This Week in CFD

FLOW-3D-Pouring-a-BeerLots of applied CFD in this week’s roundup of news and notes. And because it’s Friday, the app featured here is a screen shot from a video of pouring a beer (simulated using FLOW-3D). There’s a long-ish article on turbulence modeling that you might want to check out. And on the geometry modeling front, check out the nTopology article about filleting and the article about CAD on the iPad (iCad?).

Modeling

  • “All models are wrong but many are useful,” or so goes the saying. There are turbulence models and even geometry models, both being approximations to reality. For an in-depth look at the former, read Tomer Avraham’s post, Some Fundamental Thoughts About Turbulence Modeling.
  • Congrats to our friends at ANSYS for being named to Fast Company’s list of the 50 best workplaces for innovation. (In which their work on Discover Live is said to deliver “the first engineering software that provides real-time physics simulation and geometry editing.”)

Robust, automated filleting from nTopology. [If you like geometry as much as I do, this animation and the others at the website are pretty cool.]

This CFD simulation of a wind tunnel is from your introduction to Valerio Novaresio from Allovis Engineering, Pointwise’s new distributor for Italy.

  • Our friends at Applied CCM illustrate in 2-D how to use clustering sources for mesh refinement.
  • At the International Meshing Roundtable on Tue 15 Oct, I will be presenting work our Applied Research team has been doing on providing robust geometry access to CFD solvers (and any downstream consumer of meshes): Computational Geometry and Mesh Associativity for CFD Software: MeshLink.
  • We congratulate our own Carolyn Woeber, Manager of Engineering Services, for being named to AIAA’s Associate Fellow Class of 2020. Associate Fellow status recognizes those “who have accomplished or been in charge of important engineering or scientific work, or who have done original work of outstanding merit, or who have otherwise made outstanding contributions to the arts, sciences, or technology of aeronautics or astronautics.”

Hall of Fame Mesh

Despite being a native Clevelander, I’ve only visited the Rock and Roll Hall of Fame (designed by I.M. Pei) once and that was decades ago. I have no recollection of its faceted, mesh-like external appearance.

Noted: Alert reader Nick wonders why we didn’t grab the domain name griddy.com, now used by a a wholesale electrical provider.
