This Week in CFD

And here is the first issue of This Week in CFD for the new year. Some applications of CFD (including the Image of the Week for an overset simulation), event updates, and some interesting software work at Los Alamos to enable exascale computing. The application of the week (shown here) is a injection of sauce into gelato computed using STAR-CCM+. (I mean, c’mon – it’s sweet, wonderful gelato.)



  • By acquiring Arena Solutions, PTC can deliver CAD and PLM as a service with the combination of Onshape and Arena PLM.
  • Congratulations to Prof. Spencer Sherwin for being awarded the Prandtl Medal for his research including development of Nektar, a high-order, hp-element CFD code.
  • From Mentor Graphics, to “Mentor, a Siemens Company” to Siemens EDA.

Very interesting work on computing geodesics (shortest path) curves on polyhedral (meshed) surfaces by Sharp and Crane. Image from


  • Cognite announced a collaboration with WindSim in which the latter’s CFD technology for wind farms will be integrated with the former’s data fusion tech.
  • At Los Alamos National Lab they’ve developed software called Legion to determine which tasks in other software can be performed in parallel and how they can be best performed in parallel. The goal is to automate some of the work involved in porting applications to exascale systems. [In which we read that supercomputing applications are “essentially souped-up versions of phone apps.”]
  • CoFEA is an open-source initiative for “cooperative FEA.”
  • What is George Gabriel Navier-Stokes Problem in HPC? [If you know after reading this, please share.]
  • Know more about the various aspects of aerodynamics in automotive engineering. [Not after reading this you won’t.]
Although I’ve made it clear I’m not a car guy, this Jaguar Vision Gran Turismo SV concept car does look pretty fancy. And it was designed with CFD. Image from

Facet Animals

Thanks to alert reader Antoine, we can all shop online for faceted animals, both wall mounted and floor standing, made from pre-cut and folded paper that you glue together yourself. All from Papertrophy.

How’d you like to have a T-Rex hanging on your wall? See link above. Image from

P.S. “Facet Animals” would be a great name for a rock band.
