This Week in CFD

There’s something for everyone in today’s muster of CFD news. There’s a CFD contest for grad students, vibrating cars, updates from the SIAM International Meshing Roundtable, a report on progress toward the CFD Vision 2030 during 2021, and plenty of events including two turbomachinery webinars from us at Cadence. Pop quiz: What is the CFD simulation shown here? a) grilling a hamburger, 2) a dangerous chemistry experiment, III) me opening the door to the weekend, or D) other? Read on for the answer.

Convergent Science announced the 2023 CONVERGE Academic Competition for graduate students to demonstrate their skills with a novel simulation in CONVERGE CFD. Applications are now open but will close on 15 December.

Electric vehicles are cool and all that, but they also present a slew of power generation, charging, and thermal challenges. Read more in Semiconductor Engineering.

ENGYS released HELYX v3.5.1, their open-source CFD package.

[Didn’t we agree last week to cease and desist with “boffins”?] Vibrating cars. Yes, that’s right. Can you reduce a car’s drag by vibrating its exterior surfaces?

Ansys acquired C&R Technologies thereby bringing Thermal Desktop into their portfolio.

Siemens launched Solid Edge 2023 with a Saas option, an updated UI, meshing enhancements, and more.

PTC launched Onshape Simulation, cloud-native simulation in Onshape.

[I don’t usually cite market research predictions because most of the ones that land in my inbox are utter crap, but…] The simulation software market is forecast to grow at a 13% CAGR from 2022-2027 starting from its $11.5B size in 2021.

Maths boffins [OMG, I’m doing it myself now] will enjoy this List of Algebraic Geometry Definitions and Theorems.

In nine days (as of the time this was written) Formula 1 will convene in Austin, Texas for the United States GP. Of course, our partners from McLaren Racing will be there proudly sporting the Cadence brand on their car. They’re working with Cadence Fidelity CFD to improve their cars’ performance. You might want to take a look too.

Did you hear? On 16 November we’re going a live webinar with the folks at on How to Efficiently Mesh Complex Turbomachinery Tip Blades with High Accuracy. Join us.

A select group of papers from the 28th International Meshing Roundtable have been published in a special issue of the journal of Computer Aided Design.

Speaking of the IMR, here’s the latest news about next year’s event.

  • The SIAM International Meshing Roundtable 2023 will be held in Amsterdam on 6-9 Mar 2023.
  • The CFP has closed but the call for research notes remains open until 06 Jan.
  • Your note of commitment for the technical poster session is due by 01 Dec.
  • Your note of commitment for the meshing contest is also due by 01 Dec.

When I posted this to LinkedIn it go a lot of reactions and shares so I’ll repeat it here. The AIAA’s CFD 2030 Integration Committee published Vision 2030 Roadmap Progress and Technology Highlights for 2021. This is a freely available online PDF so check it out.

Join us on 09 Nov for a joint webinar with our partners at Concepts NREC and hosted by ASME on End-to-end Design and Modeling of Turbo Compressors for Hydrogen Applications.

You probably don’t need to work at Lawrence Livermore National Lab to benefit from reading Picking an Open Source License at LLNL: Guidance and Recommendations from the Computing Directorate.

I’m still sorting through all this data but there’s a GitHub repository with “Generic 3D shapes for running CFD with VECTO trailers & support issues,” basically a geometry model for a tractor-trailer.

I’ve shared Jack Tworkov’s work here before. All I’ll say about the painting shown here is how much I enjoy the contrast of the structure of the quad grid and the unstructure [word?] of the triangles, the rigidity of the geometric forms contrasted with the fluidity of the brush strokes, and how the color palette (that I find to be fantastic here) reveals the third dimension (IMO, the ground is not the black parts).

See more of Tworkov’s works at the Van Doren Waxter gallery website.

Bonus: Science reveals the quickest way to grill a hamburger. [But is it the best way? LOL. Trick question. I don’t own a grill. Actually, it was a rhetorical question. Nope, I don’t even cook.]
