Raising money is critical, but at some point it became what startups were about. In “When did starting a new company become about funding?” I take a look at this phenomenon and offer some reasons why we should focus more on the product or service.
Have you ever thanked an engineer? In this week’s TechFlash post I explore how we live in a world that has been transformed for the better (mostly) by engineers. We are simple creatures who avoid the spotlight… but a thanks you would be nice. When was the last time you thanked an engineer?
Metal Additive Manufacturing, or Metal 3D Printing, is a topic that generates a lot of interest, and even more questions. So we held a webinar on February 9th, 2016 to try and answer the most common questions we encounter. It was a huge success with over 150 people logging in to watch live. But many of you could not make it so we have put the slides and a recording of the webinar out there. Just go to this link to access the information.
The presentation answered the fllowing common questions:
- Who are PADT and Concept Laser?
- How does laser-based metal 3D printing work?
- Are there other ways to 3D print in metal and how do they compare?
- What are the different process steps involved?
- How “good” are 3D printed metal parts?
- What materials and machines do you offer?
- Who uses this technology today?
- What is the value proposition of metal 3D printing for me?
- What can I do after this webinar?
As always, our technical team is available to answer any additional questions you may have. Just shoot an email to email@example.com or give us a call at 480.813.4884.

In all the hoopla around 3D Printing the real reason why it is important often gets lost. Check out this article to learn “The real reason 3D printing is important” to wrap your head around the long term impact of this key technology. PB
After some end of year reflection we hit upon a key factor that constantly let us close business deals faster. We share the key driver in the PBJ’s Phoenix Business Blog with the to-the-point title of “How to close business deals faster“
The ANSYS 17.0 release improves the impact of driving design with simulation by a factor of 10. This 10x jump is across physics and delivers real step-change enhancements in how simulation is done or the improvements that can be realized in products.
Unless you were disconnected from the simulation world last week you should be aware of the fact that ANSYS, Inc released their latest version of the entire product suite. We wanted to let the initial announcement get out there and spread the word, then come back and talk a little about the details. This blog post is the start of a what should be a long line of discussions on how you can realize 10x impact from your investment in ANSYS tools.
As you may have noticed, the theme for this release is 10x. A 10x improvement in speed, efficiency, capability, and impact. Watch this short video to get an idea of what we are talking about.
Where is the Meat?
We are already seeing this type of improvement here at PADT and with our customers. There is some great stuff in this release that delivers some real game-changing efficiency and/or capability. That is fine and dandy, but how is this 10x achieved. There are a lot of little changes and enhancements, but they can mostly be summed up with the following four things:
Having the best in breed simulation tools is worth a lot, and the ANSYS suite leads in almost every physics. But real power comes when these products can easily work together. At ANSYS 17.0 almost all of the various tools that ANSYS, Inc. has written or acquired can be used together. Multiphysics simulation allows you to remove assumption and approximations and get a more accurate simulation of your products.
And Multiphysics is about more than doing bi-directional simulation, which ANSYS is very good at. It is about being able to transfer loads, properties, and even geometry between different software tools. It is about being able to look at your full design space across multiple physics and getting more accurate answers in less time. You can take heat loads generated in ANSYS HFSS and use them in ANSYS Mechanical or ANSYS FLUENT. You can take the temperatures from ANSYS FLUENT and use them with ANSYS SiWave. And you can run a full bidirectional fluid-solid model with all the bells and whistles and without the hassles of hooking together other packages.
To top it all off, the system level modeler ANSYS Simplorer has been improved and integrated further, allowing for true system level Multiphysics virtual prototyping of your entire system. One of the changes we are most excited about is full support for Modelica models – allowing you to stay in Simplorer to model your entire system.
Speed is always good, and we have come to expect 10%-30% increases in productivity at almost every release. A new feature here, a new module there. This time the developers went a lot further and across the product lines.
The closer integration of ANSYS SpaceClaim really delivers on a 10x or better speedup for geometry creation and cleanup when compared to other methods. We love SpaceClaim here at PADT and have been using it for some time. Version 17 is not only integrated tighter, it also introduces scripting that allows users to take processes they have automated in older and clunker interfaces into this new more powerful tool.
One of our other favorites is the new interface in ANSYS Fluent, just making things faster and easier. More capability in the ANSYS Customization Toolkit (ACT) also allows users to get 10x or better improvements in productivity. And for those who work with electronics, a host of ECAD geometry import tools are making that whole process an order of magnitude faster.
Many of the past releases have been focused on establishing underlying technology, integration, and adding features. This has all paid off and at 17.0 we are starting to see some industry specific workflows that get models done faster and produce more accurate results.
The workflow for semiconductor packaging, the Chip Package System or CPS, is the best example of this. Here is a video showing how power integrity, signal integrity, thermal modeling, and integration across tools:
A similar effort was released in Turbomachinary with improvements to advanced blade row simulation, meshing, and HPC performance.
A large portion of the improvements at 17.0 are made up of relatively small enhancements that add up to so big benefits. The largest development team in simulation has not been sitting around for a year, they have been hard at work adding and improving functionality. We will cover a lot of these in coming posts, but some of our favorites are:
- Improvements to distributed solving in ANSYS Mechanical that show good scaling on dozens of cores
- Enhancements to ACT allowing for greater automation in ANSYS Mechanical
- ACT is now available to automate your CFD processes
- Significant improvements in meshing robustness, accuracy and speed (If you are using that other CFD package because of meshing, its time to look at ANSYS Fluent again)
- Fracture mechanics
- ECAD import in electromagnetic, fluids, and mechanical products.
- A new solver in ANSYS Maxwell that solves more than 10x faster for transient runs
- ANSYS AIM just keeps getting more functions and easier to use
- A pile of SpaceClaim new and improved features that greatly speed up geometry repair and modification
- Improved rigid body dynamics in ANSYS Mechanical
And a ton more. It may take us all of the time we have before ANSYS 18.0 comes out before we have a chance to go over in The Focus all of the great new stuff. But we will be giving a try in the coming weeks and months. ANSYS, Inc. will be hosting some great webinars as well.

Vibration induced by vortices in off shore oil rigs are a significant area of concern, and understanding them is a major area of research. In this paper, PADT’s Clinton Smith, PhD, and Tyler Smith are joined by Lubeena Rahumathulla from ANSYS, Inc. to describe how they used ANSYS FLUENT to model this situation. Get the paper here: proceedings.asmedigitalcollection.asme.org/proceeding.aspx?articleid=2465497
The design of semi-submersible platforms for offshore oil and gas operations requires an iterative process between early-stage design, numerical simulation, measurements, and full-scale design. Early stage designs are evaluated using numerical simulations, which are typically validated using measurements of a scaled model tested in a wave tank. Full-scale semi-submersibles present a unique challenge, because of the sheer size of the structure. Since VIV measurements of full scale structures are not possible, numerical simulation plays an important role for evaluating vortex-induced vibration (VIV) effects in the appropriate physical regime. The quantification of error in numerical simulation results is limited to verification-type studies, in which the error is reduced by converging the solution on the computational grid. The importance of grid convergence studies in this field cannot be understated, since it is the only way to judge solution accuracy in the absence of measurement data at the full scale. In this paper, a method for a grid convergence study of vortex-induced vibration (VIV) of a model scale semi-submersible platform is presented, in which solutions are obtained using the ANSYS Fluent CFD solver. Five levels of grid refinement are used, with the finest mesh acting as the reference solution for the coarser four levels. Qualitative results of vorticity, pressure and Q-criterion (vortex identification) are presented. Quantitative results such as the nominal amplitude (A/D) of the sway motion are used for judging the convergence of the solution as the grid is refined.
Direct Laser Melting systems have made fantastic improvements in the last five years or so, making 3D Printing of metal parts a reality. The accuracy and strength of the finished parts rivals cast parts in the same material, but with the advantages of Freeform Fabrication. In fact, everywhere we go, people have questions about Metal 3D Printing.
So we decided to hold a webinar to answer those questions all at once. Our manufacturing team, lead by Dhruv Bhate, PhD, will share with you what we have learned while working to develop our own metal 3D Printing capability and while consulting with many of our customers as they acquired their own systems.
If you would like to attend, or would like to receive a link to a recording of the event, please register here.
We look forward to sharing this exciting information with all of you.
There are so many aspects to numerical simulation worth talking about these days, and a lot of resources to get that information. Applications, theory, how-to, and where it fits into the business of making stuff. Here on The Focus we tend to concentrate on practical hot-to things, and the ANSYS Advantage magazine has focused on the application stories along with some how-to. What has been missing a a resource for how simulation impacts business, and how users of simulation are making other improvements in their business.
Enter “Dimensions.” This new e-publication is from the same team that does the ANSYS Blog and ANSYS Advantage, but it has a decided business slant – WAIT!!!. I know, your an engineer, the world “business” scares you. Don’t worry, this is value added info, not a bunch of fluff.
Take a look at the first issue here. I’ll be honest, I kind of opened up expecting to page through going “whatever,” “right, no one does that,” and “who cares.” But I found myself skimming all of the articles with interest, and reading a couple completely. There is some good stuff in here. LIke an interview with Airbus engineers on about the challenge they face in designing their products. Or who Whirlpool uses social networking to facilitate communication between their users around the world. There is some simulation stuff in there, like how Siemens Power leverages simulation to make better power generation products. And a lot more.
Take a look, it won’t hurt, I promise. If you want something more technical, forward the link to your boss at least.
Colorado is a major contributor to the space industry, and they are quickly adopting 3D Printing to keep costs down and get to space faster. In this article, “Colorado Companies Bringing Space Costs Down to Earth” the DBJ explores how automation and 3D Printing can have a big impact on cost and schedule. Many of the companies sighted in the article are PADT customers, and PADT’s very own Norman Stucker was quoted extensively for the article.
