This Week in CFD

This week’s aggregation of CFD bookmarks from around the internet clearly exhibits the quote attributed to Mark Twain, “I didn’t have time to write a short letter, so I wrote a long one instead.” Which makes no sense in this case because due to the magnanimity of my employer, we have a 4-day weekend to celebrate (in the U.S.) the President’s Day holiday. Shown here is a high pressure ratio centrifugal compressor from the Fidelity CFD 2022.1 release.

Mathematicians have proven Batchelor’s Law for the patterns (turbulence) in moving fluids.

The symposium on Progress in Computational Multiphysics Using Open-Source Software will be held in conjunction with COUPLED 2023 on 5-7 Jun 2023 in Greece.

CFD for an uncrewed air vehicle. In which we learn that “On an uncrewed fighter like Fury, proper integration of propulsion flow-path is the most significant design driver for overall vehicle.” [Propulsion flowfields are how I got my start in the aerospace world.]

Intelligent Light announced the release of their new software, IntelliTwin. “As a backbone for Digital Twin, IntelliTwin┬« is a Digital Thread which manages data provenance and workflows for projects.”

Tecplot shares their thoughts on faster visualization of higher-order finite-element data.

Ansys 2023 R1 was released.

Cadence (nee Future Facilities) released 6SigmaDCX Release 17.

I don’t know why I share these market forecasts but here it goes anyway: the CFD market is expected to grow at a compound annual growth rate of 8.8% through 2026.

CFD for a superyacht.

Lagrangian coherent structures, a new method to identify stress in polymeric fluids.

This is cool. New in CGAL is Alpha Wrapping, which addresses “the problem of generating a watertight and orientable surface triangle mesh from a given defect-laden input.”

Rhino 8 WIP has a new ShrinkWrap command.

CFD for greener aircraft.

CFD for additive manufacturing.

Airbus, DLR, and ONERA are developing a new, “industry-ready” CFD code. [Anyone know its name?]

In case you’re having trouble sleeping, Digital Engineering’s Kenneth Wong and I had a nice chat about the evolution of CFD and he made a podcast out of it.

CFD for a liquid hydrogen carrying marine vessel.

CFD for waferscale architectures? [At first I thought it said “wafflescale” which got my attention. But now I’m trying to figure out where waferscale fits relative to exascale.]

Register for this webinar on marine CFD coming on 23 February: Self-Propulsion CFD Simulations: Get Them Right and Fast

Fluids and thermal behavior have a lot to do with how things taste to us. But this article is less about the science that makes chocolate tasty and more about the 3D printed tongue with papillae detail.

CFD for indoor radon ventilation.

Why validate your CFD software? Does that question even have to be asked? Here’s a validation study of AirShaper versus other CFD codes for a Cessna Centurion.

Join us in Bengaluru on 15 March for CadenceCONNECT CFD Technology Day for Automotive Design.

CFD for a throttle check valve.

Engys released Helyx v3.5.2. And Streamline Solutions (an Engys venture) released Elements v3.5.2.

As seen on Twitter. This screen capture of a video showing the breakdown and dynamic behavior of gravity-driven rivulets from the CFD Lab at UniBw_M is really cool.

Paint is a fluid. There’s no rule saying you have to apply paint with a brush. You can spray it. You can fling it like Jackson Pollock. You can pour it like Morris Louis. The latter’s paintings certainly require a lot of practical knowledge of the fluid properties of paint and how to control rivulets of that paint as in Beta Mu from the collection of The Modern Art Museum of Fort Worth. Read more at the artist’s website.

Bonus? Drag Reduction for Swimming Shrimp [Those things just look nasty.]

    Thanks to those of you who replied with the name of the CFD flow solver being developed by Airbus, DLR, and ONERA. It’s named CODA which is another acronym for Cfd for Onera, Dlr and Airbus.
