This Week in CFD

Applications

  • What is an unexpected place to find scientific visualization? Here’s EnSight in Jeopardy’s Daily Double. [Go to 1:39]
  • Here’s a video demonstration of applying Midas NFX CFD to an external flow problem. [1-hour recorded webinar. Includes intro to their product line.]
  • For those interested in efficient evaluation of B-Spline surfaces, Intel documents their work with OpenCASCADE here.
  • Here are some time-saving tips for STAR-CCM+ v9.04.
  • In the same vein, here’s a tip for SolidWorks Flow Simulation.

Not CFD

Because my first “real” job was doing computational work related to wind tunnel testing (running a method of characteristics code for models to be put in NASA Glenn’s 10×10 supersonic tunnel) I still have fondness for these test facilities. The photo below, taken from FYFD, captures the scale of some of the test infrastructure we’ve lost; specifically, AEDC’s supersonic tunnel.

The scale of AEDC's supersonic wind tunnel is impressive as evidenced by this vintage photo. Image from FYFD.

Software & Business

  • SCIRun, an environment for modeling and simulation, now includes biomedical components.
  • Exa had a good first quarter with revenue of $13.8 million (85% licensing, 15% projects) for a 10% increase year-over-year. [Reminder: I’m interested in Exa’s business performance because they are the only all-CFD, publicly traded company that I’m aware of.]
  • Siemens PLM Software has released NX 9.0.2.
  • This is interesting. Graebert announced that they’re working on a DWG CAD editor (not just a viewer) for Android tablets. Actually, the really interesting part is buried in the promise of a “new tablet-specific user interface.”
  • Materialise’s 3-matic has joined Altair’s Partner Alliance.
  • The CAD Insider writes briefly about CONVERGE CFD.
  • The Texas Advanced Computing Center‘s 13th anniversary is celebrated in this infographic.

The Strong and the Lonely

Jonty Hurwitz works at the intersection of science and art. I believe from the title of his painting The Strong and the Lonely that he really understands mesh generation.

He shared with me a few thoughts on the difference between meshes for art and meshes for science and I’ve paraphrased them below.

  1. A mesh for art needs to touch on a deeper meaning than just the mesh itself. It is the responsibility of the artist to attribute this meaning and convey it.  In a way, the engineering “market” is easy, it’s about making something that resonates with a wider group.
  2. A mesh for art needs to evoke some kind of emotional reaction (other than boredom). [My god, he really does get meshing.]
  3. A mesh for art needs to challenge the norm in some way, push the boundaries beyond the way engineers see it.
