This video shows a really quick and easy way to extract a fluid domain from a structural model without having to do any Boolean subtract operations.
- It has been a long time since I have written any articles. I thought to get me back into the flow of writing I would share a recent fun project that I completed at work where I was able reuse and re-purpose abandoned 20 year-old office desks. The issue started out a frustration related to note taking and I wanted something better. What is my frustration, how did it start? It was started by simple pet peeve of my own. I do not like using paper to jot down quick ideas, thoughts or a to-do on! I write numerous quick notes down during my day at work.
Some examples of my daily office dilemma:
- Rapid fire phone calls that can bounce my phone off the desk.
- I just have to jot something down less than a single sentence down.
- A conference call occurs I need to capture a couple quick thoughts down because I am such a great active listener and don’t want to interrupt.
- Even sketching out a quick design for a new CUBE HPC cluster or workstation.
My whys may not be your whys and I feel like it is a time & resource waste! You might too especially when I the thoughts go something like this.
- Use a new piece of paper to write quick notes on? Nope
- Find the special square colored sticky things? Nope
- Dig through the paper recycling bin and get strange looks from my co-workers? Nope
- Cut my own square colored sticky note things? Nope
- I can’t seem to find a pen, open a brand new box of pens? Nope
- Take your notes on the electronic device of your choosing, okay which one phone, laptop, and/or tablet or how about use that conference room computer? Then I end up having quick notes and scribbles EVERYWHERE!
I hope those points made you laugh and frames a picture that I was not in my comfort zone. I knew what I wanted. I had used the same note taking process for years. Probably every day I would use my two whiteboards to write quick notes on. Whiteboards worked for me, I loved my whiteboards and life was good. What happened and where the frustration occurred was that I had four office desk moves over a time span of a year at PADT, Inc. Guess what happened the new office areas did not have whiteboards in them!
Here is a picture of a bunch of abandoned desks here at PADT, Inc. I walk past desks like these every day. Then during the office moving a thought occurred to me that maybe I could use paste or mat whiteboard type surface to them and make a whiteboard type desk?
I figured that someone had already thought of the idea already and remembered about a business trip that I took to California this past year. I remember walking through the insides of startup lab office building. You could feel the venture capital money pulsing through the office walls. This office building environment was sophisticated and exciting. What did I notice? I am sure you can think of some good examples. Haha, but what I found fascinating was groups of people collaborating with dry-erase markers in hand and notes scribbled over entire sections of walls. On huge conference room tables I even saw that large sections of glass walls where used. Boom! I had my solution.
I did my research and this is what I used.
The primer & the solution:
- Two primers can be used under Dry Erase Paint; either Zinsser B-I-N Shellac Based Primer or Zinsser Bulls-Eye 1-2-3 Water-based Primer.
- Rust-Oleum Dry Erase Kit
- About $50 and a few hours of time
- One package of the dry erase can do about 3-4 coats for a 30 sq ft area, or about two thick coast on two desks.
- Lightly sand the top until smooth.
- Clean the top of the desk.
- Mask the ends of the table
- Apply coat of primer
- Apply the solution
- After the third or fourth coat is on, wait 3 days for use.
We have been talking a lot about ANSYS AIM lately. Mostly because we really like ANSYS AIM and we think a large number of engineers out there need to know more about it and understand it’s advantages. And the way we do that is through blog posts, emails, seminars, and training sessions. A new tool that we have started using are “Resource and Productivity Kits,” collections of information that users can download.
Earlier in the year we introduced several kits, including ANSYS Structural, ANSYS Fluids, and ANSYS ElectroMechanical. Now we are pleased to offer up a collection of useful information on ANSYS AIM. This kit includes:
- “Getting to know ANSYS AIM,” a video by PADT application engineer Manoj Mahendran
- “What I like about ANSYS AIM,” a video featuring insights on the tool
- Six ANSYS AIM demonstration videos, including simulations and a custom template demonstration
- Five slide decks that provide an overview of ANSYS AIM and describe its new features
- An exclusive whitepaper on effectively training product development engineers in simulation.
You can download the kit here.
Watch this blog for more useful content on AIM in the future.
It seems like I’ve been explaining large deflection effects a lot recently. Between co-teaching an engineering class at nearby Arizona State University and also having a couple of customer issues regarding the concept, large deflection in structural analyses has been on my mind.
Before I explain any further, the thing you should note if you are an ANSYS Mechanical simulation user is this: If you don’t know if you need large deflection or not, you should turn it on. There is really no way to know for certain if it’s needed or not unless you perform a comparison study with and without it.
So, what are large deflection effects? In simple terms the inclusion of large deflection means that ANSYS accounts for changes in stiffness due to changes in shape of the parts you are simulating. The classic case to consider is the loaded fishing rod.
In its undeflected state, the fishing rod is very flexible at the tip. With a heavy fish on the end of the line, the rod deflects downward and it is then easy to observe that the stiffness of the rod has increased. In other words, when the rod is lightly loaded, a small amount of force will cause a certain downward deflection at the top. When the rod is heavily loaded however, a much larger amount of force will be needed to cause the tip to deflect downward by the same amount.
This change in the force amount required to achieve the same change in displacement implies that we do not have a linear relationship between force and displacement.
Consider Hooke’s law, also known as the spring equation:
F = Kx
Where F is the force applied, K is the stiffness of the structure, and x is the deflection. In a linear system, doubling the force results in double the displacement. In our fishing rod case, though, we have a nonlinear system. We might need to triple the force to double the displacement, depending on how much the rod is loaded relative to its size and other properties, and then to double the displacement again we might need to apply four times that force, just using numbers out of my head as examples.
So, in the case of the fishing rod, Hooke’s law in a linear form does not apply. In order to capture the nonlinear effect we need a way for the stiffness to change as the shape of the rod changes. In our finite element solution in ANSYS, it means that we want to recalculate the stiffness as the structure deflects.
This recalculation of the stiffness as the structure deflects is activated by turning on large deflection effects. Without large deflection turned on, we are constrained to using the linear equation, and no matter how much the structure deflects we are still using the original stiffness.
So, why not just have large deflection on by default and use it all the time? My understanding is that since large deflection adds computation expense to have it on, it’s off by default. It’s the same as for a lot of advanced usage, such as frictionless or frictional contact vs. the default bonded (simpler) behavior. In other words, turning on large deflection will trigger a nonlinear solution, meaning multiple passes through the solver using the Newton Raphson method instead of the single pass needed for a linear problem.
Here is an example of a simplified fishing rod. The image shows the undeflected rod (top), which is held fixed on the left side and has a downward force load applied on the right end. The bottom image shows the final deflected shape, with large deflection effects included. The deflection at the tip in this case is 34 inches.
In comparison running the same load with large deflection turned off resulted in a tip deflection of 40 inches. Thus, the calculated tip deflection is 15% less with large deflection turned on, since we are now accounting for change in stiffness with change in shape as the rod deflects.
Below we have a force (horizontal axis) vs. deflection (vertical axis) plot for a nonlinear simulation of a fishing rod with large deflection turned on. The fact that the curve is not a straight line confirms that this is a nonlinear problem, with the stiffness (slope of the curve) not constant. We can also see that as the force gets higher, the slope of the curve is more horizontal, meaning that more force is needed for each incremental amount of displacement. This matches our observations of the fishing rod behavior.
So, getting back to our original point, it’s often the case that we don’t know if we need to include large deflection effects or not. When in doubt, run cases with and without. If you don’t see a change in your key results, you can probably do without large deflection.
Here is an example using an idealized compressor vane. In this case, the deflections and stresses with and without large deflection effects are nearly the same (the stress difference is about 0.2%).
Bottom line: when in doubt, try it out, with and without large deflection. In ANSYS Mechanical, Large Deflection effects are turned on or off in the details of the Analysis Settings branch.
It’s worth noting that turning on large deflection in ANSYS actually activates four different behaviors, known as large deflection which include large rotation, large strain, stress stiffening, and spin softening. All of these involve change in stiffness due to deformation in one way or another.

What is this 3D Printing anyway? It doesn’t take long for someone new to the technology to see the wide range of applications and implications it brings to the table. But what how does it actually work. Our friends at Shapeways have put together a great infographic that explains things well.
Take a look and share:
If you scrolled down this far, you may be asking, “Why is PADT sharing Shapeways material? Are they not competitors?” Well, to be honest, we recommend Shapeways to people all the time. Our Additive Manufacturing business is about producing engineering prototypes, tooling, and end-use products for manufacturing companies. When a hobbiest or artist comes to ask us for a prototype, we often recommend that they go visit Shapeways.
We also recommend that people who are interested in all the non-engineering applications for 3D Printing check out their marketplace. The things that people have come up with is just amazing and shows the unbounded potential of this technology.
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
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:
- 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)
- Lowering power usage and increasing power density in batteries is a key driver
- The biggest issue in IoT is privacy and security. Keeping your data private and keeping people from hacking in to IoT devices.
- 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.
- 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:
PADT has a growing amount of experience with helping customers simulate and design IoT devices as well as the chips, sensors, and antenna that go in to IoT devices. To learn more, shoot us an email at email@example.com or call 480.813.4884.
Here 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 firstname.lastname@example.org or 480.813.4884. As always, visit www.PADTINC.com to learn more.
PADT is hosting a series of free training classes to introduce users to ANSYS AIM. We have pasted the invitation below. You can register here. We are very excited about this new tool from ANSYS, Inc. and are eager to share it with everyone. Look for more AIM information on this blog in the near future.
Terry 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!
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.
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!
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.
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.
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.
Among the magical skills engineers use in their daily awesomeness is their ability to bend the time fabric of the universe and perform tasks in almost impossible deadlines. It’s as if engineers work long hours and even work from home, while commuting and even at the coffee shop. Wait, is that what they actually do?
Among a myriad of tools that facilitate remote access and desktop redirection available, one stands out with distinction. NICE-Software developed a tool called Desktop Cloud Visualization (DCV for short). DCV has numerous advantages that we will get into shortly. The videos below give a general idea of what can be achieved with NICE-DCV.
Here is a video from the people at NICE:
And here is one of two PADT Employees using an iPhone to check their CFD results:
Advantages of Nice-DCV
Physical location of cluster/workstation or the engineers becomes irrelevant
Because engineers have fast, efficient and secure access to their workstations and clusters, they no longer need to be in the same office or on the same network segment to utilize the available compute resources. They can utilize NICE-DCV to create a fast, efficient and encrypted connection to their resources to submit, monitor and process results. The DCV clients are supported on Windows, Linux & IOS and even have a stand-alone Windows client that can be run on shared or public computers. In a recent live test, one of our engineers was travelling on a shuttle bus to a tiny ski town in Colorado, he was able to connect over the courtesy Wifi, check the status of his jobs and visualize some of the results.
The need for a powerful laptop or remote workstation to enable offsite work is no longer the only solution
There is no need for offsite engineers lug around a giant laptop in order to efficiently launch and modify their designs or perform simulation runs. Users launch the DCV client, connect to their workstation or cluster and are immediately given access to their desktop. No need to copy files, borrow licenses or transfer data. Engineers don’t need to create copies of files and carry them around on the laptops or on external storage which is an unnecessary security risk.
“If it ain’t broken don’t fix it!”
Every engineer uses ANSYS in his own special way. Some prefer the good old command line for everything even when a flashy GUI option is available. Others are comfortable using the Windows like GUI interface and would
Opens the door for GUI-only users to utilize large cluster resources without a steep learning curve or specialized tools.
Nice-DCV makes the use of ANSYS on large HPC clusters within reach for everyone. Engineers can log into pre-configured environments with all of the variables needed for parallel ANSYS runs already defined. Users can use can have their favorite ANSYS software added to the desktop as shortcuts or system admins can write small scripts or programs that serve as an answer file for custom job scripts.
From 0-60 in about…10 Minutes
For an engineer with the smallest amount of system administration skills it takes about 10 minutes to install the Nice-DCV server and launch the first connection. It’s surprisingly simple and straightforward on both the server and the client side. The benefits of Nice-DCV can be immediately realized in both simplified cluster administration and peace of mind for both the engineers and the system admins.
PADT’s CoresOnDemand and Nice-DCV
The CoresOnDemand service that PADT introduced last year utilizes the Nice-DCV tool to simplify and enhance the user experience.

In all the hype and hoopla around 3D Printing there are teams around the world that are quietly making a difference in manufacturing – making real parts and figuring out the processes, testing, and protocols needed to realize the dream of additive manufacturing. One such team is at Honeywell Aerospace, and we are proud to be one of their vendors.
They just published a great blog on where they are and what they have achieved and we recommend you give it a read. Very informative.

About Terry Wohlers
Terry Wohlers, founder of Wohlers Associates, Inc., a 28-year old independent consulting firm. 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, the 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.”
Anthony J. Lockwood, former editorial director, Desktop Engineering
Palm 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.
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.
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.
Below is a copy of the press release, or you can view the “official” version here.
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.
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.
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.
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.
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.
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.
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.

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.
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.
This 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.
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:
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.
