Phoenix Business Journal: ​Finding hope at a technology open house

pbj-phoenix-business-journal-logoSometimes you hold an event as a way to educate the community, and then it comes back and educates you. This posting “​Finding hope at a technology open house” shares what we learned at our SciTech Festival open house this year.

Phoenix Business Journal: ​For tech companies, ‘green’ is all about efficiency, stupid

pbj-phoenix-business-journal-logoEngineers see the serious problems of climate change, lost habitat, pollution, and sustainability differently. This article, “For tech companies, ‘green’ is all about efficiency, stupid” is about how tech companies need to ignore the rhetoric and noise and focus on using science to produce solutions.

Kids, Pizza, Engineering – A Fantastic SciTech Festival Open House at PADT

ScitechFestivalLogoWe thought we would open PADT’s doors to families and maybe a few people would stop by. Over 250 people did just that.  What a great evening of smiling kids and adults enjoying the excitement of engineering.  Exciting engineering? Yes, we know enough to not talk about quality system protocols, matrix inversions, and non-linear turbulence model convergence. We stuck to 3D Printing, elephants on skateboards, and 3D scanners. And we fed everyone pizza.

FullSizeRenderIt was a great evening where everyone learned something.  The focus was on exposing what engineers do, what PADT does, to people who may not be technical. Mostly kids but we also saw it as a way for engineers to show their family members and friends what engineering is about.  The results far exceeded our expectation, mostly because of how great everyone who showed up was.

Some of the quotes from people who have emailed to thank us are:

“Thank you for opening up your office to me.  What a cool place!  Even though I have been familiar with and worked with 3D printing for 20+ years, it is always nice to see the new technology, products, and the output of the products. “

“… to see my son and all of the other kids so excited and amazed was truly awesome. Mason told me it was the best night of his life! And this morning his first words to me where thanking me for taking him to the event and when can we go back.”

“This is such a great opportunity for me to show my grandkids what I spent my life doing, and seeing them get so excited about it is wonderful”  

The best part of the event for most of us here at PADT were the fantastic questions.  As one of our engineers said “for 2 hours I was just lost in the joy of positive human interaction.”  We do love what we do here, but it was nice to share it with other people.

Below are some pictures from the evening.  Make sure you sign up for PADT’s email list to get invites to future events.

Phoenix Business Journal: When did starting a new company become about funding?

pbj-phoenix-business-journal-logoRaising 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.

Phoenix Business Journal: When was the last time you thanked an engineer?

pbj-phoenix-business-journal-logoHave 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?

10x with ANSYS 17.0 – Get an Order of Magnitude Impact

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.

ANSYS-R17-Banner
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:

temperature-on-a-cpu-cooler-bgTighter Integration of Multiphysics

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.

simplorer-17-1500-modelica-components-smTo 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.

Improved Usability

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.

clip-regions-with-named-selections-bgThe 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.

import-ecad-layout-geometry-bgIndustry Specific Workflows

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.

ansys-fluent-hpc-max-coresOverall Capability Enhancements

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:

  1. Improvements to distributed solving in ANSYS Mechanical that show good scaling on dozens of cores
  2. Enhancements to ACT allowing for greater automation in ANSYS Mechanical
  3. ACT is now available to automate your CFD processes
  4. 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)
  5. Fracture mechanics
  6. ECAD import in electromagnetic, fluids, and mechanical products.
  7. A new solver in ANSYS Maxwell that solves more than 10x faster for transient runs
  8. ANSYS AIM just keeps getting more functions and easier to use
  9. A pile of SpaceClaim new and improved features that greatly speed up geometry repair and modification
  10. Improved rigid body dynamics in ANSYS Mechanical

ansys-17-ribbons-UIMore to Come

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.

ASME OMAE2015 Paper: The Importance of Grid Convergence Studies in the Design of a Semi-Submersible Platform

asme-papers

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 

Abstract:

omae-2015-FLUENT-off-shore-flowThe 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.

 

Webinar: PADT Answers your Questions on Metal 3D Printing

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.
