This week’s agglomeration of CFD flotsam and jetsam is chock full of wonderful images including an “image of the week” that qualifies for “image of the year.” There are several articles involving ML including one that’s cautionary. There are also links to several longer texts that some might find useful. Finally, Flipper gets the CFD treatment and the viscoelasticity of ricotta cheese gets way too much treatment. Shown here is one simulation from a study of supersonic swirl mixers that you’ll find inside.
And we’re off.
- You’re aware of “the world’s foremost repository of structured knowledge and advice designed to underpin quality and trust in the industrial application of CFD,” right?
- A beginner’s guide to the finite element method.
- Improving wall-modeled turbulence with ML.
News from Fidelity CFD
- We have two new webinars on tap for next week.
- Wed 21 Sep – Predicting Aerodynamic Flow Around Automotive Vehicles. We’ll be comparing RANS, RSM, and some scale-resolving approaches.
- Thu 22 Sep – Accelerated CFD Meshing with Fidelity Pointwise. We’ll be demonstrating the latest capabilities of our Flashpoint suite of automated meshing tools.
- Come see us at these conferences.
- Red Bull Racing Formula 1.
- an articulated container barge.
- swirl flow in supersonic separators.
- aerosol jet printers.
- patterned surfaces and sedimenting particles. [Fluid dynamics, not CFD]
- leaks in pipelines. “The team will use Computational Fluid Dynamics (CFD), whereby AI simulates the flow of liquids and gases…”
- piston bowl optimization.
- ammonia-powered aircraft engines.
- cavitation in pumps.
- LNG-powered containerships.
- GiD v16.1.0d
- Autodesk Fusion 360 Simulation Workspace. “The ability to run simulation studies on a local computer will no longer be an option for simulation solving.” [Is it just me, or does this sound like a bad idea?]
- Parasolid v34.1
- Quanscient’s early access program is open.
- Beta CAE v23.
- Ansys 2022 R2.
- Here’s an announcement of the 18th OpenFOAM Workshop next summer in Genoa, Italy from its host. The official website remains here.
- exaFOAM Summer School, for HPC applications of OpenFOAM, will be held in Bologna, Italy on 17-19 October 2022. [Summer school? In October?]
- The 6th DualSPHysics Workshop will be held on 25-27 October 2022 at the Polytechnic University of Catalonia. [Forgive my poor translation of the Spanish.]
- Intel launched their first GPUs, Intel Arc Pro A-Series, that are said to be good for CAD workflows. Here’s more on that from DEVELOP3D.
- If you’re interested in AI for CFD, byteLAKE has shared an extensive bibliography of their work.
- There’s a lot to digest in this announcement from the White House, but efforts are being undertaken to ensure that tax-payer funded research is published quickly and openly. [I’m curious what you all think about this. Is it a big deal? Will it change how you work and publish?]
- The guy who never took a linear algebra class recommends to you The Art of Linear Algebra by Kenji Hiranabe.
- And while we’re on the topic of books, it looks like Lutz’s Learning Python is available online for download.
- And more reading because who needs sleep or weekends? Mathematics for Machine Learning by Thomas from 2018.
- And before we get all hot and bothered about ML, take a look at Leakage and the Reproducibility Crisis in ML-Based Science. [We are not without blame here. I would say we have a reproducibility crisis in CFD.]
- This one you’re gonna have to buy: CFD Modelling for Waste Water Treatment Processes.
- Our friends at Ansys continue to deliver solid financial results with Q2 revenue of $474 million and profit of $99 million. Here’s what Monica Schnitger had to say.
- Who’s interested in this? “We have assembled cloud GPU vendor pricing all in one table, sortable and filterable to your liking!” [I’m not doubting its utility, just curious about who needs this.]
- The hidden costs of data translation.
The Shape of an Image
While it should be quite obvious what drew me to Liz Deschenes‘ work, what made me dig deeper is that she is a photographer and the elements of the work below are photograms.
Bonus: Lasagna as only a science person could make it.
