This Week in CFD

As we approach year’s end, the CFD news includes great news in the form of live events coming up next year. Plus there’s a lot of great (and rather large) visuals to share. And while I had hoped to clear my backlog of news, there’s plenty more to share next week. Shown here is a detailed view of the image of the week. No hints; you’ll have to click through to see what it is.


  • The SIAM International Meshing Roundtable (23-26 Feb 2022) will be held entirely on-line and will not have a registration fee. Here’s an announcement with all the implications for going online.
    • Cadence continues our long tradition of being a proud sponsor of the IMR.
    • A fun part of the IMR is the meshing contest and this year’s geometry model is the iconic Seattle Space Needle (see below). [You’d think we’ve had enough of needles in 2021 but whatevs.]
  • Did you hear that Philippe Spalart has joined Flexcompute as Director of Fluid Sciences?
  • The Cray User Group meeting will be held in Monterey on 2-5 May 2022. The call for papers is open and abstracts are due 23 Jan 2022.
  • The International Conference on CFD will be held in Hawaii on 11-15 July 2022. Abstracts are due 02 Feb. [This info is so fresh the website hasn’t been updated yet.]
  • The NAFEMS Americas Regional Conference 2022 will be held on 21-23 June 2022 in Indianapolis. Cadence is a proud sponsor. Your abstract is due 15 January.
The geometry model for this year’s IMR meshing contest as displayed in Pointwise. See contest details above.

Simulation of the week: Thanks go alert reader Michael for pointing me at Can the X-wing survive the reentry to Dagobah? This image is a cropped version of the poster that’s paired with the paper.



  • The Good: Bartosz Ciechanowski has created a webpage that’s both wonderfully interactive and highly informative. Enjoy Curves and Surfaces.
  • The Bad: Why CAD Surface Geometry is Inexact
  • The Ugly: Search “SHAPES WE LIVE WITH” on YouTube. I’d link to it directly but it’s a strong PG-13.

What’s the Sound of One Mesh Speaking?

Thanks to alert reader Ray, there’s still time to get this wifi speaker frame with unstructured mesh d├ęcor under the tree in time for Xmas. [I’m seriously thinking of getting this even though I don’t need it.]
