This Week in CFD

This is the first CFD news roundup of 2022 Q2 and it comes with the implication – or at least hope – that everyone’s Q1 was productive. We’re meshing a lot of rotating machinery this week, we have several job openings to share, new events in the calendar (including CadenceLIVE in Silicon Valley where we hope to see you), and a truly eye-catching image of the week. Shown here is are non-linear harmonics for a multistage axial turbine, a method that accounts for the effect of incoming flow perturbations.

Registration is now open for CadenceLIVE Silicon Valley on 8-9 June. Come learn about the latest from Cadence CFD.

BosonQ Psi announced the release of BQPhy for quantum simulation. See a demo video and/or sign up for a demo.

Read about combining structured and unstructured grids on the Cadence CFD blog. [Is it just me or do you see swiss cheese too? Mmmm. Cheese.]

See how Renault uses Cadence CFD for turbochargers and more to reduce CO2 emissions.

Who’s hiring?

I just like this image from the website of the Conference on Engineering Design Optimization. See link below. Image from

Prof. Santosh Ansumali advocates for use of the Lattice Boltzmann method for aerospace applications in this 20 minute video.

Our friends at Ansys extol the benefits of GPU acceleration of CFD. [I am curious why the external automotive flowfield in Figure 1 differs for the CPU and GPU versions of the code. Different levels of convergence? Different number of convective passes? And how do these visual differences manifest in terms of engineering quantities?]

Here’s some gentle nightstand reading: Summary Review on the Application of CFD in Nuclear Power Plant Design.

I’m a sucker for a grid pic and our friends at GridPro always deliver structured grids that I’m very fond of due to how I started my career. This one is from their article about scroll compressors.

It’s very frustrating to visit a website that purports to provide simulation software for aerodynamics but not being able to determine, despite a lot of words, what they actually offer.

I don’t usually mention webinars here but Hexagon’s Perform multiphysics CFD simulations that are within 2% of physical experimental results caught my attention. [When did we stop capitalizing all the words in a title?]

OpenVSP 4.1.22 was released. Or was it?

IMAGE OF THE WEEK: PyFR DNS simulation of a triangular helicopter rotor blade operating in the Martian atmosphere. Screen capture from Website has link to the full technical paper.

The ASMO-UK 12 / ASMO-Europe 1 / ISSMO Conference on Engineering Design Optimization is coming up this summer, 18-19 July, at the University of Leeds.

I would’ve shared an article about thermal simulation of electronics if the website hadn’t been horribly ad-laden.

It seems that Wordle and its many variants (Nerdle, Heardle, Fibble, etc.) are everywhere these days. I don’t know whether it’s related but the Twitter account @5x6art represents artworks in a 5×6 grid of colored squares. Well worth following if you’re of the Twitter persuasion.
