We are creating this blog posting for one simple reason: As we reflect and celebrate twenty years of being in business, we want to hear from our customers, vendors, partners, and friends. What would you like to share with the world about PADT? A story? An observation? Even a criticism. We want to know what people think about this company with the funny FLA name. Please leave your thoughts in the comments below, we can’t wait to hear from everyone. This is the first of many blog/social media posts that we will be sending out as we reflect and celebrate the past 20 years. All will be tagged with #padt20.
Wohlers Associates just blogged their list of the top news stories for 2013 in 3D Printing. It is worth a read to look beyond the hype we have seen this year and focus on the stories that will be having an impact in the future: http://wohlersassociates.com/blog/2014/01/top-3d-printing-developments-in-2013/ As a Stratasys distributor and provider of additive manufacturing services, PADT can attest to the importance of the stories listed. The first one, the GE Fuel Nozzle, had an especially significant impact on the world of commercial additive manufacturing, especially with the Aerospace customers we work with. In many ways, GE’s move was the tipping point for metal additive manufacturing and for companies to really look at AM as an end part manufacturing solution. 2014 is already shaping up to be a big year. We expect to see consolidation and a weeding out in the consumer and prosumer 3D printer market, better material options across all of the technologies, and more adoption of the technology in new industries and applications. Wholers Associates has been consulting in additive manufacturing for over 27 years and is PADT’s go-to resource for what is really going on in the AM world.
This Part 1 of 2 video shows you the first half of a multiphysics simulation using the low-frequency electromagnetics tool ANSYS Maxwell to do an eddy current analysis. Part 2 will involve taking the results of this analysis and transferring it to perform a thermal-structural analysis using ANSYS Mechanical.
WE ARE HIRING! PADT is starting 2014 off strong with lots of work ahead of us. One manifestation of this is that we are hiring for four positions, including two new positions that we just opened up this week. Please take a look at our openings and see if they are a good fit for you, or someone you know. We have posted them in the usual places but some of our best employees have been found by word of mouth and recommendations. You can find all of our openings at any time on our website at: www.padtinc.com/about/careers.html IT Support Engineer
As a company focused on computer aided engineering, PADT has significant computer and network infrastructure. With the recent growth in sales of our line of CUBE HVPC computers for simulation users, growth in business across our company, and a new initiative that we will announce this spring, our IT staff is stretched thin. Read the job description to learn more and apply yourself, or please pass this along to anyone you think might be a good fit. This is a great chance for an experienced and talented IT professional who may be at a large company, to move to a small company environment but still work on leading edge technology.Sales Executive, Additive Manufacturing, Utah
We are in need of a new salesperson to represent Stratasys additive manufacturing (3D Printing) systems in Utah. PADT has been laying the foundation for success in the state for a few years now and we are seeing strong potential sales for 2014, we just need to right person to keep growing the territory and to close the existing pipeline. Learn more about becoming part of this revolutionary change in manufacturing by learning about the job here.And don’t forget that we still have two other openings from the end of last year. We have some good prospects on both but we were so busy that we did not have time to really act on them. So there is still time to get new resumes submitted:
This video shows you a new capability in ANSYS v15.0 that allows multiple parts to be simultaneously meshed on multiple CPU cores…with no additional licenses required!
Another year is winding down to a close and PADT’s Arizona staff gathered in Chandler for our annual holiday party. It is always nice to step outside of the cubical and talk with co-worker’s spouses, employees you don’t get to talk with at work, and even with the people you do spend all day with, but in a festive setting. We had already had dinners in Albuquerque and Denver, so it was now time for the bulk of the company to celebrate and reflect. 2013 has been a great year for PADT. We saw good growth across all of our businesses, doing more business with existing customers and adding a number of new customers. Our core Simulation, Product Development, and Rapid Manufacturing business all so new and exciting growth. Some highlights include:
- Growing sales of Flownex for thermal-fluid simulation and CUBE systems for HPC
- Several key new ANSYS, Inc. product customers have joined our user community
- An explosion in interest in 3D Printing and the line of systems that PADT sells that resulted in a record number of new customers.
- We saw significant growth in Product development with several large jobs started and a few others completed. A typical project was the SPOT Gen3 Satellite GPS Messenger.
- The recent merger between Stratasys and Objet enabled PADT to begin offering PolyJet additive manufacturing systems.
- We opened an office in Albuquerque, New Mexico, our second satellite office. We also moved into a larger facility in Littleton, Colorado.
For 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 may have gone way over the top with a SciFi story that involves an alien scouting party visiting a new planet. I got a little carried away and it is a bit long. If you have never played this game before it is simple. 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 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. This year I also added a twist. When you use the word TURN, everyone needs to spin 180 degrees. Added complexity can make it more fun… or not. We hope you get as many laughs out of it as we did. You can find our Film Noir style story from last year here and a trashy Romance style story here.
Winter’s Night RediscoveredLeft to their own devices, the Zalaks will in general, wonder right around the galaxy. Captain F’Tool G’K'Right and his right hand man, and nestmate, leftenent P’Turn N’Tuk were lucky enough to have a job where they were paid to wonder around the galaxy. It left them both with a sense of true satisfaction and a feeling that could only rightly be described as joy. “P’Turn, where are we Right now?” asked captain G’K'Right. “Right now… let me see” muttered N’Tuk as he stared as his navigation console. “We are approaching an inhabited planet referred to as Earth in the dominant language.” G’K'Right asked: “Technological Status?” “They appear to be right in the middle of the standard computational revolution, having just left a short nuclear period wherein the majority of the planet appears to have been left untouched by thermonuclear conflict” answered leftenent N’Tuk. “Where should we land for our initial investigation?” Captain G’K'Right tapped his right temple with his right foreclaw. “hmmm…. This should not be left to chance, I think we should land in an uninhabited spot, right here” he said pointing at the nav screen with the same right foreclaw “right on top of the planet on this ice cap.” “Right sir!” responded N’Tuk. “Turning on landing engines, setting course left 237, right 124″ The ship shook violently, left to right, forward to aft, as it descended through the atmosphere of the planet. Soon the ship slowed and stopped right above a huge ice ridge, looking down into a valley that should have been just snow. The crew looked at the right view screen, which showed sensor data. It registered the expected uninhabited snow covered valley. But right there in front of them, on the left view screen, which showed a visual image, they were left with no doubt. The valley was filled, from left to right, with a sprawling village. The view left the captain stunned. “Turn off the landing engines and set down right here. Leftenent N’Tuk, we are left with no choice but to go out and explore this anomaly with our left, right, and center eyes!” A short time later the landing party stood in a large open square. Their initial exploration had left them with the impression that the village had recently been abandoned. They had also discovered that right beneath their tentacles was a huge industrial complex that was capable of manufacturing a staggering amount and variety of items. It too had been recently left abandoned. Captain G’K'Right looked around the square. In the center a tall pole stood, stretch right up to the bottom of the clouds, wrapped in red and green stripes arranged in a right-handed spiral. To the left of the pole, someone had left a pile of boxes wrapped in colorful paper. On the right of the pole was a giant green plant of some type that formed a cone shape and it had green and red decorations hanging from its branches. As G’K'Right stared at it he realized it leaned a little to the right, the imperfection of which seemed someone how right. “Right!” said the captain “Before we turn around and get back on our ship I want to understand why our sensors still read snow but we can see and touch a complete village and a gigantic manufacturing facility.” Leftenent N’Tuk looked up from his portable sensor array, gazed left, gazed right, then gazed left again and said “Captain, I am left with no doubt. It turns out that this whole area has a temporal damping field that obscures all non-biological sensing. It is as if the sensors see what was right here about 3000 orbits of this planet around the sun ago. But what we see and touch is what is here right now. The technology required has left me amazed. The temporal generator appears to be right there on top of that pole” The captain was about to order the disassembly of the pole when, on the horizon to the right, he saw a bright red light. “Set up a defensive perimeter, right now!” he ordered. The landing team formed an arc on the left of the square behind a low wall. As they watched, the red light got brighter and what appeared to be 9 fur covered animals pulled a large red vehicle right across the sky. Once again the captain was amazed. The train of animals pulling the vehicle landed right in front of them in the square, where they realized that the red light was actually coming from an organ on the very tip of the lead animals head. Soon, a door on the right side of the red vehicle opened and out streamed bipedal creatures dressed from head to toe in green. The creatures formed a lines that stretched from the left to the… other side of the square. When several thousand had left the vehicle, a much larger, and rounder, bipedal creature came out of the opening and strode right up to the landing party. He began to speak and the team’s universal translator translating what it heard into an earpiece they wore in their right ears: “Hoo Hoo Hoo. Welcome my friends to the North Pole! I’m sorry we left no one here to great you, but right now is the only night of the year where we are not home! Ho Ho Ho! Your timing has left us un-prepared. Ho ho ho.” Captain F’Tool G’K'Right strode forward to greet the large but friendly alien. And then he stopped. A memory had popped right into his head that left him wondering. He turned to and asked his right hand man, ” P’Turn, do you think, that this might possibly… , no it can’t be right. But the more I think the more I’m left without a doubt. Could this be S’ta C’las?” As the captain looked at his childhood nest-friend, he remembered rushing with P’Turn into the nursery room on Winter’s Night to find gifts scattered under the Winters’ Night Mushroom… and a tear of joy formed in his right eye. He turned just in time to see the bi-pedal alien morph before his eyes and become S’ta C’las. In the Zelak language he heard S’Ta C’las say “N’ka, N’ka, N’ka. Merry Winter’s Night to you! F’Tool G’K'Right, you have been a good little Zelak, N’ka, N’ka, N’ka, and I welcome you to my home, right here on earth. I of course knew you were coming so we left you and your crew something here, right beneath this tree.” As the landing party rejoiced and rushed forward to put their tentacle right around S’ta C’las the captain realized, with a mystical and magical creature like this for every planet left with a civilization on its surface, no matter where his travels left him, he know that in the end, no matter how bleak the situation, no matter how difficult the challenges, no matter how deep the sadness, everything would turn out… right.
A while back I did a webinar on POST26 in ANSYS Mechanical APDL and using it with ANSYS Mechanical. You know it was a while ago because… well… it was a webinar and I have not had time to do one of those for a long chunk of time now. Anyway, as usual the files used were placed on the blog in a posting. Last night I got an email from a student in Australia who tried to use the file and found a problem with it. Now this was cool for a couple of reasons: 1) anytime someone from the opposite side of the earth reaches out to communicate, that is just makes my day, and 2) someone not only read the posting, but they tried to use it. Sometimes the only way we know people are using the content we create is when the find a problem. I’ll take it. In figuring out what was wrong I figured it might be a good time to point out some things about the file manager in ANSYS Workbench, and how using it, you can fix the problem that this project had.
Projects – A Big Directory Tree of Folders and FilesIf you ever looked at the directory your project is stored in you will see a big old tree of folders and files. All of the info needed or created for your project are stored in this directory tree. Why? Because the briliant thing about the project page is that it is designed to take all these different programs like ANSYS Mechanical, ICEM CFD, FLUENT, CFX, etc… and allow you to interact between them in a single tool set. In that each program was written by a different group of developers, and most of them when those developers worked at different companies, each one has its own unique file structure, files that it needs, and way of organization them. By giving each tool its own directory in the project, you can have the legacy data structure you need, but still keep all your files in one place where the project page actually knows where to find the information it needs.
Looking at your FilesThis is done with the Files View in the Workbench Project page. By default it is hidden. Just go to View on the menu and click Files so it has a check next to it: We did a post in the past explaining all the things this view does for you. Read it here. Fixing a Missing File If you should get the type of error message that our Australian friend got, you can easily remedy it with the files view. If it is missing it will show up with a big red X next to it instead of its normal icon. The whole line will in fact be red. If you Right Mouse Button on it you will see a couple of options:
- Repair “filename”: This allows you to hunt and find the missing file. It should say “Identify Missing File” or some such, but repair works too. Click on that, find your missing file, and you are good.
- Remove “filename” is what you use if you don’t need the file, it is gone, and you want to get on with your life.
- Open Containing Folder is nice because it will take you to the folder that the file is supposed to be in. You might poke around in there and figure out what is going on.
[The following is an email that Manoj sent the tech support staff at PADT. I thought is was perfect for a The Focus posting, so here it is – Eric] First of all I found out a way to get Mesh Generation time (if no one knew about this). In ANSYS Mechanical go to Tools->Options->Miscellaneous and turn “Report Performance Diagnostics in Messages” to Yes. It will give you “Elapsed Time for Last Mesh Generation” in the Messages window. Next I did a benchmark on the Parallel Part by Part meshing of a Helicopter Rotor Hub with 502 bodies. The mesh settings were getting a mesh of about 560,026 elements and 1.23 million nodes. I did Parallel Part by Part Meshing on this model with 1,2,4,6 and 8 cores and here are the results. Can I say “I LIKE IT!” 1 core: 172 seconds (1.0) 2 core: 89 seconds (1.9) 4 core: 52 seconds (3.3) 6 core: 38 seconds (4.5) 8 core: 33 seconds (5.2) Of course this is a small mesh so as the number of cores goes up, the benefits go down. I will be doing some testing on some models that take a lot longer to mesh but wanted to start simple. I’ll make a video summarizing that study showing how to set up the whole process and the results.
One of the best parts of having other offices is that we get to visit during the Holiday Season and have small dinners with the employees, families. (And even a lapsed employee and spouse sneak in now and then) This year we enjoyed dinner in Old Town Albuquerque with the New Mexico Staff and their Significant Others, then headed up to Denver for dinner with the Colorado Staff and family. It kind of reminds us of what it was like in the early days of PADT when we could all sit around one table. We had a great year with good growth in both states, and hope to see more people around the tables next year!
