This Week in CFD

Ever wish you could slow down or stop time so you could really enjoy something? This week’s article includes several items that can serve as a time sink. The “image of the week” deserves detailed inspection. Soccer fans (aka futbol fans) will want to spend time with an article about the aerodynamic properties of this year’s World Cup ball. Several videos worth watching over and over again. And there’s an online, interactive, 2D fluids simulator that is certain to keep you engaged for hours. Shown here is something my electronics friends can appreciate: air velocity vectors colored by temperature from a simulation of cooling an electronic gizmo (details inside).

We (Cadence) have several upcoming events that are great opportunities to engage with the Fidelity CFD team.

  • The HiFiLeD Symposium, an in-person event in Brussels next week, is all about transition and turbulence. If that’s your jam, register today.
  • CadenceLIVE Silicon Valley 2023 is our big annual user conference that brings together our technical teams and our customers for two days of immersive interaction and that includes CFD. The call for presentations (due 31 January) is now open. Share your work and plan to attend to learn from others.

A couple of weeks ago, Intelligent Light participated in SC22 (aka Supercomputing) where they introduced their Kombyne product (in-situ visualization and analysis tool for HPC simulations). HPCwire shot this video on-site in case you couldn’t be there.

As you know, I don’t usually share market research here because IMO most of it is crap. However, when a study is shared by a reputable news organization that makes me feel a little better. So Technavio reports that by 2026 the CAE market will be US$5.6B which represents a 12.6% CAGR.

I don’t know who needs this but, Writing a Scientific Article: A Step-by-Step Guide for Beginners.

CFD for…

The U.S. Dept. of Energy awarded 56 grants of access to its supercomputers through its INCITE program. Cadence is happy to be on team with NVIDIA and led by U of Kansas’ ZJ Wang on the topic of “Wall-Resolved Large Eddy Simulation of the NASA CRM High-Lift Configuration.”

The ball being used in this year’s World Cup is said to be aerodynamically superior to previous balls due to its design and surface treatment (panel shapes, dimpling). [Now imagine if they changed the seams on baseballs each season.]

IMAGE OF THE WEEK: From the HPCwire article “How Supercomputing is Key to NASA Mission Success” comes this swirly depiction of vortex wakes for an advanced air mobility concept aircraft. Simulation by Patricia Ventura Diazfesta.

You have just one more week to submit your contribution for the preCICE Workshop 2023 to be held in Munich on 13-16 February.

Next year’s 18th OpenFOAM Workshop will include a validation challenge for the FDA blood pump.

When I started my work career in the way back, we were writing a lot of CFD codes from scratch. One of my colleagues felt it would be a good idea to derive the Navier-Stokes equations by hand as a necessary first step. Today, you can watch the Navier-Stokes equations be derived in a YouTube video.

Congratulations to all those elected to the class of 2023 AIAA Associate Fellows. I’d like to extend personal congratulations to Jim Coder, Adrien Loseille, Ray Maple, and John Rhoads.

ICYMI, you can watch a recording of the Fidelity Pointwise presentation at this past summer’s SU2 Conference. Cadence is a proud sponsor of the SU2 Foundation.

gpu-io is a “GPU-accelerated computing library for physics simulations and other mathematical calculations.” Shown above is an example of an interactive, incompressible flow simulation in your browser. I am not responsible for your lost time while you explore this.

ITI has integrated CADfix with Tech Soft 3D’s HOOPS.

Check out this Designed with Cadence video about the Raspberry Pi. (Remember when we wrote about installing OpenFOAM on a Raspberry Pi?)

Was released…

I’m just gonna end abruptly here with this image from Dr. Abstracto on Twitter. Because when I was scrolling through my Twitter feed, I came to an abrupt and prolonged stop when this appeared.
