This Week in CFD

This roundup of CFD news and notes includes a lot of events and that’s a good thing that live events are back. Our friends at Nvidia wrote an article about CFD on GPUs that includes a lot of interesting info that you should probably see. It’s a couple years old but NASA’s video about CFD and HPC also deserves your time. And for the hard-core fluid dynamicists out there, the article about using deep learning to find singularities in solutions of the Euler equations should be right up your alley. I don’t know who needs to see this but here’s aerodynamics of a beaver.

How about some video demonstrations of dynamic computational geometry? The section on Voronoi and Delaunay is particularly interesting.

The 22nd Computational Fluids Conference (CFC2023) will be in Cannes [fancy!] on 25-28 April 2023. Call for papers is open until 20 September 2022.

Just a reminder that Mixed Order Mesh Curving by my friends and colleagues Steve Karman, Kristen Karman-Shoemake, and Carolyn Woeber is Chapter 1 in the new book Mesh Generation and Adaptation: Cutting-Edge Techniques.

Quadcopter mesh from Simscale’s article about automated mesh refinement.

CFD for use of plasma torches in aluminum scrap remelting furnaces. [You gotta love a news release that reads like a legal agreement.]

CFD for sustainable yachts.

CFD for sustainable data centers.

CFD for reducing fuel consumption.

And Now a Word from Our Sponsor

Isn’t it time you got a demo or took an evaluation of Fidelity?

Back to Your Regular Programming

If you’ve lost track of all the SPH codes out there, SPHERIC has you covered.

A really interesting “technical walkthrough” of The CFD Revolution Driven by GPU Acceleration. [Accelerated by GPUs?] “Getting to higher levels of performance is the right thing to do, because it optimizes the most expensive resource: engineer and researcher time.”

Congratulations to the 2022 Amelia Earhart Fellows, women who’ll be pursuing careers in aerospace.

Screen capture of a video showing an integration of CADfix and HOOPS.

preCISE, the “open-source coupling library for partitioned multi-physics simulations, including, but not restricted to fluid-structure interaction and conjugate heat transfer simulations,” v2.4.0 is now available.

ICYMI, we no longer have to use euphemisms like “exascale” because we now have an exaflops supercomputer: Frontier.

Enjoy this video overview of HPC and CFD at NASA.

The HPCMP User Group Meeting is coming up on 13-15 Sep 2022 in Dayton.

What’s new in the latest version of zCFD? Overset meshes for one thing.

Here is a complete learning path for CFD comprised of free online resources.

CHAM in London seeks a consultancy engineer.

Enjoy Tomer Avraham’s Turbulence Modeling.

CFD for studying the growth of dendrites in 3D printing of metal.

nTopology released new latticing technology.

ERCOFTAC seeks nominations for the 2022 Da Vinci Competition for “recognition of an excellent PhD thesis in fundamental or applied fluid dynamics and outstanding scientific contributions with engineering relevance.” Due date is 15 July.

Physics-informed neural networks are being used to prove that the Euler equations do indeed produce non-physical solutions with singularities. [If they wanted CFD solutions that have blown up they just had to ask. I’ve had plenty of those.]

Visualization of turbulence inside a cylinder flow from Beauty of turbulent convection: A particle tracking endeavor by Godbersen et al.

An enjoyable history for those so inclined: Aircraft Engines: A Proud Heritage and an Exciting Future by Rolls-Royce’s Parker and Fedder.

Tecplot has an opening for a technical support specialist.

CFD for a Maserati convertible.

Get Navier-Stoked

This poster is one of the most brilliant celebrations of CFD I’ve seen on social media in a long time. It’s from Prof. Alberto Figueroa from the Computational Vascular Biomechanics Lab at the U. of Michigan. I don’t even know what’s illustrated on the poster; I just find it graphically appealing.

I don’t know about you, but I plan to steal the hashtag #NavierStoked. Brilliant.

IMPORTANT? There won’t be an edition of This Week in CFD next week (15 July) because I’ll be at the International Conference on CFD.

  1. David Garlisch says:

    The poster looks like a renumbered mesh matrix that concentrates data along the diagonal. I am not sure if the colorization means anything.

  2. Greg says:

    Image appears to be a “spy” plot of a sparse linear operator. Coloring suggests that it may be “augmented” with some constraints — perhaps implemented via Lagrange multipliers. Here’s an example of how matrices like this might be written in literature (note the dashed lines):

  3. It is the left hand side matrix of a CFD stabilized finite elements formularon. Red is derivate momentum / Derivative velocity, blue derivative momentum / derivative pressure (and transpose, derivative continuity / derivative pressure) and red is derivative continuity/derivative pressure.
