d-printing-terry-wholers-padt-3
Two weeks ago Terry did a four day course at NASA on Design for Additive Manufacturing. The importance of the subject now is that companies and organizations are paying a lot of money to host people to teach them how to design for additive manufacturing. It was a great learning experience and NASA has already signed up for a second course that is focused on metals. NASA 3D printed a turbopump with 45%fewer parts that runs at 90,000 rpm, and creates 2,000 hp. This turbopump manufactured with conventional methods costs $220,000 for one, they can 3D print 2 of them in Inconel for $20,000.

A big part of Design for Additive Manufacturing is using the correct thinking but also using the right tools. There is a lack of both. We are taught to design for the conventional method of manufacturing. Now we have to undo some of that and think, hey there can be a better way to design this part.

One of those ways is Topology Optimization (let mathematics decide where to place the support structure so there is a increased strength to weight ratio). Another is the use of lattice structure (mesh and cellular). Ever since the beginning of time, man would make parts out of a solid material. Well now you can have a thin skin and a lattice structure on the interior to produce something superior in some cases.

We need these kind of tools integrated into the different CAD software’s so that we can design better parts.  This bracket is flying on a Airbus. This cabinet bracket is made out of titanium and is flying on the A35 Airbus. It was designed for 2.3 tons and actually holds up to 12.5-14 tons depending on the test. Peter Zander at Airbus believes that in 2 years they will be printing 30 tons of metal per month!

3d-printing-terry-wholers-padt-5

GE Aviation is building fuel nozzles for the new leap engine. The new design is 25% lighter and five times more durable than the previous design that took 20 different parts to assemble to make one fuel nozzle. The will be printing 40,000 fuel nozzles per year.

Consumer Products:
It is going to be very big. Terry thinks this is going to be a sweet spot in the industry. Once example is this guitar called the Hive Bass. It is built out of Nylon and would cost you $3,500. You can have a custom guitar made for that price.

3d-printing-terry-wholers-padt-6
There is a Belgium company that creates custom frames for eyewear.

3d-printing-terry-wholers-padt-7

There is also a lot of Jewelry available for consumers along with many other products.

For metal part production there are many steps needed to finish the part. About 9 steps that Terry counted so it can be a long process.

Myth: Additive Manufacturing is fast! Well that depends on Polymers versus Metals and the size and complexity of the parts. Airbus had one build that took 14 days to print with their metal printer! GE mentioned that they have to print the same part twice before they get it right because they will have to reorient the part or change the build parameters to get the best quality build possible.

According to some estimates the global manufacturing economy is in the range of $13 trillion. If this technology were to penetrate 2% of it then that is over a quarter of a trillion dollars. 5% is approaching two thirds of a trillion!

Terry finished by asking: How many of you think this will be North of the 5% estimate?

We want to thank Terry for giving such an informative talk, and New Belgium Brewing for hosting. The networking afterwords was fantastic. 

If you would like to stay up to date on 3D Printing, we recommend the Wohlers Report. It is our primary reference document here at PADT.

Wohlers and his team have provided consulting assistance to more than 240 organizations in 24 countries, as well as to 150+ companies in the investment community. He has authored 400 books, articles, and technical papers and has given 125 keynote presentations on five continents. Wohlers has twice served as a featured speaker at events held at the White House. He is a principal author of the Wohlers Report, wholers-logothe undisputed industry-leading study on additive manufacturing and 3D printing for 20 consecutive years.

Here is what industry experts have to say about Mr. Wohlers and his company’s industry report:

“Why waste time and money when you can get a worldwide overview of additive manufacturing from Wohlers Associates-experts that have focused on AM for 26 years. The Wohlers Report is worth every dollar.”

Peter Sander, Vice President, Airbus Germany

“Now in its 18th year of publication (that’s right all you 3-D printing arrivistes, this stuff has been around for a while), the annual report describes a healthy and growing market for 3-D printing equipment, services, materials and processes, albeit one where the value continues to accrue to industrial applications.”

Michael Copeland, Senior Editor, WIRED

“The amount of information in the report is almost overwhelming. I am awed by its depth and breadth. What’s more, the information is not available anywhere else. For example, we hear how China is changing, but few people fully understand the transformation that’s underway. The report gives insight and clarification on China and it covers the rest of the world with the same careful analysis. It also provides insight into new products and applications that you normally would not hear about, such as light-weight structures, nanomanufacturing, growing organs, gaming, and new types of protective gear. One of the secrets of your success is the extensive travel worldwide, coupled with the information you seek from experts globally. Thank you for making something so remarkable available each year.”

Boris Fritz, Northrop Grumman

“If you need to know anything about where this technology is today or where it is going tomorrow, Wohlers Report is your guide.”

Press Release: Southern California Expansion Grows PADT’s ANSYS Product Development Software Distribution Business

PADT-CA-License-PlatePalm trees and movie stars.  Endless beaches and deserts that fade to the horizon.  Aerospace companies, world class universities, med device developers, and toy manufacturers.  Oil, freeways, and big construction. Southern California. A place larger and more diverse than most countries in the world.  PADT has done work in the area since our first weeks in business. As our business continued to grow, our customers started asking when we were opening up a local office, but the time never seemed right. Until now.

PADT is pleased to announce that we will be loading furniture and computers in a truck and head on the I-10 to Torrance, California where we will open up a new office.  ANSYS, Inc. has expanded our sales territory to include small and medium sized new accounts in the Southern California area.  The focus of this new office will be building that business.

You can read the official details in the press release below, or the PDF here.  As usual, we want to share some more informal information with our blog readers.

The office will be started with an engineer and a salesperson who have been with us for a while, and another pair that we are hiring locally. This combination of company experience and local knowledge should get us going quickly. Over time, the plan is to grow the Torrance office, and add at least two more. Long term we would like to have between 3 and 10 employees per office in Southern California.

PADT-Torrance-Front-Building-1-W-PS-Logo-600w

Our team will conduct training and seminars from this office and use it as a base to spread the word on simulation driven product development across Southern California. The initial focus for sales will be on small and medium sized businesses that are currently not using ANSYS products, that want to work with a technical sales and support team who can provide more than the software tool – customers who want a partner who can also help them apply the tools effectively. The dense hotbeds of engineering along the coast will be an obvious area of concentration. We also aim to represent the value of ANSYS products in less visited areas of the region, including the high deserts, “in-between” towns, and inland locations beyond LA, Orange County, and San Diego.

PADT-CA-LA-PostCard

The good news is that we are not starting from scratch. This first office is right down the street from the California campus of PADT’s largest and oldest customer.  We also have over one hundred customers who have used PADT for simulation services, training, rapid prototyping, and product development, and we will be reaching out to them shortly to start building our local network even further.  And then, our new employees who we will hire locally will be contacting their network as well.

Before the end of the summer we hope to have a grand opening event, as well as several seminars that will continue through the end of the year. If you live in the area and want to be invited, visit here to register as someone who want to be on the California contact list.

This blog and social media will be used to post our progress. The entire sales and technical team is looking forward to meeting everyone in the area in the coming months.

If you have any questions or suggestions for us, please contact us.  Our standard number 480.813.4884 works for all of our offices.

Press Release:

Southern California Expansion Grows PADT’s ANSYS Product Development Software Distribution Business

PADT opens Torrance office to provide consultant-focused ANSYS Product Sales and Support for small and medium sized engineering businesses in the region

Tempe, Ariz., August 24, 2015 —Phoenix Analysis & Design Technologies, Inc. (PADT) the Southwest’s largest provider of Numerical Simulation, Product Development, and 3D Printing services and products, today announced the addition of Southern California to its ANSYS, Inc. Product Sales and Support territory. PADT is a long time ANSYS Channel Partner who has built a reputation for outstanding technical abilities and customer support in Arizona, New Mexico, Colorado, Utah, and Nevada. The company is now taking the same customer focused approach to selling and supporting the world’s leading product development simulation tools from ANSYS to new customers in Southern California.

“We are honored by ANSYS’ trust in PADT and are eager to start working more closely with their team in Southern California,” said Bob Calvin, PADT’s manager of Simulation Sales. “We have been doing business in this area since PADT was founded 21 years ago. Expanding our offering to include ANSYS products and support is something that makes sense for users, ANSYS and PADT.”

Located in Torrance California, PADT’s new office will be staffed by two sales people and two application engineers.  Aggressive growth will follow.

“We selected Torrance for our new Southern California office because it’s centrally located, easily accessible and right down the street from the California campus of our largest customer,” said Ward Rand, co-owner, PADT. “Having staff with real world industry experience located nearby will strengthen our ability to drive our customer’s product development process, resulting in higher quality products, improved performance and lower costs.”

PADT will open additional offices across the Southern California region in the coming two years with the long term goal of three total offices with three to ten employees each.  The location of these offices, just like the initial Torrance facility, will be chosen to provide service where the demand is greatest.

The ANSYS Channel Partner program is unique in the industry because it allows customers the option to purchase software and support from ANSYS directly, or from highly technical local consulting companies like PADT. Since Southern California has not had an ANSYS Channel Partner for thirteen years, PADT’s engineering experience and ANSYS product expertise will be a tremendous help to small and medium sized companies seeking to discover the power of ANSYS products, and efficiently implement Simulation Driven Product Development (SDPD).

Events, both on-line and face-to-face, will be announced in the coming months to celebrate the arrival of PADT in the area. Those interested in following PADT’s progress, can subscribe to any of the company’s social media outlets, PADT California emails, or visit the new PADT California web page (www.padtinc.com/socal).

CoresOnDemand: Helping Engineers Do Their Magic

CoresOnDemand-Logo-120hEngineers Do Magic

In the world of simulation there are two facts of life. First, the deadline of “yesterday would be good” is not too uncommon. Funding deadlines, product roll-out dates, as well as unexpected project requirements are all reliable sources for last minute changes. Engineers are required to do quality work and deliver reliable results in limited time and resources. In essence perform sorcery.

Second, the size and complexity of models can vary wildly. Anything from fasteners and gaskets to complete systems or structures can be in the pipeline. Engineers can be looking at any combination of hundreds of variables that impact the resources required for a successful simulation.

Required CPU cores, RAM per core, interconnect speeds, available disk space, operating system and ANSYS version all vary depending on the model files, simulation type, size, run-time and target date for the results.

Engineers usually do magic. But sometimes limited time or resources that are out of reach can delay on-time delivery of project tasks.

At PADT, We Can Help

PADT Inc. has been nostrils deep in engineering services and simulation products for over 20 years. We know engineering, we know how to simulate engineering and we know ANSYS very well. To address the challenges our customers are facing, in 2015 PADT introduced CoresOnDemand to the engineering community.

af-02

CoresOnDemand offers the combination of our proven CUBE cluster, ANSYS simulation tools and the PADT experience and support as an on demand simulation resource. By focusing on the specific needs of ANSYS users, CoresOnDemand was built to deliver performance and flexibility for the full range of applications. Specifics about the clusters and their configurations can be found at CoresOnDemand.com.

CoresOnDemand is a high performance computing environment purpose built to help customers address numerical simulation needs that require compute power that isn’t available or that is needed on a temporary basis.

Call Us We’re Nice

CoresOnDemand is a new service in the world of on-demand computing. Prospective customers just need to give us a call or send us an inquiry here to get all of their questions answered. The engineers behind CoresOnDemand have a deep understanding of the ANSYS tools and distributed computing and are able to asses and properly size a compute environment that matches the needed resources.

Call us we’re nice!

Two Halves of the Nutshell

The process for executing a lease on a CoresOnDemand cluster is quite straight forward. There are two parts to a lease:

PART 1: How many cores & how long is the lease for?

By working with the PADT engineers – and possibly benchmarking their models – customers can set a realistic estimate on how many cores are required and how long their models need to run on the CoresOnDemand clusters. Normally, leases are in one-week blocks with incentives for longer or regular lease requirements.

Clusters are leased in one-week blocks, but we’re flexible.

Part 2: How will ANSYS be licensed?

An ANSYS license is required in order to run on the CoresOnDemand environment.  A license lease can be generated by contacting any ANSYS channel partner. PADT can generate license leases in Arizona, Colorado, New Mexico, Utah & Nevada. Licenses can also be borrowed from the customer’s existing license pool.

An ANSYS license may be leased from an ANSYS channel partner or borrowed from customer’s existing license pool.

Using the Cluster

Once the CoresOnDemand team has completed the cluster setup and user creation (takes a couple of hours for most cases), customers can login and begin using the cluster. The CoresOnDemand clusters allow customers to use the connection method they are comfortable with. All connections to CoresOnDemand are encrypted and are protected by a firewall and an isolated network environment.

Step 1: Transfer files to the cluster:

Files can be transferred to the cluster using Secure Copy Protocol which creates an encrypted tunnel for copying files. A graphical tool is also available for Windows users (& it’s freeJ). Also, larger files can be loaded to the cluster manually by sending a DVD, Blu-ray disk or external storage device to PADT. The CoresOnDemand team will mount the volume and can assist in the copying of data.

Step 2: Connect to the cluster and start jobs

Customers can connect to the cluster through an SSH connection. This is the most basic interface where users can launch interactive or batch processing jobs on the cluster. SSH is secure, fast and very stable. The downside of SSH is that is has limited graphical capabilities.

Another option is to use the Nice Software Desktop Cloud Visualization (DCV) interface. DCV provides enhanced interactive 2D/3D access over a standard network. It enables users to access the cluster from anywhere on virtually any device with a screen and an internet connection. The main advantage of DCV is the ability to start interactive ANSYS jobs and monitor them without the need for a continuous connection. For example, a user can connect from his laptop to launch the job and later use his iPad to monitor the progress.

af-04

Figure 1. 12 Million cell model simulated on CoresOnDemand

The CoresOnDemand environment also has the Torque resource manager implemented where customers can submit multiple jobs to a job queue and run them in sequence without any manual intervention.

Customers can use SCP or ship external storage to get data on the cluster. SSH or DCV can be used to access the cluster. Batch, interactive or Torque scheduler can be used to submit and monitor jobs.

All Done?

Once the simulation runs are completed customers usually choose one of two methods to transfer data back. First is to download the results over the internet using SCP (mentioned earlier) or have external media shipped back (External media can be encrypted if needed).

After the customer receives the data and confirms that all useful data was recovered from the cluster, CoresOnDemand engineers re-image the cluster to remove all user data, user accounts and logs. This marks the end of the lease engagement and customers can rest assured that CoresOnDemand is available to help…and it’s pretty fast too.

At the end of the lease customers can download their data or have it shipped on external media. The cluster is later re-imaged and all user data, accounts & logs are also deleted in preparation for the next customer.

ANSYS Launches Free Student Version

ansys-student-1This week ANSYS, Inc. made a fantastic announcement that has been in the works for a while, and that we think will greatly benefit the simulation community:  A free ANSYS Student product.  This is an introductory product that is focused on students who are learning the fundamentals of simulation who also want to learn the full power and capability of the ANSYS product suite.  It includes ANSYS® Multiphysics™ , ANSYS® CFD™ , ANSYS® Autodyn®, ANSYS® Workbench™, ANSYS® DesignModeler™and ANSYS®DesignXplorer™

Yes you read that right, all of the flagship products for free. No features or capabilities are turned off. It is the exact same software as the commercial product, but the size of problems that you can solve is limited.  It runs on MS Windows. Perfect for students.

PADT is excited about this because it gives students access to the ability to learn FEA and CFD simulation with the world’s most popular and capable simulation tool, without running in to brick walls. Want to do a flat plate with a hole in it? No Problem. Want to model fluid-solid-interaction on a flexible membrane valve? No Problem.  Want to model explosive forming? No Problem.  Want to model combustion with complex turbulence? No problem.

All in the same interface as students will use when they enter the work force or do research at University.

This is great news and we can’t wait to see what schools and students do with this access.

How to Get It – The New Academic Web Pages

The previous Student Portal is being replaced with an Academic Web area on the ansys.com site: ansys.com/academic.

Go to the ANSYS Student site to learn more about ANSYS Student and how to download your copy. These same pages will have resources to help you learn and understand the product.

The “Pictures”

Let me state categorically that PADT was not consulted on the image that ANSYS, Inc. used for the “student” user that was so happy to find out that there is now a free version of the ANSYS software suite.  Here is their picture:

ANSYS-student-version We would have preferred something like this:

huge.1.7907

 

Just kidding. We were happy to see this product come out and thought the picture was hilarious.  In all seriousness, we will also plug the  recent #ilooklikeanengineer twitter hash tag , highlighting the diversity of female engineers. that was awesome and we would love to see more chances for engineers to show their true selves.

 

3D Printing the 4th Dimension – GISHWHES 2015 Scavenger Hunt

padt-sundial-insun-apple-watch-wGISHWHES is a huge international scavenger hunt. Every year teams around the globe comb through the list of 215 tasks and pick as many as possible that their team can do.  Last year they introduced 3D Printing as a task, and we helped a team 3D Print a quill pen. That was a lot of fun, so when this year’s list included an item on 3D printing, we jumped at the chance to be involved.

The item was:

110: VIDEO. Use a cutting edge 3D printer to 3D print your representation of the 4th dimension.62 POINTS

Being engineers we said “4th Dimension?  Time.”  Then it became a choice between the way mass distorts the space-time continuum or some sort of clock’ish thing.  The distortion thing seemed difficult so we focused on a clock.  Being that we were constrained on budget and time we decided to do a sundial.

The result can be seen here in this YouTube video.

It was a fun project and the team spent a bit of time in the 112F sunshine trying it out.  We can’t wait to see what we will get to do for the 2016 scavenger hunt.

Making the Model

A couple of people have asked if we downloaded the solid model for the sundial or if we made it. We actually made it. After a little bit of research we found that making a simple horizontal sundial like this one is very easy. Here are the steps we took:

Get Geometry Values

So it turns out that the angle of each hour line is determined by the latitude of where the dial will go. The angle of the pointy thing, called a gnomon, is also the latitude.  So for Tempe, AZ that is 33.4294°.That gets applied to the equation:

angle(h) = arctan(sin(L*tan(15° · h))

h = integer of the hour, 6 am to 6 pm
L = latitude

I plopped that into Excel:

=ABS(DEGREES(ATAN(SIN(RADIANS($C$3))*TAN(RADIANS(15)*B7))))

and got the following:

Latitude 33.4294
Hour Angle
6 90.00
7 64.06
8 43.66
9 28.85
10 17.64
11 8.40
12 0.00

Build the Solid Model

The next step is to build the model. I used SolidEdge because I know it real well and was able to knock it out quickly.  But all CAD tools would be the same:

  1. Pick a center point.
  2. Add lines as rays from that using the angles in the table above for each hour.
  3. Design the shape of your sundial to look cool. I did a simple circle .
  4. Mark the hours using the sketch. I raised up thin rectangles.
  5. Model the gnomon using the latitude as the angle.  Make this as fancy or simple as you want.
  6. Add whatever doo-dads you want.
  7. Label the hours if you want.
  8. Save to STL

Here is what my sketch looked like:PADT-sundial-cad-model-hour-sketc

And the final solid model looked like this:

PADT-sundial-cad-modelWe sent this to the printer as shown in the video, and got a sundial.

 

 

 

 

 

 

Major Enhancements in FLOWNEX 2015: Combustors, Importers, and Pipes

FlownexLogo_OfficialSimulation has revolutionized flow and heat transfer dependent systems over the past decades by minimizing costly physical testing and accelerating time to operation around the world. But for many companies, such simulation has largely focused on components and proved to be very time consuming. The technology advancements delivered by Flownex SE now offer a fast, reliable, and accurate total system and subsystem approach to simulation.

FLOWNEX-2015-ICONS

With the release of FLOWNEX 2015, users now have access to advanced combustor system level modeling and they can interact with more system and component simulation tools. This is on top of the already considerable capabilities found in the  tool

Gas Turbine Combustor Heat Transfer Library

During the Preliminary design phase or when considering modifications to existing combustor designs it’s essential to make realistic predictions of  mass flow splits through the  various air admission holes, total pressure losses liner temperatures along the length of the combustor etc.

FLOWNEX-2015-combustor-simulationAlthough very powerful, 3D CFD solutions of combustors are specialized, time consuming processes and therefore are seldom exclusively used during initial sizing of a combustor.

It has been demonstrated that 1D/2D network tools, like Flownex, are capable of predicting with reasonable accuracy the same trends as more detailed numerical models.

The advantage, however, is Flownex’s rapid execution, which allows design modifications and parametric studies to be conducted more simply than ever before. The ease of use and incredible speed of Flownex allows 1000s of preliminary designs to be evaluated under all modes of operation for steady state and dynamic cases. Furthermore, the data obtained from the one-dimensional analysis can be used as boundary conditions for a more detailed three-dimensional model, ultimately supplementing a typical combustor design work flow.

While the simulation of combustor systems was previously possible in the Flownex environment, much of the work of implementing industry standard heat transfer correlations was left to the user through scripting .Now in Flownex SE 2015 it’s all been built in to the tool, while maintaining the flexibility required to model any combustor configuration.

New components include

  • Film convection component
  • Fluid radiation component
  • Jet impingement heat transfer component

To sum up Flownex allows more accurate initial designs, less time is spent on advanced 3D combustor simulations and rig tests, thus reducing development time and cost.

Here is a Video that shows off these features:

Added importers and integration features

AFT Fathom/Impulse/Arrow importer

An importer was added to import the file formats of AFT products. The importer imports all the diameters, loss factors heights, etc. so 90% of the effort is done, and in some cases the networks solve without any modifications.

ROHR2 Integration (pipe stress analysis software)

Flownex has the ability to calculate forces during dynamic simulations. This is very useful in pipe stress analysis for surge or water hammer cases. The ability to import complete geometries from ROHR2 and export results in the format that ROHR2 expects natively has been added. This means a user can perform these combined analysis now with ROHR2 with the minimum of effort.

Fluid Importers

An Importer was added to import liquid and gas properties from CoolProp an open source fluid property library. The existing Aspen/Hysys fluid importer was changed to be a generic Cape-Open compliant importer. This means that fluid properties can now be imported from any Cape-Open compliant server software.

Product Development for Startups – Presentation at The Startup Lifecycle Lunch & Learn

PADT-Startup-Prod-DevThis Thursday PADT was asked to help participate in a lunch and learn entitled “The Startup Lifecycle.” The event was a joint presentation of the Arizona Technology Council and the Maricopa Corporate College and it was held at CEI’s fantastic facilities.  Given our background, we were asked to talk about Product Development, and specifically on Minimum Viable Products and Lean Manufacturing Principles.

You can download my presentation here, or read on to learn more about the event.

lunchandlearn2There were four presenters.  Hart Schafer the Founder & CEO of TheraSpace and an experienced Adobe guy, among other things, kicked things off with a great discussion on customer validation and discovery.  He pointed out the common mistakes in thinking you know your customers and finding out you were wrong to late. Some great examples were given and he shared some practical ways to really find the Problem-Solution fit.

Next was yours truly, talking about those uncomfortable bits in the middle, where you need to actually design your product, then make it.  I covered the concept of a Minimum Viable Product and how to use product development to come up with one. We also touched on how lean product development can be applied in a startup environment.

Then I dived into lean manufacturing, which is a topic worthy of several Lunch and Learns on its own.  The bottom line was that Startups can effectively apply lean manufacturing to get a better product to market faster, and on budget.  I included some examples and advice on how to implement it.

As mentioned above, you can download my presentation here.

This is a picture of me gesturing widely as I explained how a simple cake doughnut is a Minimum Viable Product and one with frosting and sprinkles was not.  All the time hearing Homer Simpson saying “doooonuts” in my head. presenting2

 

NExt up was Nate Curran, the Entrepreneur-in-Residence at CEI.  He went in to how to commercialize a product.  Another huge topic, but he boiled it down to some basics on commercialization, marketing, and sales.  The last speaker was Russ Yelton, the CEO of Pinnacle Transplant Technologies, a successful startup that was a client at CEI. After we talked about what you should do, he shared the real world and how to scale and grow. The big takeaway from his talk for me was the importance of people and culture when you scale and grow.

After a great Q&A session, we posed for a picture:

lunchandlearn-presenters

As always with events at CEI, the venue was great. And, also as always with AZ Tech Council events, the audience was smart, engaged, and full of their own ideas worth sharing.  Yet another indication of the growing and improving startup ecosystem in Arizona.

AmCon Phoenix 2015: Comments and Presentation Notes

prezo_padt_amcon_phoenix-2015We just finished up our third and final AmCon show of the year at what turned out to be the best show of the three.  The PADT booth was packed during the exhibition time with a wide variety of people asking questions and checking out examples of what PADT and Stratasys can do.  We were able to meet with a lot of our local customers, and even better, were able to get to know a ton of new potential clients.  Some shows are kind of boring and people just don’t get what we do. AmCon shows are the exact opposite. The attendees are smart, informed, and eager to learn more.

As is usual, we had a collection of parts on display. We also had a Geomagic Capture scanner showing off our growing offering of optical scanning solutions.  Here is a picture of Mario at the show.  He definitely photographs the best:

mario_padt_amcon_phoenix-2015In addition to the booth, we were asked to speak on 3D Printing at the event.  Yours truly gave a presentation entitled: “The Practical Application of 3D Printing for Prototyping, Tooling, and Production” that lasted a bit over an hour.

As promised the notes from that presentation can be downloaded here.

We hope to see more of you at future events. If you have questions about 3D Printing and its application please don’t hesitate to contact us.
