This Week in CFD

Completely fungible and non-tokenized, today’s CFD news begins with a hopeful glimpse at a potential in-person CFD event. You should check-out the list of tips for simulation projects and let us know what was missed. And the coolest news this week IMO is work on smoothly blending two different meshes even if they have different point counts. Plus all the other jobs, workshops, seminars, fluids, meshing, cloud computing news that you might find interesting. The image shown here is a turbomachinery simulation from STAR-CCM+.

This event news might get a little complicated so hang on.

  • AIAA Aviation, usually held in June, has been postponed to 2-6 August and will be 100% online.
  • The 4th AIAA CFD High Lift Prediction Workshop, originally scheduled to be held in conjunction with Aviation, has been rescheduled to AIAA Scitech in the hopes that the workshop can be held in-person. Exact dates TBD.
  • The 3rd AIAA Geometry and Mesh Generation Workshop, also originally scheduled to be held in conjunction with Aviation and held collaboratively with High Lift, has also been rescheduled to AIAA Scitech for the same reason. (GMGW’s website has not yet been updated with the date change.)
  • A Workshop Progress Meeting for the two workshops and the participants in their Technical Focus Groups will be held online on 15 July.
  • Let’s hope SciTech and these workshops do indeed happen in-person. I plan to be there.

Complex fluid dynamics may explain hydroplaning. [Well, if it was simple we’d probably have the explanation by now. Are there any simple fluid dynamics? If fluid dynamics might not explain it, where might the explanation lie?]

COMSOL is hosting a series of online COMSOL Days for you to learn more about their multiphysics simulation capabilities. Shown here is a biomedical example [although I have no idea what it is.] Image from

Beginning next Wednesday, a PyFR seminar series aims to “help bridge the gap between academic research activities and real-world industrial requirements.”

Siemens Digital Industries Software announced that Simcenter STAR-CCM+ has achieved AWS HPC Competency status.

CFD was used to design a more aerodynamic hand cycle for para-olympians.

I just needed some eye candy here. This image is for the “10 tips” article below. Image from

From 10 Tips to Make Great Design and Simulation Projects comes “#4 Be prepared for the worst.”

Just a reminder that there’s a website for this August’s 2nd Automotive CFD Prediction Workshop (AutoCFD2).

You’re probably tired of hearing about it by now, but we wrote a 20 page paper on Preparation of Geometry Models for Mesh Generation and CFD that provides a broad overview of the topic. It’s free but we do ask you to register with a wee bit of information.

Interested in CAD software on ChromeOS? This might be the year.

This Simulia simulation of dirt deposition on a car is fascinating. They are interested in understanding the effect of soiling on the sensors all around the car. Image from

There’s a native interface to AzoreCFD built-in to Pointwise.

And here’s a brief guide to Linux for OpenFOAM users.

Our friends at Ansys were named to Fast Company’s 2021 list of the most innovative companies for their development of Ansys Discovery.

Not CFD but it’s pretty cool that Microsoft just ran a 2-year test of a data center in a sealed, underwater pod.

We would love to fill some open positions on our Engineering Services (i.e. applied meshing) and Product Development (i.e. programming) teams with people who share our core values of commitment to excellence, attention to detail, taking initiative, collaboration, and fun.

If you’ve ever wanted to smoothly blend between two different meshes (with different point counts), here’s how. [Be certain to watch the video at the end of the page.]

From the great scientific journal USA Today comes Outdoor Seating Isn’t Always Safer than Indoor Dining. [Interesting that they are comparing the relative safety of seating versus dining but whatevs. Also, outdoor dining from what I’ve seen is just sitting inside a closed space that’s not inside which is just inside dining with extra steps.]

Altair offers the white paper Ultra-Fast High-Fidelity CFD on GPUs for Automotive Aerodynamics based on their ultraFluidX code. (Registration required.)

Aerodynamics of Cycling Skin Suits Focused on the Surface Shape of the Arms.[Link is to a PDF of the article via a Twitter-shortened URL.]

“Meshing is really hard because it’s intrinsically tied to CAD, and CAD has limited tolerance. That, in turn, limits the design engineer’s ability to mesh a large geometric scale.” Thus begins an article about ANSYS’s approach to meshing complex EM systems with a multi-scale approach.

Compass is running a survey on the use of CAE/FEA software.

Siemens has an opening for a Cloud Development Intern for this summer in Huntsville.

CFD for more accurate flow meters.

Lifecycle Insights wants to hire an Industry Analyst.

And now for something completely different. Instead of a geometric or mesh-based artwork we have today one of Monet’s many paintings in his series on Waterloo Bridge. I had not seen any of this series until yesterday and I’m stunned by its effect. The sense of mood is palpable, its minimalism is offset by the details revealed by the brushwork. And the colors – wow.
