This Week in CFD

Business

  • If you’re interested in the state of the Russian MCAD market, a bilingual research paper is available from Ralph Grabowski, editor of upFront.eZine.
  • Two perspicuous posts from MonicaSchnitger:
    • Exa had a good Q4 rounding out a good 2014. Revenue was up 12% to $54.5 million of which $44.6 million was license revenue (up 8%). The forecast for 2015 includes double-digit license growth. Regarding the needs of their automotive customers Exa stated “regulatory changes are forcing them to get more accurate, more realistic simulation capabilities.” [Because Exa is, to my knowledge, the only publicly traded, purely CFD company, we should all be interested.]
    • Materialise, the company behind the Magics software for CAD-STL conversions and manipulations, is preparing apparently for an IPO. Their 2013 sales totaled 68.7 million euros, a 16% increase relative to the prior year. [Because 3D printing is so closely coupled to meshing, I’m interested.]
  • It was announced that NUMECA is now an official supplier to Oracle Team USA for the America’s Cup.
  • Metacomp Technologies’ CFD++ software will now be distributed in the UK by CFD Technologies. [Disclosure: CFD Technologies also distributes Pointwise.]

Meshing and Other Stuff

  • Desktop Engineering asked the question “How can novice users determine whether the mesh model is good enough?” In their article Meshed up or Messed up? you can read several opinions. [Disclosure: One of those opinions is mine.]
  • Convergent Science announced that their CONVERGE User Group Meeting 2014 will be held in Madison, WI on 23-25 September.
  • AeroDynamic Solutions published the March 2014 issue of The Flow, their newsletter for turbomachinery designers.
This tweet from #SimulationFriday made the art lover in me very happy. I cannot find the original image source. (If you're on Twitter you need to follow the #SimulationFriday hashtag.)

Applications

  • This season’s rule changes in Formula 1 have challenged car designers to do more with less. Here’s a video from Ferrari about aerodynamics and CFD.
  • The naval architects at Robert Allan Ltd. have expanded their CFD capabilities.
  • From ENGINEERING.com comes this CFD study using STAR-CCM+ of pipe erosion caused by particle impingement.
  • From CFD Apps comes this slide deck with tips on conducting an aerodynamic vehicle study.
  • The University of New South Wales uses Fluent to improve the aerodynamics of their vehicle for the World Solar Challenge.

Software

In Any Other Carafe Would Tap Water Taste the Same?

In order to encourage the consumption of tap (as opposed to bottled) water it was decided to emphasize the quality of water through the design of glass carafes. This project, named Transparente, combines fluid properties (altitude, temperature, hardness, conductivity, pH), Italian artistic flair, and plenty of geometric design using Rhino.

    how can i get u some mesh in gambit tnx

      Hello Ali and thanks for your question.

      As obvious as it sounds, you need to export the Gambit mesh in a format Pointwise can import. If the Gambit mesh is a structured quad/hex grid your best bet is PLOT3D format. If the Gambit mesh is fully unstructured tri/tet I suggest CGNS. Gambit should support both of those formats because they’re very popular and very standard.

      If neither of those suggestions work you should probably contact our technical support engineers at support@pointwise.com. Just give them your Customer ID and they’ll help you.

      Thanks again.
