Additive Manufacturing: 3D Printing a Metal Shift Knob for Faster Cooling

When Nathan Huber moved to Arizona from Colorado to join PADT he learned a lot, and one of the things he learned fast was that the inside of cars get very hot in the summer here.  In fact, the shift knob on his car was untouchable in July.  This coincided with his learning more about metal 3D Printing and an idea occurred, what about 3D Printing a metal shift knob designed to cool off faster, and that looked cool.  Oh, and use ANSYS to drive the design.

He blogged about it before (here and here), and Additive Manufacturing online picked up the story and added to it on their blog post “3D Printing a Metal Shift Knob for Faster Cooling”  Check it out, they did a nice job of explaining what we did and how Nathan used several of our tools like ANSYS Mechanical and our Concept Laser metal system to realize the design.

 

3D Printing Peer Group of New Mexico Tech Council Launching on June 22

We are very pleased to announce the launch meeting of the newest New Mexico Technology Council peer group: 3D Printing.  After the success of other peer groups, and a similar committee in the Arizona Technology Council, PADT is partnering with the NMTC to start a group focused on all things Additive Manufacturing, which is the more technical name for 3D Printing. Schools, businesses, and individuals who have any involvement or interest in this exciting and transformative technology will be able to network and organize to get greater value from 3D Printing. This includes understanding the technology, working together on research projects, and getting to know what services are available locally.  It will also serve as a platform to coordinate the use of 3D printing in STEM education.

    

For this launch event, PADT’s Rey Chu will share his thoughts on the latest and most interesting advancements in 3D Printing.

What: NMTC 3D Printing Peer Group Launch

Advanced ANSYS Functionality

Just like any other marketplace, there are a lot of options in simulation software.  There are custom niche-codes for casting simulations to completely general purpose linear algebra solvers that allow you to write your own shape functions.  Just like with most things in life, you truly get what you pay for.

Image result for get what you pay for

 

For basic structural and thermal simulations pretty much any FE-package should suffice.  The difference there will be in how easy it is to pre/post process the work and the support you receive from the vendor.  How complicated is the geometry to mesh, how long does it take to solve, if you can utilize multiple cores how well does it scale, how easy is it to get reactions at interfaces/constraints…and so on.  I could make this an article about all the productivity enhancements available within ANSYS, but instead I’ll talk about some of the more advanced functionalities that differentiate ANSYS from other software out there.

  • Radiation

You can typically ignore radiation if there isn’t a big temperature gradient between surfaces (or ambient) and just model your system as conduction/convection cooled.  Once that delta is large enough to require radiation to be modeled there are several degrees of numerical difficulty that need to be handled by the solver.

First, radiating to ambient is fairly basic but the heat transfer is now a function of T^4.  The solver can also be sensitive to initial conditions since large DT results in a large heat transfer, which can then result in a large change in temperature from iteration to iteration.  It’s helpful to be able to run the model transiently or as a quasi-static to allow the solver to allow some flexibility.

Next, once you introduce surface to surface radiation you now have to calculate view factors prior to starting the thermal solution. If you have multiple enclosures (surfaces that can’t see each other, or enclosed regions) hopefully there are some processes to simplify the view factor calculations (not wasting time calculating a ‘0’ for elements that can’t radiate to each other).  The view factors can sometimes be sensitive to the mesh density, so being able to scale/modify those view factors can be extremely beneficial.

Lastly you run into the emissivity side of things.  Is the emissivity factor a function of temperature?  A function of wavelength?  Do you need to account for absorption in the radiation domain?

Luckily ANSYS does all of this.  ANSYS Mechanical allows you to easily define radiation to ambient or surface-to-surface.  If you’re using symmetry in your model the full radiating surface will be captured automatically.  You can define as many enclosures as possible, each with different emissivity factors (or emissivity vs Temperature).  There are more advanced features that can help with calculating view factors (simplify the radiating surface representation, use more ray traces, etc) and there is functionality to save the calculated view factors for later simulations.  ANSYS fluid products (CFX and Fluent) can also account for radiation and have the ability to capture frequency-based emissivity and participating media.

Different enclosures to simplify view factor calculations

Long story short…you don’t have to know what the Stefan-Boltzman constant is if you want to include radiation in your model (bonus points if you do).  You don’t have to mess with a lot of settings to get your model to run.  Just insert radiation, select the surface, and run.  Additional options and technical support is there if necessary.

  • Multiple/Multi-physics

I’d expect that any structural/thermal/fluids/magnetics code should be able to solve the basic fundamental equations for the environment it simulates.  However, what happens when you need to combine physics, like a MEMs device.  Or maybe you want to take some guess-work/assumptions out of how one physics loads another, like what the actual pressure load is from a CFD simulation on a structural model.  Or maybe you want to capture the acoustic behavior of an electric motor, accounting for structural prestress/loads such as Joule heating and magnetic forces.

image

ANSYS allows you to couple multiple physics together, either using a single model or through data mapping between different meshes.  Many of the data mapping routines allow for bi-directional data passing so the results can converge.  So you can run an magnetic simulation on the holding force between a magnet and a plate, then capture the deflected shape due to an external load, and pass that deformed shape back to the magnetic simulation to capture the updated force (and repeat until converged).

image

If you have vendor-supplied data, or are using another tool to calculate some other results you can read in point cloud data and apply it to your model with minimal effort.

image

To make another long story short…you can remove assumptions and uncertainty by using ANSYS functionality.

  • Advanced Material Models

 

Any simulation tool should be able to handle simple linear material models.  But there are many different flavors of ‘nonlinear’ simulation.  Does the stiffness change due to deflection/motion (like a fishing rod)?  Are you working with ductile metals that experience plastic deformation?  Does the stiffness change due to parts coming into/out-of contact?  Are surfaces connected through some adhesive property that debonds under high loads?  Are you working with elastomers that utilize some polynomial form hyper-elasic formulation?  Are you working with shape memory alloys?  Are you trying to simulate porous media through some geomechanical model?  Are you trying to simulate a stochastic material variation failure in an impact/explosive simulation?

image

Large deflection stiffness calculations, plasticity, and contact status changes are easy in ANSYS.  Debonding has been available since ANSYS 11 (reminder, we’re at release 18.0 now).  ANSYS recently integrated some more advanced geomechanical models for dam/reservoir/etc simulations.  The explicit solver allows you to introduce stochastic variation in material strengths for impact/explosive simulations.

image

ANSYS also has all the major flavors of hyper-elastic material models.  You can choose from basic Neo-Hookean, Arruda-Boyce, Gent, all the way through multiple variations of Mooney-Rivlin, Yeoh, Ogden, and more.  In addition to having these material models available (and the curve fitting routines to properly extract the constants from test data) ANSYS also has the ability to dynamically remesh a model.  Most of the time when you’re analyzing the behavior of a hyperelastic part there is a lot of deformation, and what starts out as a well-shaped mesh can quickly turn into a bad mesh.  Using adaptive meshing, you can have the solve automatically pause the solution, remesh the deformed shape, map the previous stress state onto the new nodes/elements, and continue with the solution.  I should note that this nonlinear adaptive remesh is NOT just limited to hyperelastic simulations…it is just extremely helpful in these instances.

The ending of this story is pretty much the same as others.  If you have a complicated material response that you’re trying to capture you can model it in ANSYS.  If you already know how to characterize your material, just find the material model and enter the constants.  We’ve worked with several customers in getting their material tested and properly characterized.  So while most structural codes can do basic linear-elastic, and maybe some plastic…very few can capture all the material responses that ANSYS can.

  • MEMs/Piezo/Etc

I know I’ve already discussed multiple physics and advanced materials, but once you start making parts smaller you start to get coupling between physics that may not work well for vector-based coupling (passing load vectors/deformations from one mesh to another).  Luckily ANSYS has a range of multi-physics elements that can solve use either weak or strong coupling to solve a host of piezo or MEM-related problems (static, transient, modal, harmonic).  Some codes allow for this kind of coupling but either require you to write your own governing equations or pay for a bunch of modules to access.

If you have the ANSYS Enterprise-level license you can download a free extension that exposes all of these properties in the Mechanical GUI.  No scripting, no compiling, just straight-up menu clicks.

image

Using this extension you can define the full complex piezoelectric matrix, couple it with an anisotropic elasticity matrix, and use frequency dependent losses to capture the actual response of your structure.  Or if you want you can use simplified material definitions to get the best approximation possible (especially if you’re lacking a full material definition from your supplier).

 

Long story short…there are a lot of simulation products out there.  Pretty much any of them should be able to handle the basics (single part, structural/thermal, etc).  What differentiates the tools is in how easy it helps you implement more real-world conditions/physics into your analysis.  Software can be expensive, and it’s important that you don’t paint yourself into a corner by using a single point-solution or low-end tool.

Thoughts from my day in a smart home – the importance of connecting right

When I was asked to take part in a demonstration put on by one of our local communication companies, Cox Communications, showing off what a “smart home” looks like, I of course said yes.  I love gadgets, and smart gadgets more.  On top of that it was another chance to evangelise on the power of 3D Printing.  And I got to hang out in a brand new luxury condo in Downtown Phoenix, a post kid lifestyle change that is very appealing.  Plus we deal with customers designing and improving Internet of Things (IoT) devices all the time, and this is the perfect chance to see such products in action.

So I packed up one of our Makerbots, none of our Fortus machines fits in the back of my Prius, and headed downtown.  The first thing that shocked me was that I had the printer, my iPhone, iPad, and laptop connected to their network in about one minute.  The printer showed up on the Makerbot Print app on my iPad and I was printing a part in about three minutes.

My station, showing off 3D Printing in the home.

The whole point of the demonstration was to show how the new high-speed Internet offering from Cox, Gigablast, can enable a true smart home.  So I was focused on the speed of the connection to the Internet, which was fast.  What I didn’t get till I connected was that the speed and bandwidth of the WiFi in the house was even more important.

When everything was connected, we had 55 devices on the local network talking to each other and the Internet. At one point I was downloading a large STL file to the printer while on a teleconference on my iPhone and my “roommate” was giving a violin lesson to one of his students in Canada.

Oh, and the roomba started to vacuum the floor. On the balcony someone was giving a golf lesson and a doctor was diagnosing a patient in the master bedroom.  That was on top of the smart kitchen gadgets.  And it all worked.  Yes, it all worked.

I’m trying to convey shock and surprise because the reality is that nine times out of ten when I show up for some event, at a customer, or at a friends house and we try and connect things to the internet… it doesn’t work.  If you are a technical guy you know that feeling when your vacation or visit for dinner turns into an IT house call.  All I could think of was how awesome it was that everything worked and it was fast.

So I went to work printing little plastic Arizona style houses with COX on the roof. And then a reporter showed up. “3D Printing, interesting.  Hmmmm…  they are cool and all but really, what does that have to do with a smart house?”  Damn reporters and their questions.  I was still reveling in the fact that everything worked so well, I hadn’t taken to time to think about the “so what.”

Then I thought about it.  3D Printing in the home is just now starting to take off, and the reason why is actually high-speed internet connections. If you wanted a 3D Printer in your home in the past you needed the printer, a high end computer, and some good 3D modeling software on that computer.  Basically you had to create whatever you wanted to make.  Unless you are a trained engineer, that may not be so easy.

My “house” that I was printing at the invent sits on the cloud in my Thingiverse account.

But with a well connected home you have access to places like Thingiverse and Grabcad to download stuff you want to print.  And if you do want to create your own, you can go to Tinkercad or Onshape and use a free online 3D modeler to create your geometry.  All over the web, even on a pad, phone (I don’t recommend trying to do modeling on a phone, but it does work), or on a basic computer.  The files are stored in the cloud and downloaded directly to your printer.  No muss, no fuss.  All you need is a reliable and fast connection to the internet and in your home.

High speed internet and a smart 3D printer makes anyone a maker.

And when we had a three hour break, I went downstairs to a coffee shop on the ground floor of the condo and worked, while monitoring my builds using the camera in the smart 3D Printer.

Pretty cool when you step back and think about how far we have come from that first Stereolithography machine that PADT bought in 1994.  We had to use floppy disks to get the data from our high-end Unix workstation to the machine.  Now it sits on the web and can be monitored.

This may be what we have been waiting for when it comes to 3D Printers in the home moving beyond that technologists and makers.

I’ve been focused on my experience with the 3D printing in the smart home, but there was a lot more to look at.  Check out these stories to learn more:

Phoenix Business Journal: Cox shows off a smart home with 55 connected devices and fast gigabyte internet

The Arizona Republic: Cox ‘smart home’ in Phoenix displays future at the push of a button

I also did a piece for the Phoenix Business Journal while I was at the event on “3 keys to success for smart home devices” based on what I learned while playing with the other devices in the smart home.

All and all a good day.  Oh, and being a 10 minute walk from my favorite pub made the idea of living downtown not such a bad idea, which doesn’t have much to do with high speed internet, connected devices, or 3D Printing.  But one of my goals was to check out post-child urban living…

Making Solids Water Tight in ANSYS Spaceclaim for ANSYS Workbench Meshing

Occasionally when solid geometry is imported from CAD into ANSYS SpaceClaim the geometry will come in as solids, but when a mesh is generated on the solids the mesh will appear to “leak” into the surrounding space. Below is an assembly that was imported from CAD into SpaceClaim. In the SpaceClaim Structure Window all of the parts can be seen to be solid components.

When the mesh is generated in ANSYS Mechanical it appears like the assembly has been successfully meshed.

However, when you look at the mesh a little closer, the mesh can be missing from some of the surfaces and not displayed correctly on others.

Additionally, if you create a cross-section through the mesh, the mesh on some of the parts will “leak” outside of the part boundaries and will look like the image below.

Based on the mesh color, the mesh of the part in the center of the assembly has grown outside of the surfaces of the part.
To repair the part you need to go back to SpaceClaim and rebuild it. First you need to hide the rest of the parts.

Next, create a sketch plane that passes through the problem part.

In the sketch mode create a rectangle that surrounds the part. When you return to 3D mode in SpaceClaim, that rectangle will become a surface that passes through the part.

Now use the Pull tool in SpaceClaim to turn that surface into a part that completely surrounds the part to be repaired, making sure to turn on the “No Merge” option for the pull before you begin.

After you have pulled the surface into a solid, it should like the image below where the original part is completely buried inside the new part.

Now you will use the Combine tool to divide the box with the original part. Select Combine from the Tool Bar, then select the box that you created in the previous step. The cutter will be activated and you will move the cursor around until the original part is highlighted inside the box. Select it with the left mouse button. The Combine tool will then give you the option to select the part of the box that you want to remove. Select the part that surrounds the original part. After it is finished, close the combine tool and the Structure Tree and 3D window will now look like the following:

Now move the new solid that was created with the Combine tool into the location of the original part and turn off the original one and re-activate the other parts of the assembly. The assembly and Structure Tree should now look like the pictures below.

Now save the project, re-open the meshing tool, and re-generate the mesh. The mesh should now be correct and not “leaking” beyond the part boundaries.

License Usage and Reporting with ANSYS License Manager Release 18.0

Remember the good old days of having to peruse through hundreds and thousands of lines of text in multiple files to see ANSYS license usage information?  Trying to hit Ctrl+F and search for license names.  Well those days were only about a couple months ago and they are over…well for the most part.

With the ANSYS License Manager Release 18.0, we have some pretty nifty built in license reporting tools that help to extract information from the log files so the administrator can see anything from current license usage to peak usage and even any license denials that occur.  Let’s take a look at how to do this:

First thing is to open up the License Management Center:

  • In Windows you can find this by going to Start>Programs>ANSYS Inc License Manager>ANSYS License Management Center
  • On Linux you can find this in the ansys directory /ansys_inc/shared_files/licensing/start_lmcenter

This will open up your License Manager in your default browser as shown below.   For the reporting just take a look at the Reporting Section.  We’ll cover each of these 4 options below.

License Management Center at Release 18.0

License Reporting Options

 

 

VIEW CURRENT LICENSE USAGE

As the title says, this is where you’ll go to see a breakdown of the current license usage.  What is great is that you can see all the licenses that you have on the server, how many licenses of each are being used and who is using them (through the color of the bars).  Please note that PADT has access to several ANSYS Licenses.  Your list will only include the licenses available for use on your server.

Scrolling page that shows Current License Usage and Color Coded Usernames

You can also click on Show Tabular Data to see a table view that you can then export to excel if you wanted to do your own manipulation of the data.

Tabular Data of Current License Usage – easy to export

 

 

 

VIEW LICENSE USAGE HISTORY

In this section you will be able to not only isolate the license usage to a specific time period, you can also filter by license type as well.  You can use the first drop down to define a time range, whether that is the previous 1 month, 1 year, all available or even your own custom time range

Isolate License Usage to Specific Time Period

Once you hit Generate you will be able to then isolate by license name as shown below.  I’ve outlined some examples below as well.  The axis on the left shows number of licenses used.

Filter Time History by License Name

1 month history of ANSYS Mechanical Enterprise

 1 month history of ANSYS CFD

Custom Date Range history of ANSYS SpaceClaim Direct Modeler

 

 

 

VIEW PEAK LICENSE USAGE

This section will allow you to see what the peak usage of a particular license during a particular time period and filter it based on data range.  First step is to isolate to a date range as before, for example 1 month.  Then you can select which month you want to look at data for.

Selecting specific month to look at Peak License Usage

Then you can isolate the data to whether or not you want to look at an operational period of 24/7, Monday to Friday 24/5 or even Monday to Friday 9am-5pm.  This way you can isolate license usage between every day of the week, working week or normal working hours in a week. Again, axis on left shows number of licenses.

Isolating data to 24/7, Weekdays or Weekday Working Hours

 Peak License Usage in March 2017 of ANSYS Mechanical Enterprise (24/7)

Peak License Usage in February 2017 of ANSYS CFD (Weekdays Only)

 

 

VIEW LICENSE DENIALS

If any of the users who are accessing the License Manager get license denials due to insufficient licenses or for any other reason, this will be displayed in this section.  Since PADT rarely, if ever, gets License Denials, this section is blank for us.  The procedure is identical to the above sections – it involves isolating the data to a time period and filtering the data to your interested quantities.

Isolate data with Time Period as other sections

 

 

Although these 4 options doesn’t include every conceivable filtering method, this should allow managers and administrators to filter through the license usage in many different ways without needing to manually go through all the log files.   This is a very convenient and easy set of options to extract the information.

Please let us know if you have any questions on this or anything else with ANSYS.

Kids, Race Cars, and Scanned Turtle Shells: PADT’s 2017 SciTech Festival Open House

There is something about a kid running down a hallway screaming “mom, you HAVE to see this!” #openhousegoals.

Last night was our annual event where we open up the doors of PADT with a family oriented event sharing what we engineers do.  We also invited some students from high school and University to share their engineering activities.  With over 250 attendees and more than one excited kid running down the hall, we can safely call it a success.

Attendies were able to see our 3D Printing demo room including dozens of real 3D printed parts, learn about engineering, explore how 3D Printing works, and check out our new metal 3D Printer. They were also able to learn about school projects like the ASU Formula SAE race car as well as a prosthetic hand project and research into cellular structures in nature from BASIS Chandler.

Oh, and there was Pizza.

Pictures speak louder than words, so here is a galary of images from the event.

Metal 3D Printed Shift Knob: Is It Cool(er)?

I had a really great time designing the Metal 3D printed shift knob from my previous blog post. I was curious what the other benefits of the knob may be besides being cool to look at and show off. What better way than to use the simulation software that we use here at PADT every day!

One of the clear differences between my solid spherical knob and the Metal 3D printed version is surface area. Being that PADT is based in Tempe, AZ, some may say that we have “warm” summers down here. Couple the 120F days with a black car, and the interior can get very hot, at some points feeling like the sun itself has taken up residence inside the back seat. With modern A/C, this heat can be mitigated fairly quickly, only to attempt to shift into gear to be scalded by the shift knob!

I wanted to see what the rate of cooling for the two knobs would be in a basic situation with some basic assumptions. Using ANSYS transient thermal, I initialized the knobs to 150F, temperatures that can be quickly reached in parked cars here in AZ. I added a convection heat transfer boundary condition on the outer surface of each shift knob, assuming a film coefficient of 50 W/m^2C, and that the ambient temp in the car is at a cool 70F.

 

I ran the simulations for 5 minutes, and the results were in line with what I expected. As the 3D printed knob has more surface area for cooling, it’s final temperature was ~84F, compared to the solid spherical knob at a final temperature of 115F!

Reveling in Speed and Technology – Tesla Test Drive Day at PADT

We have great customers.  The kind of cusomers that call up and ask “Hey, what do you think about having a Tesla test drive event for PADt employees”  Duh.  Yes.  Please provide contact information.

Then we thought this was an event better shared with other techno-speed-nerds. The Tempe Tesla show room people liked the idea so we put together an event for our ANSYS and Stratasys customers. (Just another reason to buy from us)

The basic idea was simple, stop on by the PADT parking lot in Tempe and drive a Tesla Model S or Model X, or both.  The Tesla people brought along their technical person and the test drive people were also very knowledgable about all the features in the three vehicles they let us drive. The course left the PADT parking lot, drove up to Elliot, then entred to 101, and then get off at Warner or Rey and head back, while the brave Tesla employee tried to keep cool. Especially when Oren was driving.

For many of us, this was the first time we had driven one.  Let me just say that the common factor across employees and cusotmers is that everyone had an ear-to-ear grin on their face when they got back from their test drive.  These cars are not just fast (large numbers of electrons pushed through big motors equals lots of torque right away) but they are brilliantly engineered. From the user interface, to the seats to, to the suspension. Everything is done right.  As a group of engineers that was almost as exciting as the raw power and impecable styling of the cars.

It was a true nerdfest.  We spent 10 minutes discussing regenerative breaking schemes and the idea of using regeneration all the time when you lift off the accerator instead of putting your foot on the break to slow down slightly.  This is the type of paradigm shift that disrupts around one hundred years of automotive legacy.  Why does the accelrator pedal have to be an accelerator pedal. Why can’t it be an input for acceleration and deceleration based on position?  We also spent even more time (I’m embarassed to say how long) talking about charging.  And then the topic turned to autonomous driving and the sensors used.  Good times.  Good times.

PADT’s relationships with Tesla actually goes way back. When they were first starting out and were just a handfull of engineers, we provided some ANSYS training and did a consulting job for them on thermal management for an early battery system.  So we proudly count them as a happy PADT customer.  And of course PADT worked on the large Blink chargers and has supported many companies that are suppliers to tesla.

Look for similar events in the future. No sales or seminars, just smart-people-fun type of events. 

 

Update on ASU 3D Printing Research and Teaching Lab

Two weeks ago we were part of a fantastic open house at the ASU Polytechnic campus for the grand opening of the Additive Manufacturing Research center, a part of the Manufacturing Research and Innovation Hub.  What a great event it was where the Additive Manufacturing community in Arizona gathered in one place to celebrate  this important piece in the local ecosystem.  A piece that puts Arizona in the lead for the practical application of 3D Printing in industry.

I could go on and on, but better writers by far have penned some great stories on the event and on the lab.

ASU’s article is here: New hub’s $2 million in cutting-edge 3-D printing equipment will allow students to stay on forefront of rapidly growing sector

And Hayley Ringle of the Phoenix Business Journal summed it all up, with some great insight into the impact on education and job growth in “See inside the Southwest’s largest 3D printing research facility at ASU

And last but not least, here are some pictures related to PADT that ASU provided:

PADT Named ANSYS North American Channel Partner of the Year and Becomes an ANSYS Certified Elite Channel Partner

The ANSYS Sales Team at PADT was honored last week when we were recognized four times at the recent kickoff meeting for the ANSYS North American Sales orginization.  The most humbling of those trips up to the stage was when PADT was recognized as the North American Channel Partner of the Year for 2016.  It was humbling because there are so many great partners that we have had the privilege of worked with for almost 20 years now.  Our team worked hard, and our customers were fantastic, so we were able to make strides in adding capability at existing accounts, finding new customers that could benefit from ANSYS simulation tools, and expanding our reach further in Southern California.  It helps that simulation driven product development actually works, and ANSYS tools allow it to work well.

Here we are on stage, accepting the award:

PADT Accepts the Channel Partner of the Year Award. (L-R: ANSYS CEO Ajei Gopal, ANSYS VP Worldwide Sales and Customer Excellence Rick Mahoney, ANSYS Director of WW Channel Ravi Kumar, PADT Co-Owner Ward Rand, PADT Co-Owner Eric Miller, PADT Software Sales Manager Bob Calvin, ANSYS VP Sales for the Americas Ubaldo Rodriguez

We were also recognized two other times; for exceeding our sales goals and for making the cut to the annual President’s Club retreat.   As a reminder, PADT sells the full multiphysics product line from PADT in Southern California, Arizona, New Mexico, Colorado, Utah, and Nevada.  This is a huge geographic area with a very diverse set of industries and customers.

In addition, ANSYS, Inc. announced that PADT was one of several Channel Partners who had obtained Elite Certified Channel Partner status. This will allow PADT to provide our customers with better services and gives our team access to more resources within ANSYS, Inc.

Once we made it back from the forests and hills of Western Pennsylvania we were able to get a picture with the full sale team.  Great job guys:

We could not have had such a great 2016 without the support of everyone at PADT. The sales team, the application engineers, the support engineers, business operations, and everyone else that pitches in.   We look forward to making more customers happy in 2017 and coming back with additional hardware.
