This Week in CFD

This week’s cornucopia of CFD news comes with several reading assignments: 80 years of the finite element method, quantum computing, curves and surfaces, computational simulation, and OpenFOAM book, and cloud PLM among others. Would love to read your thoughts on any of these in the comments. But don’t worry if you’re word-challenged. There are plenty of event news, software releases, and CFD applications that you can skim. Shown here is a beautiful image of two fluids mixing.

Presentations from the 2022 OpenVSP Workshop are now available online. What’s OpenVSP? It is a “parametric aircraft geometry tool.”

Speaking of OpenVSP, version 3.29.0 was released.

For you fans of turbomachinery CFD, Cadence is co-sponsoring next-month’s GPPS 2nd Turbomachinery CFD Workshop which will be held in a hybrid format. The workshop will focus on RANS simulations of the TUDA-GLR-OpenStage transonic axial compressor and the BUAA low speed large scale axial compressor-Stage B. Hope you can join us.

The 2022 Overset Grid Symposium will be held on 01-03 November in Suffolk, Virginia (near NASA Langley). Abstracts are being accepted through the month of August and registrations are due by the end of September.

ICYMI, Cadence acquired Future Facilities, a “provider of electronics cooling analysis and energy performance optimization solutions for data center design and operations using physics-based 3D digital twins.” In other words, CFD and thermal simulation for everything from PCBs to complete data centers.

Why have I included this image? Let me count the ways. 1. I like (American) football and look forward to the season starting in a matter of weeks. 2. I like CFD. 4. It was the first decent CFD image I’d found so far for this week’s news. 4. The article about accelerating CFD computations on AMD chips was written by Josh, the new guy on the product management team at Cadence Fidelity CFD. Image from

Here’s something to add to your bookshelf: Eighty Years of the Finite Element Method: Birth, Evolution, and Future by Liu, Li, and Park. Openly available via SpringerLink.

What do you think of this quote from Edward Teller? “A state-of-the-art calculation requires 100 hours of CPU time on the state-of-the-art computer, independent of the decade.”

Speaking of computing and by extension programming, I learned to program in C by reading Kernighan and Ritchie’s The C Programming Language, truly one of the classic texts in programming. But did you know that Ritchie’s PhD dissertation was “lost” for over 50 years?

Quantum Computing: Uses, Challenges and India’s Initiatives – Explained, pointwise” from Forum IAS. [Guess how this ended up in my inbox.]

Parasolid v34.1 was released.

Ricardo sold their software business (automotive simulation) to a division of Constellation, the same folks who own Tecplot.

gStar4D computes the 3D Delaunay triangulation on the GPU.”

If you love working with curve and surface geometry [Who doesn’t? AMIRITE?], Bartosz Ciechanowski’s webpage Curves and Surfaces will give you hours of interactive edutainment. [I am not responsible for any decrease in your work productivity.]

FlowThermoLab has an opening for a CFD engineer (developer).

ICYMI, you can now watch the recordings of presentations from CadenceLIVE Silicon Valley. We also have CadenceLIVE 2022 events coming up in China, Taiwan, Boston, India, and Europe.

Registration is now open for SC22 (aka Supercomputing) in Dallas.

Rescale published their 2022 State of Computational Engineering report. (Registration required.)

TransMagic released updated CATIA 2022 and Creo 9.0 support.

Dassault Systemes had a good Q2 with software revenue up 11%.

Did you know that Cadence’s simulation software is ready for you in the cloud? Try out OnCloud platform today for your CFD.

Open CASCADE Technology 7.6.3 was released.

Tech-Clarity released the results of their State of Cloud PLM survey. (Registration required.)

CFD shows that a ship hull with a bulbous bow is much more efficient than an unappended hull.

The full text of Holzmann’s book Mathematics, Numerics, Derivations, and OpenFOAM is available online.

Why am I reluctant to include this image? 1. I’m so tired of Elon’s Musk’s “cyber bro” act. 2. I think this thing is ugly as sin. 3. I’m not a car guy. 4. CFD simulations of an approximate geometry model for the Cyber Truck indicate it’s not as draggy as many might think: Cd of 0.39 versus around 0.60 for a typical pickup.

Brice Marden’s painting covers a broad range of visual imagery from virtually monochrome canvases to swirling ribbons of color. The work shown below is the first of his I can recall seeing that has this line-based geometric motif. I have expressed on several occasions how black and white line art, whether fine art or animation art, is quite appealing to me and this definitely ticks those boxes. He’s created a very active landscape in depth that is both visually chaotic and balanced.

You can see more of Marden’s work at the MoMA’s website from a 2007 retrospective.

Bonus: NASA has had over 350 artists portray the space program in their work.
