This Week in CFD

If I was to describe this week’s edition of This Week in CFD the words would be “off topic.” For whatever reason, the articles and activities are all over the place with respect to fluids and computing and beyond. I would be remiss if I didn’t note that we’ll begin with three upcoming events from Cadence CFD. After that there’s machine learning and AI, quantum computing and quantum fluids, GPUs, software releases, and a paper on how to write a technical paper that I’ll certainly be reading.

There’s still time to register for the live online training course New Features in Pointwise V18.5 on 25 January. All current customers will benefit from quickly coming up to speed on the latest capabilities.

CFDers in the automotive world should be interested in the CadenceTECHTALK (aka webinar) Accelerate Innovation with the Omnis Automotive Wizard for CFD Simulations on 10 February.

And CFDers in the aerospace world will enjoy the webinar Rapid Design Analysis Pairing Pointwise Meshing and FlightStream on 15 February.

Thanks to the alert reader who pointed me at this article on about a technique called digital circilism by artist Ben Heine. What I’m most intrigued by in the article Celebrity Portraits Made From Thousands of Circles is the inclusion of Jesus whom I didn’t know was considered a celebrity.

How big of a dataset does AI need to learn from? Turns out, smaller than you think.

Here’s where you can get your bloody models: the vascular model repository is an open-source database of normal and diseased human cardiovascular geometry models.

Keenan Crane of geometry fame has his own 3D Model Repository. For example, the image below is his Ogre model (imported as OBJ) in Pointwise just waiting to be meshed. [Not nearly as sinister in pink on blue.]

I honestly don’t recall why I bookmarked the PDF of NASA SP-8100 from 1974: Liquid Rocket Engine Turbopump Gears. Maybe one of you will enjoy it. asks “When disruption comes to simulation, will GPUs take victory?

Metaphysics turns out to be correct. There are an infinite number of universes. “NVIDIA Omniverse is an easily extensible, open platform built for virtual collaboration and real-time physically accurate simulation.”

This has nothing to do with CFD but a lot to do with the quality of freeform surfaces and my Disney fandom. “The term “mouse ears” is used to describe perceived imperfections in car bodies.”

“Future Facilities has today launched Release 16 of its industry-leading Computational Fluid Dynamics (CFD) software and digital twin technology, 6SigmaDCX.” [There I go again. Just copying and pasting quotes, this time from Beware: I had to complete a captcha just to see this webpage. Seems a bit extreme.]

Last year I found an article about how to read a technical paper. Here’s its counterpart. Writing a Scientific Article: A Step-by-Step Guide for Beginners.

The OpenFOAM Foundation’s funding campaign is halfway to its 2022 goal in case you’re interested in paying for a maintenance plan.

CFD for cardiovascular flow modeling using machine learning via an NSF CAREER grant.

CFD for the 2022 Formula 1 car.

BosonQ Psi launched Q-SaaS, quantum computing as a service for CAE simulations.

BosonQ Psi also asked whether quantum fluids can explain turbulence in classical fluids. [Warning: light gray text on white background.]

Syracuse University graduate student Libin Yang won second prize in the Science as Art competition for this photograph from a scanning electron microscope of fungus growing on wood. [Full disclosure: I am a Syracuse alum, class of ’84.]

AMD’s new EPYC chips are behind Amazon’s EC2 Hpc6a Instance Optimised High-Performance Computing (HPC) product.” [I did it again. So lazy.]

What’s new in Simcenter 3D 2022.1.

I resisted the urge to amplify the alliteration in this article about NASA’s use of pressure sensitive paint for wind tunnel testing of aircraft.

Beta CAE released v22.1.0 of their software suite.

After having spent some time rereading and thinking about survey results that indicate simulation and AI are the two most impactful technologies for the design process in the coming years (see Monica Schnitger’s commentary here) I’ve reached the (factually unfounded) conclusion that simulation is a smart-money bet and AI is a hope.

Have you been following the CFD flow solver Wildkatze? It seems to have some impressive capabilities.

This presumed CFD image of a car driving through foaming laundry detergent is apparently what gets car fanbois excited because it’s a tease of Fisker’s new electric supercar. I thought Fiskers made scissors, or “shears” as a cutting implement fanboi would say. Image from

Here’s a supercut of visualization: the list of 2021 visualization lists.

Thanks to alert reader Eric we have IKEA’s Flamtrad [pardon the missing umlauts] – meshed and 3D printed (selective laser sintering) objects de home décor. I’ll give them an ‘A’ for meshing but a ‘C’ for creepy.

IKEA’s Flamtrad as seen on Gizmodo. Unfortunately, I can’t find these items on IKEA’s U.S. website.

Bonus: Not responsible for time lost playing with this online Navier-Stokes simulator.
