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.

Connection Groups and Your Sanity in ANSYS Mechanical

You kids don’t know how good you have it with automatic contact creation in Mechanical.  Back in my day, I’d have to use the contact wizard in MAPDL or show off my mastery of the ESURF command to define contacts between parts.  Sure, there were some macros somewhere on the interwebs that would go through and loop for surfaces within a particular offset, but for the sake of this stereotypical “old-tyme” rant, I didn’t use them (I actually didn’t, I was just TOO good at using ESURF to need anyone else’s help).

Image result for old tyme

Hey, it gets me from point A to B

In Mechanical contact is automatically generated based on a set of rules contained in the ‘Connection Group’ object:

image

It might look a little over-whelming, but really the only thing you’ll need to play around with is the ‘Tolerance Type’.  This can either ‘Slider’ or ‘Value’ (or use sheet thickness if you’re working with shells).  What this controls is the face offset value for which Mechanical will automatically build contact.  So in the picture shown above faces that are 5.9939E-3in apart will automatically have contact created.  You can play around with the slider value to change what the tolerance

image image image

As you can see, the smaller the tolerance slider the larger the ‘acceptable’ gap becomes.  If you change the Tolerance Type to be ‘Value’ then you can just directly type in a number.

Typically the default values do a pretty good job automatically defining contact.  However, what happens if you have a large assembly with a lot of thin parts?  Then what you run into is non-sensical contact between parts that don’t actually touch (full disclosure, I actually had to modify the contact settings to have the auto-generated contact do something like this…but I have seen this in other assemblies with very thin/slender parts stacked on top of each other):

image

In the image above, we see that contact has been defined between the bolt head and a plate when there is clearly a washer present.  So we can fix this by going in and specifying a value of 0, meaning that only surfaces that are touching will have contact defined.  But now let’s say that some parts of your assembly aren’t touching (maybe it’s bad CAD, maybe it’s a welded assembly, maybe you suppressed parts that weren’t important).

image

The brute force way to handle this would be to set the auto-detection value to be 0 and then go back and manually define the missing contacts using the options shown in the image above.  Or, what we could do is modify the auto-contact to be broken up into groups and apply appropriate rules as necessary.  The other benefit to this is if you’re working in large assemblies, you can retain your sanity by having contact generated region by region.   In the words of the original FE-guru, Honest Abe, it’s easier to manage things when they’re logically broken up into chunks.

image

Said No One Ever

Sorry…that was bad.  I figured in the new alt-fact world with falsely-attributed quotes to historical leaders, I might as well make something up for the oft-overlooked FE-crowd.

So, how do you go about implementing this?  Easy, first just delete the default connection group (right-mouse-click on it and select delete).  Next, just select a group of bodies and click the ‘Connection Group’ button:

image image image

In the image series above, I selected all the bolts and washers, clicked the connection group, and now I have created a connection group that will only automatically generate contact between the bolts and washers.  I don’t have to worry about contact being generated between the bolt and plate.  Rinse, lather, and repeat the process until you’ve created all the groups you want:

image

ALL the Connection Groups!

Now that you have all these connection groups, you can fine-tune the auto-detection rules to meet the ‘needs’ of those individual body groups.  Just zooming in on one of the groups:

image

By default, when I generate contact for this group I’ll get two contact pairs:

image image

While this may work, let’s say I don’t want a single contact pair for the two dome-like structures, but 2.  That way I can just change the behavior on the outer ‘ring’ to be frictionless and force the top to be bonded:

image

I modified the auto-detection tolerance to be a user-defined distance (note that when you type in a number and move your mouse over into the graphics window you will see a bulls-eye that indicates the search radius you just defined).  Next, I told the auto-detection not to group any auto-detected contacts together.  The result is I now get 3 contact pairs defined:

image image image

Now I can just modify the auto-generated contacts to have the middle-picture shown in the series above to be frictionless.  I could certainly just manually define the contact regions, but if you have an assembly of dozens/hundreds of parts it’s significantly easier to have Mechanical build up all the contact regions and then you just have to modify individual contact pairs to have the type/behavior/etc you want (bonded, frictionless, symmetric, asymmetric, custom pinball radius, etc).  This is also useful if you have bodies that need to be connected via face-to-edge or edge-to-edge contact (then you can set the appropriate priority as to which, if any of those types should be preserved over others).

So the plus side to doing all of this is that after any kind of geometry update you shouldn’t have much, if any, contact ‘repair’ to do.  All the bodies/rules have already been fine tuned to automatically build what you want/need.  You also know where to look to modify contacts (although using the ‘go to’ functionality makes that pretty easy as well).  That way you can define all these connection groups, leave everything as bonded and do a preliminary solve to ensure things look ‘okay’.  Then go back and start introducing some more reality into the simulation by allowing certain regions to move relative to each other.

The downside to doing your contacts this way is you risk missing an interface because you’re now defining the load path.  To deal with that you can just insert a dummy-modal environment into your project, solve, and check that you don’t have any 0-Hz modes.

Exploring High-Frequency Electromagnetic Theory with ANSYS HFSS

I recently had the opportunity to present an interesting experimental research paper at DesignCon 2017, titled Replacing High-Speed Bottlenecks with PCB Superhighways. The motivation behind the research was to develop a new high-speed signaling system using rectangular waveguides, but the most exciting aspect for me personally was salvaging a (perhaps contentious) 70 year old first-principles electromagnetic model. While it took some time to really understand how to apply the mathematics to design, their application led to an exciting convergence of theory, simulation, and measurement.

One of the most critical aspects of the design was exciting the waveguide with a monopole probe antenna. Many different techniques have been developed to match the antenna impedance to the waveguide impedance at the desired frequency, as well as increase the bandwidth. Yet, all of them rely on assumptions and empirical measurement studies. Optimizing a design to nanometer precision empirically would be difficult at best and even if the answer was found it wouldn’t inherently reveal the physics. To solve this problem, we needed a first-principles model, a simulation tool that could quickly iterate designs accurately, and some measurements to validate the simulation methodology.

A rigorous first-principles model was developed by Robert Collin in 1960, but this solution has since been forgotten and replaced by simplified rules. Unfortunately, these simplified rules are unable to deliver an optimal design or offer any useful insight to the critical parameters. In fairness, Collin’s equations are difficult to implement in design and validating them with measurement would be tedious and expensive. Because of this, empirical measurements have been considered a faster and cheaper alternative. However, we wanted the best of both worlds… we wanted the best design, for the lowest cost, and we wanted the results quickly.

For this study, we used ANSYS HFSS to simulate our designs. Before exploring new designs, we first wanted to validate our simulation methodology by correlating results with available measurements. We were able to demonstrate a strong agreement between Collin’s theory, ANSYS HFSS simulation, and VNA measurement.

Red simulated S-parameters strongly correlated with blue measurements.

To perform a series of parametric studies, we swept thousands of antenna design iterations across a wide frequency range of 50 GHz for structures ranging from 50-100 guide wavelengths long. High-performance computing gave us the ability to solve return loss and insertion loss S-parameters within just a few minutes for each design iteration by distributing across 48 cores.

Sample Parametric Design Sweep

Finally, we used the lessons we learned from Collin’s equations and the parametric study to develop a new signaling system with probe antenna performance never before demonstrated. You can read the full DesignCon paper here. The outcome also pertains to RF applications in addition to potentially addressing Signal Integrity concerns for future high-speed communication channels.

Rules-of-thumb are important to fast and practical design, but their application can many times be limited. Competitive innovation demands we explore beyond these limitations but the only way to match the speed and accuracy of design rules is to use simulations capable of offering fast design exploration with the same reliability as measurement. ANSYS HFSS gave us the ability to, not only optimize our design, but also teach us about the physics that explain our design and allow us to accurately predict the behavior of new innovative designs.

3D Printing Student Projects at PADT: Visit our Open House to Learn More (Thursday, March 2, 5pm)

Thursday, March 2 is PADT’s annual SciTech Festival Open House, from 5-8pm (click HERE to register). This year, three student groups working on a range of projects will be present to showcase their work, all of which involved some level of 3D printing. Please bring friends and families to meet and discuss ideas with these students from our community.

Formula SAE Team (Arizona State University)

ASU’s Formula SAE team will be onsite with their 2016 cardemonstrating specifically how they used 3D printing to manufacture the functional intake manifolds on these cars. What is specifically interesting is how they have modified their manifold design to improve performance while leveraging the advantages of 3D printing, and also they have evaluated multiple materials and processes over the recent years (FDM, SLS).

Prosthetic Arm Project (BASIS Chandler)

Rahul Jayaraman will be back to discuss how he and 30 students at BASIS Chandler manufactured, assembled and delivered about 20 prosthetic hands to an organization that distributes these to children in need across the world. Rahul and PADT were featured in the news for this event.

Cellular Structures in Nature (BASIS Chandler)

A BASIS Chandler High School senior, Amy Zhang, just started her Senior Research Project with PADT, focusing on a project at the intersection of biology and 3D printing, investigating cellular structures that occur on surfaces in nature, like the wing of a dragonfly or the shell on a turtle or the encasing of a pineapple – all of which are comprised of cellular geometries. Using 3D scanning, image analysis and mathematical methods, Amy hopes to develop models for describing these structures that can then be used in developing design principles for 3D printing. You can learn more on Amy’s blog: http://shellcells.blogspot.com/

Importing Material Properties from Solidworks into ANSYS Mechanical…Finally!

Finally! One of the most common questions we get from our customers who use Solidworks is “Why can’t I transfer my materials from Solidworks? I have to type in the values all over again every time.”  Unfortunately, until now, ANSYS has not been able to access the Solidworks material library to access that information.

There is great news with ANSYS 18.  ANSYS is now able to import the material properties from Solidworks and use them in an analysis within Workbench.  Let’s see how it works.

I have a Solidworks assembly that I downloaded from Grabcad.  The creator had pre-defined all the materials for this model as you can see below.

Once you bring in the geometry into Workbench, just ensure that the Material Properties item is checked under the Geometry cell’s properties.  If you don’t see the panel, just right-click on the geometry cell and click on Properties.

Once you are in ANSYS Mechanical, for example you will see that the parts are already pre-defined with the material specified in Solidworks .

The trick now is to find out where this material is getting stored. If we go to Engineering Data, the only thing we will see is Structural Steel. However when we go to Engineering Data Sources that is where we see a new material library called CADMaterials.  That will show you a list of all the materials and their properties that were imported from a CAD tool such as Solidworks, Creo, NX, etc.

You can of course copy the material and store it for future use in ANSYS like any other material.  This will save you from having to manually define all the materials for a part or assembly from scratch within ANSYS.

Please let us know if you have any questions and we’ll be happy to answer them for you.

Phoenix Business Journal: What’s the next tech from ‘Star Trek’ to become reality?

It should be no surprise to anyone that I love Star Trek.  So when we had a lunch discussion (as we often do) about Star Trek technology it was the perfect topic for a blog post.  In “What’s the next tech from ‘Star Trek’ to become reality?”  I present my case for two technologies that should be next: Tricorder and Shuttlecraft.  Some may argue that universal translator is even closer.

Learn About the New Stratasys 3D Printers and New Orleans

It was my first time visiting New Orleans. I have heard many stories of how good the food is and how everyone is really nice there so I was excited to visit this city for a business trip. Stratasys Launch 2017! There was some buzz going on about some new FDM printers that Stratasys has been working on and I was really excited to see them and hear what sets them apart from the competition. Rey Chu (Co-Owner of PADT), Mario Vargas (Manager of 3D Printer Sales), Norman Stucker (Account Executive in Colorado), and I (James Barker, Application Engineer) represented PADT at this year’s Launch.

The city did not disappoint! I ate the best gumbo I’ve ever tried. Below is a picture of it with some Alligator Bourbon Balls. The gumbo is Alligator Sausage and Seafood. Sooooo Good!!


My last night in New Orleans, Stratasys rented out Mardi Gras World. That is where they build all the floats for Mardi Gras. They had a few dancers and people dressed up festive. I was able to get a picture of Rey in a Mardi Gras costume.

After dinner at Mardi Gras World, I took Rey and Mario down Bourbon Street one last time and then we went to Café Du Monde for their world famous Beignets. Everyone told me that if I come home without trying the Beignets, then the trip was a waste. They were great! I recommend them as well. Below is picture of Mario and me at the restaurant.

As you can see we had a fun business trip. The best part of it was the unveiling of the new FDM printers! Mario and I sat on the closest table to the stage and shared the table with Scott Crump (President of Stratasys and inventor of FDM technology back in 1988). These new printers are replacing some of Stratasys entry level and mid-level printers. What impressed me most is that they all can print PLA, ABS, and ASA materials with the F370 being able to print PC-ABS. You also can build parts in four different layer heights (.005, .007, .010, and .013”), all while utilizing new software called GrabCad Print.

GrabCad Print is exciting because you can now monitor all of you Stratasys FDM printers from this software and setup queues. What made me and many others clap during the unveiling is that with GrabCad Print you no longer have to export STL files! You can import your native CAD assemblies and either print them as an assembly or explode the assembly and print the parts separately.

      

Everyone wants a 3D Printer that can print parts faster, more accurately and is dependable. You get that with the family of systems! Speed has increased big time, they are twice as fast as the Dimension line of FDM printers. Stratasys has published the accuracy of these new printers to be ±.008” up to a 4 inch tall part and then every inch past 4 inches, you add another .002”. These machines are very dependable. They are replacing the Uprint (Uprint SE Plus is still current), Dimension, and Fortus 250 machines that have been workhorses. Many of our customers still have a Dimension from 2002 when they were first launched. In addition to the 43 existing patents that Stratasys has rolled into this phenomenal product, they have an additional 15 new patents that speaks volumes as to the innovation in these 3D printers.

Stratasys Launch was a blast for me. Seeing these new printers, parts that were printed from them, and understanding why these are the best FDM printers on the market was well worth my time! I look forward to helping you with learning more about them. Please contact me at james.barker@padtinc.com for more information. If you would like to hear my recorded webinar that has even more information about the new F170, F270, and F370, here is the link.  Or you can download the brochure here.
