This Week in CFD

Image from FYFD, “celebrating the physics of all that flows.”

For reasons I can’t explain, I’m really excited and energetic today about CFD and work in general. Is it because of summer? Start of the Olympics? Being three months in to our new relationship with Cadence and Numeca and really starting to gain traction on cool new CFD stuff? Compiling this week’s CFD news didn’t harsh my buzz either. There are a lot of good CFD jobs open for those of you looking for something new. A couple of big events with lots of CFD and meshing are happening in the next few weeks. Plus all the other news and some fun(ny) stuff too. Shown here is a cool oil flow visualization of a wing from FYFD. If you aren’t reading FYFD, you should be.

Next week’s 16th U.S. National Conference on Computational Mechanics features two minisymposia that are near and dear to my heart. First is the Symposium on Trends in Unstructured Mesh Generation (aka MeshTrends). Second is Industrial Applications of IGA (isogeometric analysis) at which I’ll be presenting an overview of the CFD Vision 2030. There’s still time to register for this virtual event.

CFD for Aston Martin’s first SUV. [This website has enough ads and flashy things that it makes MySpace look like Google’s home page by comparison.]

Check out this case study of a slender marine vessel that’s stabilized against roll-over in high cross-winds.

This image of a particle simulation from OMNIS/Impacts is just one example of the on-demand webinars available from Cadence CFD for your summer beach viewing. [You do take your tablet to the beach for watching videos, right?]

You can still register and watch the recorded sessions, including the keynotes and CFD presentations, from CadenceLIVE Americas for free.

For those looking for new opportunities:

I’m a sucker for a grid pic. In this case, a Cartesian mesh from SOLIDWORKS Flow Simulation for use in a thermal simulation of a CPU heat sink. Image from

CFD for generating downforce on the 2022 Cadillac CT4-V Blackwing.

Coming up next month (August) online is AIAA Aviation which is always chock full of great CFD stuff. [My father only drank Chock Full o’ Nuts brand coffee so every time I use that phrase I think of him and that yellow and black can.] I’ll highlight a few events here.

  • Technical Panel: The Impact of Physical Modeling on CFD Capabilities
    • Mon 02 Aug at 1pm eastern: Panelists include Brian Smith, Florian Menter, Oriol Lehmkhul, Venkat Raman, and Meelan Choudhari. Sponsored by CFD 2030 Integration Committee.
  • Technical Paper: CFD Vision 2030 Road Map: Progress and Perspectives
    • Tue 03 Aug at 1pm eastern: This paper summarizes the CFD 2030 IC’s first formal assessment of progress toward the Vision.
  • Technical Paper: Boundary Representation Tolerance Impacts on Mesh Generation and Adaptation
    • Tue 03 Aug at 2:30p eastern: The title is pretty self-explanatory and the authors are Mike Park (NASA), Bob Haimes (MIT), Nick Wyman (Cadence), Pat Baker (Cadence), and Adrien Loiselle (INRIA).

CFD for big hole technology. That’s right. Big. Hole. Technology. For motorcycles. With a big hole.

M-Star’s GPU-based LBM CFD methods allow for simulating complex flow such as the agitated tank shown here. Image from [Agitated Tanks would be a great name for a rock band and yes I included this image primarily to use that line.]

If you’re not aware of NASA’s Advanced Modeling and Simulation (AMS) seminars and the online archive of recorded seminars, you are now.

CFD for multiphase simulation of a deaerator. [I had no idea such things existed. They removed dissolved oxygen from boiler feedwater that might otherwise corrode the boiler over time.]

The folks at CFD Support shared their list of open-source software for CAE. [Semtex had me a little worried at first.]

CFD for sail-powered cargo ships.

Interested in Electromagnetic Interference and Thermal Analysis of Electronic Systems? Have I got an e-book for you.

DNS simulation of a jet flame using 230 billion mesh points and running on over 450,000 compute cores may be the biggest simulation EVAR.

There’s still time to register for CadenceCONNECT Aerospace & Defense Systems Day on 28 July when you’ll learn about all the latest tools and techniques including CFD.

ESI OpenCFD released OpenFOAM v2106.

The OpenFOAM Foundation released OpenFOAM 9.

Retopology is a fancy word meaning coarsening a mesh. Good thing this Complete Intro Guide for Beginners was available.

Why fluid dynamics matters to football. [No, the other one: futbol.]

Sigmetrix released CETOL 6σ Version 11.0 for tolerance analysis.

CFD for the McLaren 720S GT3X, a fast car.

What does Van Gogh’s iconic Starry Night have to do with fluid dynamics and turbulence? Science tells us his depictions of light and atmosphere are remarkably close approximations to Kolmogorov’s ideas of energy in a turbulent fluid.

P.S. As you may have notice, I was having a bit of trouble with WordPress’ twitchy text selection for setting hyperlinks. They all still work, just with more or less of the relevant text than I would’ve wanted. And I was too lazy to go back and edit.

    I read your “This week in CFD” weekly. I like the combination of overview and personal view and comments.
    Question: Apart from “CFD Vision 2030” are there other people groups sharing different opinions on what CFD should look like in 2030 ? I think of large groups of CFD users in certain industrial areas like automotive. Why should just NASA tell where the vision goes ?

    • John Chawner says:

      Hello, Viehl. Thanks for reading and commenting.

      Yes, there are several efforts similar to NASA’s CFD Vision 2030 Study. There is a national effort in Japan to do something similar (not yet published). There is a turbomachinery study I’ve cited on this blog before. From a broader perspective there’s the ASSESS Initiative. I’m certain there are many others.

      NASA should not be the only organization supplying the vision for CFD. For one thing, their applications are specific to the aerospace market. However, I’m not aware of anything like this for marine or automotive applications. (My ignorance does not mean they’re not out there.) In addition, AIAA’s workshop model for assessing the advancement of CFD is being emulated in other markets such as automotive. It just takes people to step up and get involved.

      However, I personally believe what’s cited in the Vision 2030 study has pretty broad applicability.
