PADT Shows Golf “Participation” at Annual Phoenix Society of Manufacturing Engineers Tournament

Golf1

PADT has a great reputation for a lot of things: ANSYS expertise, the people solve those tough engineering problems in product development, outstanding knowledge and quality in rapid prototyping, the knowledge and enthusiasm of our employees. Notice that golf is not listed in there. It is still not listed.

This last Saturday was the annual Phoenix Chapter 067 Society of Manufacturing Engineers Golf Tournament. This well attended event is held to raise money towards scholarships for Manufacturing Engineering students at Arizona State University.  A great cause and the turnout was awesome with eighteen foursomes hitting the fairways at the Arizona Grand Resort. The picture above shows John, Brad, and Eric posing at the hole that PADT sponsored.  Our fourth player prefers to remain anonymous.

NiceCourse

John-GolfPADT hired the bulk of our manufacturing team from the ASU program and we support their efforts to educate future leaders in manufacturing technology. In fact, the picture to the right is of John taking a swing – he is a graduate of this program. Some of the things we do  include internships, onsite tours of our rapid manufacturing facility, lecturing, and donating items to and sponsoring their fundraising auctions.  We also sponsor breakfast and a hole at this event each year.  What we do not do is strike fear and trepidation in the hearts of the other golfers.

PADT-Last-Place-Golf

Sigh… 18th out of 18.  Note how they used a different color of ink to make sure everyone noticed we were last. We did get a consolation prize of a large box of golf balls, a not so subtle hint to get out there and practice more.

However, it was a very nice day and we had a great time out there.

 

Annual Halloween Pumpkin Fest Time at PADT

PADT-2013-Halloween-feastWe kicked off the first official event of the holiday season today with our Halloween Pumpkin Fest.  BBQ and “Pumpkin Inspired Dessert” were on the menu as we celebrate the return of awesome weather to Arizona when we can all leave our air-conditioned cubicles and venture outside and sit in the sun without melting.  Very nice.

For those that follow us, we are sad to report that there was no pumpkin launch this year. We have been swamped with work recently and our team of pumpkin projecting professionals just did not have the time to prepare the equipment this year.

We wish all of you a Happy Halloween and we look forward to Thanksgivukkah, Christmas, and the New Year and enjoying a strong end to a great 2013!

 

 

What is Going on with MakerBot’s Acquisition by Stratasys?

Back in June it was announced that Stratasys was acquiring MakerBot. Many of you have been asking about the acquisition and how it impacts Stratasys and PADT. We now have some answers so we thought we would share them with you.

PADT has been involved in what is now called 3D Printing since our founding in 1994. We have seen the technology grow in popularity beyond our core engineering customer base to become a mainstream technology. The addition of MakerBot to the Stratasys family allows us to become more involved in those mainstream applications. Exciting times.

First off, the deal was a stock only transaction worth about $400,000,000, so it does not impact the ability of Stratasys to continue to invest in product growth and improvement. That was great news.

Second, it looks like for now MakerBot will be run as a separate subsidiary of Stratasys, Ltd. At first we were a bit worried about that because we wanted to interact more with the whole MakerBot universe. We soon found out that Stratasys understood this and although marketing, sales, and support are separate, there is some great cross-pollination going on.

PADT received a MakerBot Replicator 2 Desktop 3D Printer a few weeks ago and we have been playing around with it in our Colorado office. Our sales people and engineers are learning as much as they can about the system so we can better explain it to everyone we meet out there who are interested in 3D Printing.

Although we do not sell or support MakerBot products directly, we can now offer access to the MakerBot online store through a PADT link. When you purchase a printer, scanner, material, or parts after using the link, everyone knows you are a friend of PADT and we receive a small commission. We plan on using those funds to help support local 3D printer networking and education activities. And you do not have to be an existing PADT customer or located in our Stratasys sales and support territory. Anyone can purchase through the PADT link.

We will announce events, videos, and articles about MakerBot through our social media outlets and email as they get scheduled.

Last week the Rocky Mountain Region of the Cleantech Open announced the three finalists and sustainability award winner that they will be sending to the Cleantech Open Global Forum in San Jose, CA this November to compete for the $200,000 award package. The finalists worked through the regional accelerator with twenty other companies and then competed to come out on top and travel to the national finals.

Read the press release here.

As a sponsor, PADT was honored to be in attendance at Denver’s Cable Center for the 5th Anniversary event.  The best part was that two of the three finalists were companies from Tucson Arizona.  The three winners were:

  • Grannus (Tucson, AZ) as a finalist and sustainability award winner for their zero-emissions process for making nitrogen fertilizer.
  • HJ3 Composite Technologies (Tucson, AZ) as a finalist for their composite infrastructure repair system.
  • OptiEnz Sensors (Ft. Colins, CO) as a Finalist for their in-situ organic chemical sensors.

We enjoyed working with all of the applicants throughout the year and look forward to working with the finalists as they move forward.  We wish them the best of luck and are rooting for them to return to the region as one of the winners.

Final PADT Open House Held at Littleton Colorado Office

SONY DSCThis past Wednesday customers, vendors, and friends of PADT gathered at our new Littleton, Colorado office for the third and final open house for 2013.  It was definitely a little cold outside, but that did not keep people away from some good discussions, beverages, and a chance to meet other people in the area who are interested in the sort of things that PADT does: simulation, product development, and rapid prototyping.

We were fortunate to have Debbie Brinkman, the mayor of Littleton, and several council members in attendance along with representatives from the South Metro Denver Chamber of Commerce and the Colorado Space Business Roundtable.

Besides the chance to socialize, the highlights of the evening were the ribbon cutting ceremony and the tour of PADT’s new office.  As always the 3D Printers were a big hit.

Here are some pictures of the event:

SONY DSC  When the sun was still out, it was a good time to share a beer and talk about engineering and technology in Colorado.

Since this is a new office for s, the city held a ribbon cutting ceremony.  From left to right were:  John Brackney (South Metro Denver Chamber), Ward Rand (PADT Co-Owner), Eric Miller (PADT Co-Owner), Mayor Debbie Brinkman (Littleton), Edgar Johansson (Colorado Space Business Roundtable), and Norman Stucker (PADT Colorado GM)SONY DSC

Clinton Smith, Patrick Barnett, and Stephen Theron from PADT were there to meet with customers and catch up.

SONY DSCMario Vargas, PADT’s Hardware Sales manager, spent much of the evening showing off PADT’s collection of 3D printers that are in the Littleton office.

When Colorado’s attendance of 125 is added to around 50 people at the Albuquerque, New Mexico open house, 300 in Tempe, Arizona we estimate that over 475 people came to one of our events this year.  We hope to see even more for our 20th anniversary celebrations in 2014.

 

PADT on Panel for Immigration Reform Discussion at University of Colorado Boulder

The Global Innovation Forum and several other groups (see picture) put together a very informative discussion on immigration reform and its impact on high-technology companies and university research.  PADT’s Eric Miller was asked to server on the panel and share our experience with the immigration process and how the current system impacts our business.

photo

 

We learned several key things during the discussion:

  1. The need for immigration reform is a high priority item across high technology industry companies.
  2. The issues that companies have with the current immigration system seem to be consistent: not enough H1B visas, a lottery system that is often overwhelmed by a few large companies, once a year lottery, and the non-portability of a visa if the immigrant changes jobs.
  3. The Senate comprehensive reform bill actually addresses many of the concerns raised, but it is stalled in the US House of Representatives.  It may pass in pieces.
  4. There is strong consensus on most details of immigration reform, the sticking point seems to be what to do about those who are currently in the country without a visa or a clear path to one.
  5. We learned a lot about the significant problems that students and professors face when they are studying/working in the US on an educational visa. It especially impacts their family.

This group seems to be trying to advocate a common sense approach to fixing our immigration system.  A very interesting meeting and it was an honor to participate.

We encourage all of you to engage in such a discussion and change the dialog to think of immigration comprehensively and update our system so that the US can continue its leadership in the areas of innovation and research.

And in the end: we know that process of immigration is hard and stressful, so it is better to check your address registration with https://www.us-mailing-change-of-address.com/blog/change-of-address-texas/, so you can get your documents at the right place and time.

/HBC: One of Those Little Known Commands

The other day we received a tech support call requesting a way to remove the space between the element faces on a pressure plot.  He wanted this so that he could get a contour plot without seeing the contours of the elements on the back side of the part. So I built my trusty test block and applied a pressure. By turning on the pressure load symbols with  the /PSF command, also under PlotCrtls > Symbols, you can get plots like this.

image

Face Outlines (/PSF,1,1)

 

image

Arrows (/PSF,1,2)

 

image

Contours (/PSF,1,3)

Of course the customer was using this last contour plot option, but as you can see below, if you have pressure on both sides of the model, then the backside pressures show through the gaps. The plot can get a bit confusing. So after some digging, starting with the /PSF command, and not finding any reference on how to change the plot behavior, I asked around if anyone else had a way to do it, other than my first inclination which was to write a macro. So as I reverted to creating a macro, to do what should be a simple task, I thought, “No, there HAS to be an easier way.” Of course there is.

image

The one thing I’ve learned over the years… Well, yes, I’ve learned more than ONE thing, but I’m trying to make a point here… The one thing I’ve learned over the years, is that no matter how much I learn, there is always someone who know more than me.  So I asked Sheldon! (Not the Sheldon on Big Bang Theory; ANSYS, Inc’s very own Sheldon Imaoka.) I thought, “Surely he will know some undocumented command to save me time.  It took him all of three minutes to get back to me with the /HBC command. It is a fully documented, but seldom used, command that is hidden in the recesses of the Command Reference that determines how boundary condition symbols are displayed. When turned on, it will “use an improved pressure contour display.” So you go from the picture on the top, to the picture on the bottom.

imageimage

So I learned two new things. One is the /HBC command can give you nicer looking plots. The other, and even more useful thing, is to click the links on the help page at the upper right corner.

image

For if I did, I would have found the /HBC command on my own.

image

It looks like I need to sit down with a nice cup of hot chocolate* and the Command Reference and just scan the listing for commands that I don’t recognize and learn what they do.  Oh, what I go through for you people. Well, I’ll just make sure that it’s really good hot chocolate*.   I’ll write a new post from time to time on cool commands I find useful.

Have a great day!!!

*It’s 85 degrees here this week and I really meant iced tea, but I didn’t want to rub it in. Smile

Summary: Are you sure? Part 2

So I didn’t have to have the “Are you sure?” question with Eric this time and I didn’t bother triple checking the results because indeed, the Ivy Bridge-EP Socket 2011 is one fast CPU! That combined with a 0.022 micron manufacturing process  the data speaks for itself. For example, lets re-dig into the data for the External Flow Over a Truck Body with a Polyhedral Mesh (truck_poly_14m) benchmark and see what we find:

STEP OUT OF THE BOX, STEP INTO A CUBE

PADT offers a line of high performance computing (HPC) systems specifically designed for CFD and FEA number crunching aimed at a balance between cost and performance. We call this concept High Value Performance Computing, or HVPC. These systems have allowed PADT and our customers to carry out larger simulations, with greater accuracy, in less time, at a lower cost than name-brand solutions. This leaves you more cash to buy more hardware or software.

Let CUBE HVPC by PADT, Inc. quote you a configuration today!

 

PADT at University of Denver Industry Day and Lecturing at Univerisity of New Mexico

IndustryDay-DU-PADT2It is a busy couple of days for PADT and Academia.  Jeff Strain is visiting with customers in Albuquerque and popped in to the “Finite Element Methods in Solid Mechanics” class at the University of New Mexico to give a talk on the ANSYS products and give some  on real world insight in to using finite elements in industry.

We were also happy to attend Industry Day at the University of Denver’ School of Engineering & Computer Science.  It was another great opportunity to interact with students,  give them some real world feedback, and meet with other technology companies in the area.

 

Quick Tip: Tool for Putting LaTex Equations in PowerPoint

I’m not a big fan of LaTex. That is probably more a reflection of the fact that I don’t have an advanced degree and didn’t have to write a dissertation than anything else.  But one thing that is worse than LaTex is the equation editor in PowerPoint. If you are like us, you use PowerPoint as your primary reporting tool and dread putting equations in.

Matt Sutton was doing just that the other day and thought “there has got to be a better way!”  He found one. A tool called IguanaTex.

http://www.technion.ac.il/~zvikabh/software/iguanatex/download.html

There is not much to it, it is free, and it works well.

Making APDL Parameters Available in the ANSYS Parameter Manager or DesignXplorer: Prep, Solve, and Post

This is one of those questions that comes up every once in a while that is not so obvious at first glance, but that is simple once you understand how ANSYS Mechanical interacts with ANSYS Mechanical APDL.  After a couple of email exchanges around a tech support question, we thought it would be good to share with everyone.

Before we get started, if you need a refresher on Command Objects in ANSYS Mechanical, the way in which you send APDL commands to the ANSYS Mechanical APDL solver, here is a seminar from a couple of years ago that covers the whole deal:

The basic problem is this: you have an APDL script you execute as a command object that does some sort of model interrogation or stores the result of some calculation, and you want to use that parameter in the parameter manager or in DesignXplorer.  If you look at the details view for a command object you will notice that it only supports input parameters: ARG1-ARG9.

image

If you look at the example (silly) macro you will see that it:

  1. Grabs component (named selection) END1
  2. Figures out how many nodes are attached to END1 (NMND)
  3. Takes ARG1 as the total load applied load
  4. Calculates the per node load by dividing the total load by the number of loads.
  5. Applies that per node load
  6. Reselects all the nodes

If I want to know how many nodes I put the load on and what the per node load is I’m kind of stuck here.  Any command object you add to the tree above the Solution branch only allows input parameters.

But a command snippet applied in the Solution branch is different, it allows you to pull parameters back and share them through the parameter manager.

When you first insert a command object you only get input parameters (ARG1-ARG9) as usual, and an empty section called “Results”

image

The way you get result parameters, or what I think should be called “Output Parameters” is you create a parameter in the command object’s APDL script that starts with “my_”  When you click outside the text input window the program parses you script and if it finds any “my_” parameters in the text, it sticks them in the Results section:

image

Note, the default is “my_” but you can change it n the “Output Search Prefix” line in the Definition block.

Initially they will show up pinkish because the model has not been run and they are not defined. Click on the box to make them parameters that get passed outside of the program and then run:

image

If you pop back out to the project view you will see that we now have a Parameter Set bar with both input and output parameters:

image

And if you open the parameter manager up you can see the input and output parameters:

image

This works because all ANSYS mechanical is doing is making one big batch input file for ANSYS MAPDL.  That file contains any command objects you insert into the tree and extracts any parameters that you tagged in a post processing command object for return to ANSYS Mechanical.
