Let’s get Navier-Stoked because it’s Friday and time to review recent news from the world of computational fluid dynamics. I want to draw your attention to a few specific articles beginning with the importance of stupidity. In case you couldn’t join us on the island of Maui for the 11th International Conference on CFD [humble brag], the proceedings are now online and will provide a weekend’s worth of reading. Also be certain to spend time with misconceptions about FEM and Jack Dongarra’s keynote on HPC. Shown here is a computational electromagnetics simulation of a B-1 aircraft performed on a Gridgen mesh from way back in the day.
Have you heard about Cassyni? It’s a platform to “Discover, watch, run, publish and cite online research seminars.”
Want to see how to generate a mesh in Fidelity Pointwise? Here’s an introductory tutorial video (40 min.) done in Cadence OnCloud, our cloud-based SaaS platform.
Altair open-sourced Radioss, “a powerful, industry-proven finite element solver for dynamic event analysis.”
CFD for optimizing VTOL drone design using AirShaper.
ESI’s revenue for 2022 H1 was up 6% to €84 million which Monica Schnitger reports builds momentum toward the company’s OneESI 2024 plan.
CFD for increasing data center performance with Future Facilities’ software (now part of Cadence).
And CFD for data center thermal simulation by Meta, using the February 2021 severe winter storm in Texas [aka SNOVID] as a validation case.
AIAA announced their 2022 undergraduate scholarship winners.
CFD for Ferrari’s new SUV. [It features a “dry-sumped V12” which sounds like something requiring a visit to the doctor.]
Coming in 2024 in conjunction with AIAA SciTech is the WMLES Workshop on Smooth Body Separation.
The Importance of Stupidity in Scientific Research includes the statement “we don’t do a good enough job of teaching our students how to be productively stupid – that is, if we don’t feel stupid it means we’re not really trying.” [According to this, I must be trying very, very hard.]
The proceedings from the 11th International Conference on CFD are now online for you to download and enjoy. Of course, my paper on my favorite topic – the CFD 2030 Vision – is included.
FLOW-3D 2022R2 was released that includes, among other things, unification of the desktop and HPC compute engines.
CFD for a cycling helmet.
In Some Popular Misconceptions About FEM, Dr. Chennakesava Kadapa includes “higher-order elements require curved meshes” as one misconception. The subtlety involves high-aspect ratio cells near a highly curved boundary (e.g. boundary layer resolution for RANS). By increasing the degrees of freedom per cell a high-order mesh can or should use fewer cells. Making a coarse mesh on a geometry model with a lot of curvature virtually requires mesh curving in order to accurately represent the boundary shape.
As you may recall, the ASSESS Initiative is now part of NAFEMS. Which is why registration for the NAFEMS ASSESS Congress 2023 is available at nafems.com. Next year’s congress will be in Atlanta on 26-28 March. For those of you new to ASSESS, “The NAFEMS ASSESS congress brings together key leadership participants including experts, industry analysts, software providers, researchers, simulation users, and others in the community of model- based analysis, simulation and systems engineering with the goal to to guide and influence the ASSESS initiative’s efforts related to software development and deployment strategies.”
Altair released Simulation 2022.1.
CCTech released Autonomous HVAC CFD 2023.
CFD for the new Buffalo Bills football stadium.
CFD for an electric dayboat. [Which implies the existence of a nightboat.]
Fluid dynamics to the rescue: identifying deepfake audio.
Convergent Science launched Converge Horizon, a cloud platform for users of Converge CFD.
AirShaper validates the low drag claims for Rivian’s pickup truck.
When Jack Dongarra speaks about computing, it’s a good idea to listen. HPC: Where We Are Today And A Look Into The Future.
Here’s some insight into ITI’s geometry-driven meshing.
Presented without commentary [You are probably thinking “Hooray, none of his drivel.”] is a painting by Linda Besemer as originally found in an article from Cal State Long Beach about an exhibition held earlier this year. See link below.
Bonus: DreamWorks Animation open-sourced their renderer, MoonRay.
