This Week in CFD

precambrian-paleoecologyFor today’s post-Independence Day (in the U.S, although I guess it’s still post-yesterday everywhere) edition of This Week in CFD, we start with this unique application of CFD: studying the manner in which a 500 million year old organism fed (so-called gregarious suspension feeding, a term I’m still trying to parse). Fans of OSS will like the new release of OpenFOAM and the launch of the SU2 Foundation. Plus there’s the usual suspects: applications, software releases, and articles.

  • Mathematicians have proved that not all manifolds can be triangulated.
  • Hopefully you’ll find that the Niagara Falls-themed case for the International Meshing Roundtable’s meshing contest can be triangulated. Intent to participate due by 15 August.
  • Before you start making room in your datacenter for a quantum computer we need to figure out why they become unreliable before a typical computation is completed.
  • byteLAKE has created optimized CFD kernels to accelerate CFD solution time.
  • Trying to figure out exactly what IBM’s LinuxONE is and how it might be used for CFD.
  • How accurate is SolidWorks Simulation for FEA?

Transmitting Mesh

I’ve had Margaret Bourke-White’s 1935 photograph of the WOR Transmitting Tower hanging on my office wall for quite some time now. Best known as a pioneering photojournalist, she also (in my opinion) had a great eye for capturing technology from unique perspectives.

In WOR Transmitting Tower she manages to compress hundreds of feet of tower into something absolutely flat, or at least something ambiguous: are you looking up or down? Also, this open structure which is designed for transmitting/sharing radio broadcasts looks like a cage when viewed from below.

For more information, see her page at the International Center of Photography.

Bonus: Alert (and apparently hungry) reader Tim shared this article about the fluid dynamics of making crepes. “Just doing nothing does a reasonable job” which is kinda where I stand on the whole cooking thing.
