This Week in CFD

15_venturadiaz_p_sc18_top_v0_copy_croppedIn this first edition of This Week in CFD for the new year we find several job openings including some at Pointwise, both permanent positions and internships. There are also long reads about designers’ use of simulation and the criticality of meshing to CFD. Plus you’ll see an article about a NASA simulation of the side-by-side rotorcraft shown here in this beautiful flowfield visualization.

Open Positions at Pointwise

More Jobs

Applications

  • From HPCwire comes an article about the use of neural networks to accelerate CFD solutions without sacrificing accuracy: Deep Learning for Fluid Flow Predictions in the Cloud.
  • For my automobile loving friends I share this article/video about the design and use of CFD for the Rimac C_Two. [I found this statement about CFD to be amusing: “The air around the vehicle splits into more than 70 million parts, each of which factor into how the vehicle is affected and reacts. This is where computational fluid dynamics (CFD) simulations help to solve complex equations that are far too complicated for simpleton bloggers to comprehend.” As a simpleton blogger myself, I applaud this self-awareness.]
  • FLOW-3D publishes some cool applications such as this trench type sump pump.
  • Here’s CFD for kilns.
  • For the 2021 season, Formula 1 teams are no longer limited on how much CFD simulation they can use.
  • New [to me] is South African and USA based CFD consultancy Aerotherm.
  • From PTC comes Why Design Engineers Need to Perform Their Own Simulations. While the article identifies Creo Simulation Live as a tool that can potentially make this happen (understandable), what’s also important (perhaps more so) is understanding what design engineers want and need from their simulation tools.

News and Events

pocket-2030

A short blog post from Seth Godin reminded me of my favorite CFD report, the CFD Vision 2030 Study. He wrote “Twelve years from now, your future self is going to thank you for something you did today.” Read more from A Note from 2030. Pocket sized edition of The Study shown above with coin for scale.

Meshing and Visualization

Not Automated Meshing

Comments on a recently published article about “black box” meshing [that I haven’t finished reading] asked whether anyone still hand crafts meshes anymore. I think we can agree that artist Matt Shlian takes hand crafting to the ultimate level in his drawing Drift shown below.

Matt’s main area of expression is paper sculpture and implies that he has an engineering background upon which his artistic practice is built. “Researchers see paper engineering as a metaphor for scientific principles; I see their inquiry as a basis for artistic inspiration.”
