Major Milestone Achieved: 3D Printing of a Full Turbine Engine

3d-printed-jet-engine

Not long ago the sages in the additive manufacturing world said "Someday in the future we will be able to print a complete Turbine Engine."  That someday is now, much sooner than many of us predicted.  Researchers at Monash University in Australia recently created a modified version of a Safron Microturbo Auxiliary Power Unit using 3D Printing.  The whole thing.  Milestone Achieved.

The best article on this amazing story is on the Melbourne Examiner page:
www.smh.com.au/technology/sci-tech/3d-printing-melbourne-engineers-print-jet-engine-in-world-first-20150226-13pfv1.html 

Turbine Engines are really the peak of machine design. They contain every nasty thing you might run into in other machines, but spin faster and run hotter.  It's hard stuff. The geometry is difficult, lots of small features and holes, and significant assembly and tolerance constraints.  Getting a demonstrator built like this is a huge deal.  As a former turbine engine engineer and a long time user of additive manufacturing, I'm amazed. 

Check out their video:

The "3d Printer" they used was a huge Concept Laser Direct Laser Melting system.  The technology uses a laser to draw on the top of a bed of powder medal, melting the medal in small pools the bind and create a fully dense part with cast like properties.  They used three different metals: nickel alloy, titanium, and aluminum.

Concept-Laser-3d-printed-turbine-enginePADT has chosen to partner with Concept Laser for our metal 3D Printing strategy, which gives us additional excitement for this sucessful project.  

Now that someone has achieved this milestone, the industry can move forward with confidence that even more can be done with metal 3D Printing.  Much was learned in the creation of this advanced device that we can build on and apply to other industries and applications. 

Much is said in the twittersphere and press about printing food or custom dog tags, but this sort of high value industrial application is where the real impact of 3D Printing will be felt. It shows that companies can develop new more efficient products in less time and that are not constrained by traditional manufacturing methods. 

PHX Startup Week Going with Tours at CEI and PADT StartUPLab

PADT_StartUpLabs-1Phoenix Startup Week has started!  One of the key events on the first day centered on tours and talks at CEI, which kikced off with tours of PADT StartUpLabs, the advanced 3D Printing facility for startups located at CEI. This was followed with CEI tours and an afternoon of talks on Medical Device startups.  Then the tours repeated for those who could not make the early ones.

There is a great article in AZ Tech Beat today covering the event and what  we are doing at PADT StartupLabs:

Space travel to startups, 3D printing without limits – PHX Startup Week – AZ Tech Beat

IMG_5445Attendance was great, with a cross section of startups, established companies, the press, and people active in supporting the startup community.  The visits gave us a change to explain how PADT is working with CEI to provide 3D Printing and design expertise to new companies at a reduced price, focusing on getting them over the early stages of product development quickly and effectively. 

Right now PADT StartUpLabs is focused on working with other tenants at CEI.  Engineers from PADT hold regular office hours to answer questions about 3D Printing and product development.  Clients can also set up a consultation with anyone on our staff to talk about simulation, product design or test, quality systems, or manufacturing. The goal is to eventually expand these services to a broader audience. 

This week's events are being followed closely on the twittersphere: #PHXStartupWeek, #yesphx. Or if you are middle-aged like me and use Facebook, like Phoenix Startup Week.

aztechbeat-padt-startuplabs-1

Startup Week is still going and there are many more informative events. Check out the website to learn more and follow AZ Tech Beat's feed as they cover things to see what happened. 

We hope to run in to lots of you at upcoming events!

Not in Phoenix?

Many of you who read this blog are not from the Phoenix area. You may be wondering "What, a vibrant startup community? I thought Phoenix was old people and nutty gun-totting right-wing nut-jobs?"  Well, we certainly have a few of  those but since WWII when large aerospace and electronics companies moved to the valley, Phoenix has been a major high-technology hub.  It is an easy place to start a business and has all the resources and talent to be successful.  PADT has been helping startups in the area for over 20 years now, and we continue to see a steady increase in the number and diversity of new companies that we interact with.  So don't believe what you see on the news, this is a vibrant, high-tech place with great people and a business friendly outlook, affordable housing, and weather that doesn't force us to spend the morning shoveling out our driveways.  

Put 3D Simulation Results into 3D PDF with VCollab

VCollab_Shaded_Logo_FinalPDF has become a great, versatile format for sharing electronic documents. But engineers doing simulation were stuck with only being able to include 2D images in their PDF files. With the release of a new Plugin for VCollab Professional, you can include 3D model and result plots right in your PDF files.  A great way to archive, a great way to share.

You can see the results by checking out these two examples:

Here is a small example of a car front: vcollab-3dPDF-example-carfront

And here is the full car: vcollab-3dPDF-example-car

You can read the full press release here.

  vcollab-3dpdf-airplane1    

PADT uses VCollab to convert our CAD geometry and simulation results in to smaller, portable formats that can be imbedded in to PowerPoint, Word, websites, portals, PLM/PDM systems, etc…  It is a great way to view complicated data without having to fire up the full simulation tool.  And the files are much smaller than a full result file, so it also is a great way to get key results off of a remote server and interact with them quickly and efficiently.

Now with 3D PDF support the end user doesn't even have to have a Microsoft Office product or be on the web, they can just view it in their Adobe Acrobat reader.  If you are interested in trying out VCollab to make 3D PDF content or for any other application, contact us at sales@padtinc.com or call 1.800.293.PADT or 480.813.4884. We can arrange for a demonstration over the web, provide you with a trial copy, and work out the best configuration for your needs. 

Stratasys Platinum Partner Status Achieved by PADT

  Stratasys_PLAT_Partner_2015

A lot is going on in the various sales groups at PADT after having such a strong 2014.   We are very pleased to announce that the latest result of outstanding efforts across the board is PADT's new status as a Stratasys Platinum Commercial Partner. Stratasys, Ltd (SSYS), the leading provider of Additive Manufacturing (3D Printing) systems, designates only the best of their reseller channel as Platinum Partners. To obtain this highest level, PADT not only had to meet aggressive sales goals, we also had to make significant investments in resources and people.  In 2014 we exceeded those sales goals by 25% and we opened up a fourth sales and support office, located just south of Salt Lake City in Murray, Utah. 

Here is a pixture of our Additive Manufacturing Sales Manager, Mario Vargas, with one of PADT's principals, Ward Rand, pointing out our latest addition to our "wall o' awards."

  PADT-Stratasys-Platinum-Partner-Award-2015

You can read more about this on our press release here.

PADT has been selling Stratasys equipment for over a decade, and we have been using their systems for over fifteen years.  We have seen them go from a few basic systems to a full offering of solutions from desktop hobby solutions to full production manufacturing centers. This year the team was able to help more customers find the right Additive Manufacturing system for their specific needs. In fact, many of the systems we sold in 2015 were additional machines or upgrades to current machines, showing strong customer satisfaction with Stratasys solutions.

We could never have achieved last years success and Platinum status without a fantastic team. Our sales professionals, application engineers, field service engineers, and support staff all strive to provide the highly technical win-win sales experience that PADT has become known for. They truly believe in this technology and are truly enthusiastic about finding new and better ways for our customers to apply it.

Those customers also deserve a heartfelt thank you for being such a pleasure to work with.  Every day we get to interact with the full spectrum of users, from the preverbal garage startup to major aerospace corporations; and everything between.  They teach us something new every day and we are always proud of the value that Stratasys and PADT are able to deliver to their product development efforts. 

If you want to learn more about 3D Printing and why Stratasys systems have continued to outsell the closest competitors for years, please contact Kathryn Pesta at 480.813.4884 or kathryn.pesta@padtinc.com.  She will put you in touch with one of our sales people located in your local area.  Or you can visit www.padtinc.com/stratasys to learn more about the technology. 

 

PADT’s ANSYS Sales Team Celebrates Sales Record for 2014

2014 was both a challenging and rewarding year at PADT. One area of the company that achieved success last year was the ANSYS Sales team.  Lead by Bob Calvin, our account  managers Oren Raz and Patrick Barnett worked with the support of our technical team  throughout the year to help our customers find the right solution for their simulation needs. All that hard work resulted in a record year of sales for ANSYS products by PADT.

A big "Thank You" needs to go out to all of our fantastic customers who make selling and supporting this tool such a pleasure. Our success is a direct result of the success that they are having in the application of ANSYS, Inc. technology to improve their products and their product development process. I know that sounds kind of "salesy" but it is true.  We keep selling more of this stuff for one simple reason, it works. 

And making it work is also the job of our technical support team, our engineers who serve as application engineers, and the business support staff that takes care of the details. 

 This week we were lucky to have Bob Thibeault, the new ANSYS Director North America Channel, and Clark Cox, the ANSYS Channel Account Manager, visit Phoenix and we were able to get a picture with them as we placed our 6th annual sales achievement medal on our "wall o' awards."

PADT-2014-ANSYS-Sales-Achievement-Award
2014 Accomplished – Putting the medal on the wall

Things are already off to a great start for 2015 and we hope to be working with even more customers as we help them explore new and profitable ways to apply this technology. 

Seminar Info: Designing and Simulating Products for 3D Printing

Note: We have scheduled an encore Lunch & Learn and companion Webinar for March 23, 2015.  Please register here to attend in person at CEI in Phoenix or here to attend via the web.

ds43dp-1People are interested in how to better do design and simulation for products they manufacture using 3D Printing.  When the AZ Tech council let us know they had a cancelation for their monthly manufacturing Lunch and Learn, we figured why not do something on this topic, a few people might show up. We had over 105 people register, so we had to close registration. In the end around 95 total people made it to the seminar, which is more than expected so we had to add chairs. Who would have thought that many people would come for such a nerdy topic?.

For an hour and fifteen minutes they sat and listned to us talk about the ins and outs of using this growing technology to make end use parts.  Here is a copy of the PowerPoint as a PDF.

We did add one bullet item in the design suggestions area based on a question. Someone pointed out that the machine instructions, what the AM machine uses to make the parts, should be a controlled document. They are exactly right and that is a very important process that needs to be put in place to get traceability and repeatability.  

Here are some useful links:

As always, do not hesitate to contact us for more information or with any questions.

If you missed this presentation, don't worry, we are looking to schedule a live/web version of this talk with some enhancements sometime in March.  Watch the usual channels for time, place, and registration information. We will also be publishing detailed blog posts on many of the topics covered today, diving deeper into areas of interest.

Thank you to the AZ Tech Council, ASU SkySong, and everyone that attended for making this our best attended non-web seminar ever.

Design and Simulation for 3D Printing Full House

The Full Power of SpaceClaim Engineer – Now Available from PADT

SpaceClaim-1We have been using SpaceClaim with ANSYS Workbench for about four years now, and we always liked it. Then it came as part of the Geomagic Spark tool and we got more excited.  This was a powerful geometry creation, editing, and reapir tool that was saving us time all across PADT.  The, when ANSYS, Inc. purchased the company SpaceClaim we got realy excited.  So excited that we decided to become a reseller of the full product, and not just the ANSYS or Geomagic tools.  The addition of a module for working with STL files sealed the deal and as of the begining of the year we are offering all flavors of SpaceClaim to our customers.

The official press release can be found here. You can learn a lot about the product by visiting the web page.

To get started learning about why we love this program so much, check out this video showing the new features in the latest version:

Then go visit their YouTube channel and watch videos that may be of special interest to you.

Or, contact us here at PADT and we would be happy to share with your our enthusiasm for this tool.

Deflategate Update: ANSYS Simulation Shows it Really Does not Make a Difference.

There is still more debate going on about the deflated footballs that the New England Patriots used in their playoff game. "Who Deflated Them? When? Were they acting on orders?"  But no one is asking if it makes a real difference.

Enter ANSYS simulation software. Using the newest ANSYS product, ANSYS AIM, the engineers at ANSYS, Inc. were able to simulate the effect of lower pressure on grip. It turns out that the the difference in pressure only made a 5mm difference in grip. No big deal.  

Being a Multiphysics tool they were able to quickly also run a flow analysis and see what impact drag from "wobble" had on a pass.  A 10% off axis wobble resulted in 20% more drag, that is a few yards on a long pass.  Their conclusion, throwing a tight spiral is more important than the pressure of the ball.

Turkey, Team Building, and Spaghetti Towers: PADT’s Turkey Bowl 2014

IMG_0121

[EDITOR’S NOTE:  This was written some time ago and was set to automatically go out. But I just found it stuck in the “pending” folder.  So late, but here it is]  

It has been a great 20th anniversary year for PADT.  And we decided to close it out with some fun.  Now, if you know engineers, getting them to take part in any team building event is tough. And many of our employees came to PADT to get away from such things. The phrase "team building" causes a Pavlovian eye roll.  As we discussed options for November, we looked at a lot of activities. When we settled on doing an event that not only involved teams, but also color coded shirts, puzzles, and (gasp) a lean towards being healthier I said "we should try it, but it probably won't work" and hoped to be proven wrong. Even with the help of the great folks at Physix, I didn't have high hopes. But you don't know until you try.

I was proven wrong. 

Kickoff: Halloween and Pumpkin Launching

We started with a kickoff event on Halloween, which was nice enough to be on a Friday this year. In the past we have carved pumpkins and built a dry-ice pumpkin mortar.  This year we fed everyone to get them in a good mood and then put them in teams.  After some trivia contests we moved over the the first event – a pumpkin slingshot.

We finished up the kickoff event with rules and a list of ways to get points:  go to lunch with team mates, go for a hike, attend a class at Physix, get a fitness assessment, lose weight, answer the weekly quiz, and walk.  The easiest way to get points was to keep track of your step count.  

Three Weeks of Getting Points

The next three weeks were fun. Different teams approached things differently. Some opted to lunch together, often.

yhsfgn yhfgsdhsfh yfghdfhg ttertfg ttasn hhhhhhhhhhhhhh hhhhhhh ffffas fasdftrt fafrtyy asdfgg yujghj

Others did a fitness assessment or attended a class.  One team even tried to take a hike… on Photoshop:

ffffffffffff

Funny how their picture on Camelback Mountain looks a lot like their lunch picture…  

After a bit of a kerfuffle on Body Mass Index results from the fitness assessment, we held a brown bag seminar by the lake.  The reason why Physix is a great match for PADT is that their approach to health is science and fact based.  No chakra alignment here.  So Shannon came armed with statistics, studies, and fancy measuring devices with dials on them that we could write down numbers from.

yyyy 

There was also a weight loss competition.  Points for every pound lost. There are and will not be pictures from that portion of the event. But we can share that some people dropped a few pounds over the three week period, and some more than a few.  

Turkey and Contests 

At the end of the three weeks we gathered together again to take part in our annual Thanksgiving Feast, and compete to win some additional points for our teams.

lkasd;kifa

We started with a plank contest. Expecting 5 or so people to participate, maybe one from each team. Everyone gave it a shot:

IMG_4701

Most people lasted a minute, then they started to drop.  

IMG_4706

A ton of people lasted to 2 minutes, then 3, then 4.  6 people were holding at 4:30.

IMG_0142

Purple had a strong showing, Renee lasting past 5 minutes.  Clinton held strong for purple.  Don, and Demola held on for Orange and Black.

ssssssssssss

In the end, Demola won a ton of points for his team, lasting past 6 minutes.  

Next we tried a relay event that involved passing a ball over our heads and taking a step, then running to the back, then passing… what was that again. It took us a while to figure it out.  In hindsight, we should have created a process diagram before the event.  

IMG_0017

But Green and Black figured it out and charged to the finish line… not even stopping when one competitor stumbled.  No one left behind, as long as they have the right shirt color.

Inside, we had a timed puzzle building event. It got kind of nasty when the teams realized that each team had two pieces from another puzzle. People get aggressive when points are on the line.  There may have been some hiding, there may have been some prying of fingers open.

feverish puzzle activity

The last event was to build a tower out of spaghetti, string, tape, and a marshmallow. Whoever got their marshmallow the highest got the points.  Four of the teams built tripods and went for height.

IMG_0097

Two teams figured out that spaghetti bends and breaks.  Blue felt that building a box was better. I guess that is thinking outside the box?

IMG_0025

But the winner was a combination of tripod and "stoutness."  Green figured it out:

IMG_0063

There was a dessert contest as well. I grudgingly mention it because my dessert didn't make it into the finals… but I'm not bitter, not at all.

dessert contest

After that we all went back to work while the PADT HR and Physix teams summed up all the points and figured out who won.  

Green, thanks to their tower, squeaked into third place:

IMG_0217 

Some were happier than others about the competition.

Second place was won by the superior team, and we would have won if my dessert had been in the finals:

IMG_0125

And the winners were the Black Team.  

IMG_0132

You have to admit, they do look pretty confident.

What we Learned 

Overall, the three weeks were a nice distraction from a very busy period.  Some people that would not have normally spent time together, did. Some people learned a bit about fitness or nutrition that they didn't know before. A lot of people walked a lot more.  

We also learned a couple of lessons:

  1. You can have a positive and constructive team building event at a company that is kind of wired to go against such corporate group-think activities.

  2. Not everyone wants to participate. That's OK and it is no reason why those that do can't have fun.  And you can find small ways for people to take part.

  3. Some people are REALLY competitive. 

  4. The average core strength at PADT is stronger than we thought.

  5. The breath mints we got to combat coffee breath are 50 calories, and the average person has to walk around 500 steps to burn them off. 

  6. If you don't take these things too seriously, they can be fun and a nice break.

  7. PADT's employees are clever. They tried to get points for waking up in the morning and mouse clicks.  You have seen the Photoshop picture. They also wanted to pass off the PADT Medical skeleton as Don Pegg after his diet.  It didn't work.

6hgdf

For those of you who are thinking of doing a similar event at your company, some key words of advice:

  1. Bring in someone to help that is a good fit for your culture. Don't try and fit a standard or large company approach to a small or medium company.  Find someone that gets you and maybe pushes your organization a bit further than you would push it on your own.

  2. Keep it short, keep it simple.

  3. Don't let the negative people drag it down. You will have some people that this is not a good fit for. If you try and please them, they will still be unhappy and it will lesson the event for others.  Just accept that not everyone will be on-board and move on.

  4. Place your tongue firmly in your cheek.  If you take these things too seriously, they will fail.  Make some fun of yourselves and the activity, it takes that edge off.

If you do it right, you might even get engineers to touch each other.  

The Real Revolution in 3D Printing: It’s Normal

3D-printed-printerReading through my email this morning I saw an update from the "maker" site Instructables and I glanced at it quickly: "floating bed, how to make a sword, that's cool, 3D printable printer, folding chair charcoal forge, what?, parachord hammer holder, just buy one, duh, blah, blah, blah how do people have time for this… wait, 3D printable printer?" CLICK.  

So this 17 year old kid used his 3D Printer, an arduino board and parts he scrounged from old DVD drives to make a 3D Printer. Read about it here.  This kid, wootin24, designed and built an X, Y, Z positioning device that could be fited with a dremel tool to be a CNC machine, or an extruder to be a 3D Printer.  No CAD experience, no formal engineering training, just a smart person.  And the ad that popped up on the side of the how-to this kid wrote was for a Dremel 3D Printer, available at Home Depot. Not some kickstarter funded rehash of an opensource printer, Dremel. The big guys.  As I was feeling bad about how I spent my time when I was 17 (I'm not going to go there but I never did become a the backup bass player for Rush nor did I get a second date from T—–) and starting to worry about how systems from very capable companies like Dremel will impact our sales of Stratasys equipment, I realized that the true revolution in 3D printing happened and most of us involved day-to-day in the industry didn't even notice.  

3D Printing is Now Normal

When a revolutionary technology comes out there is a lot of hoopla and press. Tons of people start jumping on the bandwagon and your Aunt's friend in Topeka is sending you links on Facebook about 3D Printing and how it is "going to change everything."  Do not get me started on how 3D Printing is not new, we've been doing it at PADT for over 20 years, and certainly do not ask about the "3D printed gun.  The false-newness and fear-mongering stories are what the mainstream press picked up on. The good news is that the hype got the word out. And then smart people like this kid and the engineers at Dremel said "hmmm, that is useful. I can do something with this" and boom, the real revolution happened.  

After all these years this tool that was really a special tool used when needed, has become just another screwdriver in the toolbox.  A standard part of the process it is something most engineers understand well, and a majority of non-engineers are aware of. When we first started showing people our SLA machine back in the 90's they would either not understand what they were looking at or become flabergasted and amazed, treating it more like a magic box than a fairly simple additive curing system.  Now when we give tours we hear "that one looks like the one we have in our office" or "oh yea, an Objet, I'd love to trade my older system in for one of those." And the dreaded "oh, we have three of these in our robotics lab at school, do you have anything interesting?"  

3d-printers2
Amazon now has a section for all the 3D Printers they sell, just like headphones or video games.

So What

There is a lot of power in 3D Printing.  That is the real reason why the technology has blossomed as it has.  The power of 3D Printing is that it lets you make physical objects without special equipment or knowledge, the laser printer of manufacturing. However, as long as the tool is treated as something to be used in special cases or as a mystical new magic bullet, it will not be used correctly.  Now that it is mainstream, the use of additive manufacturing becomes mainstream and the power it brings to the table can be fully realized.  We see this every day at PADT. Product managers have "3D Printed Prototypes" as a standard line item in their budget templates.  Customers are increasingly talking about going back to their current product lines and identifying parts that are machined, injection molded, or cast and determining which can be replaced by 3D printed parts.  And most importantly, the supply chain and quality people are sniffing around and starting to make paperwork to control and manage 3D Printed components.  

As proponents of the technology since the early days, we could not be happier than when we see a check box for "Created with additive manufacturing" on a quality form. When it becomes part of the bureaucracy, the revolution has truly happened. 

Customer in the News: Soitec Sets Record for Solar Cell Efficiency at 46%

soitecWe noticed that customer and neighbor Soitec Phoenix Labs had a great writeup in the AZ Republic. Their substrate technology was used to make a multijunction solar cell for use with conentrated solar, delivering an amazing 46% efficiency. The standard right now in the mid to low 20% for single junction, the most common technology available. The article actually does a pretty good job of explaining the technology, why Soitec has something special, and some insight into their LED technology as well.

A big congrats to the team and we can not wait to hear when you break 50%!

They have a great video on their CPV efforts on their website.

Soitec is a french company that purchased GaNotec a few years back.  Their Phoenix Labs is across the lake in the ASU Research Park in the ASU MacroTechnology Works building and PADT has provided a variety of services to the company since it started as GaNotec.  We have worked with many of their employees at other Semiconductor Equipment companies before GaNotec was founded. 

Congrats to everyone!

Press Release:

Dedicated 3D Scanning Added to Round Out PADT’s Scanning Solutions 

PADT now has a full time engineer and equipment dedicated to providing 3D Scanning services to customers.  Coupled with the sales and support of 3D scanners and software, PADT can now offer a complete solution to its growing number of scanning customers. 

Tempe, AZ – January 8, 2015 – Phoenix Analysis & Design Technologies, Inc. (PADT, Inc.), the Southwest’s largest provider of simulation, product development, and rapid prototyping services and products, is pleased to announce the addition of complete 3D part scanning to our services offering.  Based on growing customer requests, PADT has invested in equipment, software, and personnel to provide a dedicated resource in this area.  The company has been providing scanning as a service for many years, but on a part time basis when staff was free and customers could not find another resource.  PADT’s 3D Printing sales team has also been selling scanners and scanning software for over three years.  Bringing someone on board to focus on this critical need in product development was the next logical step.



3D Scanning is used by engineers to take a part in the real world and measure it accurately in order to get a model of the part on a computer.  This is done using a variety of technologies including lasers, patterned light, and high resolution pictures. The technology is used in product development to capture geometry of existing parts to reproduce (reverse engineering) them or design parts that attach or interact with them. It can also be used to inspect manufactured parts.



Ademola Falada joins our team from Minnesota where he worked for a scanner manufacturer, CGI, for two years after graduating with an engineering degree from the University of Minnesota.  He brings extensive knowledge of scanning equipment and the scanning process.  Since joining PADT in the late summer, he has been providing limited services to our existing customers as he builds up our scanning capability and puts everything needed to provide a world class service in place.  He will be assisted by engineers and technicians that have been providing scanning on a part time basis in the past.



“We are now ready to open our doors wide to customers who need accurate, timely, and useful scanning of their parts.” Commented Rey Chu, one of PADT’s owners and the Principal responsible for the company’s manufacturing services. “We never felt that we could deliver the level of service that customers expect from PADT until we had enough equipment and a dedicated engineer. We are there now.”



The scanning lab consists of two CGI Cross Sectional Scanners for high fidelity scanning of complex plastic parts with internal features, a Geomagic Capture blue light scanner, and a Steinbichler high resolution blue light scanner currently under evaluation. This combination of equipment is matched with the full suite of Geomagic scanning software to provide inspection data, cleaned point clouds, tessellated solids (STL), or usable CAD models. 



Customers who are interested in having parts scanned, or who want to learn more about the service, can contact the team at 480.813.4884 or scanning@padtinc.com

ANSYS 2015 Hall of Fame Announced – Los Alamos National Labs and SynCardia Models are Finalists

2015-hall-of-fame-header-closed

Every year for a while now ANSYS, Inc. has chosen models made by users of the ANSYS software tools for their Hall of Fame.  This year had some very cool models across CFD, Structural, and Electromagnetic – including some great Multiphysics applications. Visit the ANSYS website to see all the winners here.

The three commercial winers of "Best in Show" were varied but powerful examples of how simulation can be used to improve performance and reliability of products:

 best-in-show-2015-ansys-hall-of-fame

Andritz Hydro used ANSYS Mechanical to model their assemblies to see if replacing welds with bolted joints would reduce weight and cost while keeping reliability.  They used sub-modeling, bolted joints, and contact.  

BRP used ANSSY CFX, ICEM CFD, and Mechanical to capture the forces caused by cavitation on their outboard marine engine. This engine pushes a boat at 75MPH (!!!) through the water, so yes, they get cavitation.  They used ICEM CFD for meshing, CFX to predict the cavitation and capture the cavitation loading, and Mechanical to see how the loading impacted the gear train and shafts. They were able to obitmize the desgin quickly using this process.

Spinologics used ANSYS Mechanical APDL to model the process of using a rod to straighten a deformed spine (scoliosis). They use the scriptability of the APDL to automate the creation of the models.  Very cool stuff.  Check out the video on the link.

We also want to mention two customers that were involved as Finalists.  

syncardia-heartSynCardia is often mentioned in this blog because, well, they make a frick'n artificial heart that saves lives every day.  We modeled an early iteration on the heart as a multiphysic problem probobly 5 or 6 years ago, it could have been longer ago. More recently Stony Brook University and the University of Arizona did a much more detailed model in ANSYS Fluent that looks at not just pressure and velocity, but Platelet dispersion patterns in the artificial heart.  Check out the video here:  https://storage.ansys.com/hof/2015/video/2015-stonybrook.mp4

2015-lanl-bgLos Alamos National Labs is another long time PADT customer and we were fortunate enough to be involved in the study that was recognized as a finalist. They used ANSYS Fluent to model something called vortex-induced motion or VIM in off-shore oil rigs.  Basically waves hit the platform and create these big swirling vortices.  These in turn put loads on the structure that can sometimes be very large.  The purpose of this study was to find a way to accurate predict VIM with simulation so they could then evaluate various solutions. A true Fluid-Solid Interaction (FSI) and because of the size of the structures and all that turbulence, High Performance Computing (HPC) problem. We hope to publish a paper on some related work this year… watch this space for more.

 This competition is a great way to see what others are doing, and if you submit your models, to show off what you have done.  Contact your ANSYS rep to learn more or drop us a note.

 

Christmas Right-Left Gift Exchange Story: Fairy Tale Style

Left-Right-Christmas-Story-2014For our Christmas parties at PADT we generally have over 40 employees so a traditional secret Santa gift exchange takes to long. So a couple of years ago we downloaded a right-left gift exchange story from the internet and it was a big hit. We ran out of stories on the internet, so we started writing our own, usually in some sort of over-the-top style.  This year we have a cationary fairy tale. Here is how it works. 

Everyone gets their gift and forms a big circle in the middle of the room.  Someone with a strong voice reads the story and every time the world LEFT is read, everyone passes the package they have to the left. Every time the world RIGHT is read, everyone passes the package they have to their right.  You should pause a bit at each LEFT/RIGHT to give people a chance to pass.

The Wooden Horse

In a village, that sits on the left bank of the river Dreamwald, there is a good and generous family, the Leftmulds. The father is the last barrel wright left in the duchy of Cornwil-o-day-leffon.  He has a wife, two gorgeous twin daughters, and a son name… Albert.  Albert was willful and spoiled.  He thought he was always right and he always wanted what he wanted right now.

One day, about right when the cows needed to come in from pasture, Albert stormed in to his father’s workshop, walked right up to his father, and said:  You have left me no choice but to go on strike.  I demand you make me a wooden horse toy right now.

“Albert” his father said “You left the door open. Please close it.”

Albert replied: “I don’t care if I left the door open, you promised me a horse and I want it now. “

His father said “I told you, when you clean the right side of the barn, and there is no mud left on the floor, and there is no hay left outside, I will give you your horse”

“I hate you!  I wish you had left me with the stork!  I’m leaving right now”

And with that, he stormed out.  All is father said was “You still left the door open my son. Something is not… correct with you”

Albert ran from the village. Right past the mill, right past the well, and right out the gate into the dark and ominous Dreamwald forest.  He soon slowed, for the run had left him out of breath. But he kept walking and walking.  Presently he noticed an old woman in black standing right in the middle of the path. He walked right up to her and said. “Excuse me old woman, but you are in my way, I would ask that you step aside right now.”

The old woman peered from beneath her hood and said “I’m waiting for you Albert. You left a wish at the wishing stone last night.  I’m here to make it right.”

“You have my wooden horse?” Albert asked, having left off the idea of getting past this women.

“I do, but you must promise to give me whatever I want. Promise right now.  “

He was left with no choice “I promise”

There was a boom and a crash and right next to Albert there was a gorgeous wooden horse. It left him breathless, and for the first time in his life, something left him speechless as well. It was more than he had hoped for.

“Is it all right?” asked the old crown.

“Oh yes” he replied “It is defiantly all right.

And then she began to cackle.  The noise left his ears ringing it was so loud. And them POOF, Albert was no longer in the woods. He was inside a hut, tied right to a spit, left spinning over an open fire.

The old women continued to cackle as she pinched his left arm and licked her licks.

He screamed “Oh no!  This is not right!  In fairy tales the little child outsmarts the old witch. You have not left me a chance to even try!”

“You looked so tasty, I didn’t think it was right to play that silly old game. I decided to just put you right on the spit and roast you right away.”

Albert began to sob as the heat of the flames became more and more uncomfortable.  He was left with a feeling of utter despair.

Then, to his left, he heard the sound of sleigh bells, then he heard the stomping of many animals. Then one of the hut doors, the one on the left, opened up and a man in a big rid suit stepped inside and pointed at the old lady.

“Ismerelda!  You have left me no choice. Yes this boy is naughty, but you are worse.  You have no right to cook him, no matter how selfish and lazy he is!”  He lifted a staff in his right hand and brought it down with a thud on the ground. A blinding flash of light filled the hut and then snow began to fall right from the ceiling.  Big, wet flakes fell right on to the witch and quickly covered her, freezing her right where she stood.  The snow also fell right on the fire, till there were no flames left.

Albert freed his right hand, then his right ankle, and then untied his… other arm and leg.

“Thank you Santa! I thought I was left for dead!”

As the old man walked to the other door in the hut, the right door, he turned and said.  “Don’t thank me little boy. Thank your good parents and sisters. When you left them, you left them heartbroken and they asked for my help.  So I came right away and did what I could. Let this be a lesson to you.  You need to learn Wrong from Right!”

And with that, he left the hut, jumped into his sleigh, flew away, and left Albert with nothing but his thoughts.

In Memoriam: Dr. Mark Johnson

Mark_Johnson_PADT_Equations
A picture of Mark in his office at PADT. The equations on the white board were not put there for the picture. This was taken after a meeting where he and members of his team solved a tough rotor dynamics problem for a customer.
It is with incredible sadness that we must inform you that our friend and co-owner of PADT, Mark Johnson, passed away on November 25th from complications due to melanoma. He was with his wife, resting comfortably when he left us. This is a huge loss to anyone that ever knew Mark.

He joined PADT in the early days with the goal of building the company’s product development capability.  His focus and the focus of his team was using engineering to make the world a better place.  They did this directly through their work in alternative energy and medical devices and indirectly by helping companies from a wide range of industries.  There are hydrogen powered cars and buses today humming down the street using pumps and blowers that were Mark’s creations. Doctors are using devices every day to treat patients that Mark helped to design and test.  He also participated in the Startup and Medical Device engineering community in Arizona, serving as a judge, mentor, and board member across multiple organizations.  And as a co-owner of PADT, he helped direct the company, contributing strongly to our culture and reputation in the community.

Before joining PADT, Mark had a similar impact at Garrett (AlliedSignal, Honeywell), The University of Arkansas, and Ballard.  Few people in our industry had such a strong understanding of engineering fundamentals and his ability to apply that basic knowledge to help customers across industries will be sorely missed.

Outside of work, Mark was a loving father and husband, who always took time to be with his wife and two children.  Those of you who knew him outside of work know how important they were to him, and he to them.  

Since his passing many people have asked how they can honor Mark or share their thoughts on him.  We are recommending that those who wish to honor him simply follow his example.  Look for the good in people, help others when you can, and always ask questions.  Mark was a master questioner and often answering those questions revealed more to the person he was asking the question of than anyone else.  He often began meetings with new customers and partners with a simple statement: “I want to warn you, I like to ask questions, lots of questions.”

In that this blog is mostly read by people in technology, the best way you can honor his memory is to carry on his mission of using technology to make the world a better place. Help a startup, develop a more efficient system, commercialize a new technology that improves the lives of the less fortunate, enhance patient care, or help to explore and understand our universe.  There are so many ways that those of us involved in engineering and science can make a huge difference, just as Mark did.
