This Week in CFD

aneurysm1Everyone in CFD is hiring, or so it seems. Four companies, including Pointwise, are advertising for open positions and there certainly are others. Did CFD visualization need rethinking? Ceetron thinks so. And high-order, curve mesh generation is now available in the latest release of Pointwise.

News

  • SPHeric, the Smoothed Particle Hydrodynamics Research and Engineering International Community, did some rebranding resulting in a new acronym and logo.
  • DEVELOP3D shares an article about how 3-D scanning was used by The Blades, the UK’s team in the Red Bull Air Race, to capture the geometry of the aircraft as a starting point for aerodynamic modifications. [I’ve made no secret of my growing interest in the Red Bull Air Race and the fact that this season’s finale will be in Fort Worth on 17-18 November.]

Jobs, Jobs, Jobs

Software

  • Pointwise V18.2 was released with high-order (up to degree 4), curved mesh generation. [More on this in another post. The high-order mesh at the top of this post is visualized in ParaView.]
  • SU2 v6.1.0 is now available.
  • Ceetron Analyzer is a new cross-solver, cross-discipline, cross-platform post-processor for CFD and FEA.  They’re calling it a “rethink” of CAE post-processing.
  • ANSYS 19.2 was released with advances in computerized [sic] fluid dynamics with improved workflow for their patent-pending mosaic meshing technology.
  • Engineering.com writes about what’s new in SolidWorks 2019.
  • Tau Flow is a CFD consultancy based in Brazil.
  • CoolSim for AutoCAD 2.0 was released.
curvahedra-assembled

Proof that I do put my money where my mouth is. Here’s my Curvahedra puzzle, fully assembled. (I mentioned Curvahedra in a recent blog post.) For the record, it took me 3 attempts and I had to get help from Stephanie to finish it.

Events

  • The 27th International Meshing Roundtable is coming up the week after next (1-5 October in Albuquerque) and the event’s agenda is now online. [Yes, you read it correctly. I’m giving an invited talk on Tuesday morning, providing you the opportunity to sleep in until the real speakers begin at 10:00. Did you know there are precisely two reasons why meshing is difficult? That’s my topic.]
  • The Pointwise User Group Meeting 2018 (14-15 November in Fort Worth) is open for registration. Come join us for two days of meshing goodness.
  • You have one week left to enter The Meshy Award contest. The winner will be recognized at the Pointwise User Group Meeting 2018.

Here’s a teaser for Pointwise’s entry for the IMR’s meshing and poster contests. You’ll see the real thing in Albuquerque in a couple of weeks. We have way too much fun making these meshes.

Structured Grid Bench-Mark

Designer Matthias Pliessnig learned how to curve wood by making boats. The same techniques have been extended to the design of gorgeous furniture including the bench shown below.

First seen by me on Colossal, the structured quad grid caught my eye, the curving reminded me of our new high-order mesh curving capability, but it was the gorgeous use of wood that motivated me to go to his website and request a catalog.

Matthias learned some of his craft while at the University of Wisconsin – Madison. Now if I only knew a software company or two from that area who could use some cool office seating.

Bonus: When you break a fistful of uncooked spaghetti it never breaks cleanly in half – you get a spray of pasta shards. What’s the trick to getting it to break cleanly? Simulation illustrates the desired result.

    “SU2 v1.6.0” should be “SU2 v6.1.0”.
