This week’s hoard of CFD miscellany includes several items that will require a deep breath and some time to digest. There’s an online interactive text on linear algebra, the International Simulation Olympiad for academia, a very cool video visualization of internal combustion, a survey about PLM status, a video about writing effective [Physician, heal thyself.], a podcast with me and Kenneth Wong, and all the software, application and event news that could be made to fit this format and the time allotted to writing. I just liked this pretty little picture of a mesh and a boundary layer velocity profile from our friends at GridPro.

Here’s your weekly reminder that your presentation abstract is due by 31 January for CadenceLIVE Silicon Valley 2023 (19-20 April). Share your Fidelity CFD work with others, learn best practices from them, meet the Fidelity CFD team.

In case compressibility in fluid dynamics is new to you, here’s what a shock wave looks like.

I’ve been quite open about the fact that I got through a BS and MS in engineering without ever having taken an linear algebra course. So Interactive Linear Algebra by Margalit & Rabinoff is quite nicely done if not 40 years too late for me.

CFD for floating solar arrays.

CFD for Chinese solar greenhouses. [I can only assume something unique about the Chinese variety, like the difference between an unladen African or European swallow.]

This is cool. The first Papua New Guinean to earn a PhD in mechanical engineering specialized in CFD.

Design of experiments, machine learning, CFD, and optimizing Formula 1 car aerodynamics.

Have you heard about the International Simulation Olympiad? It is “an online global olympiad to promote and celebrate the excellent computational (simulation) engineering happening in academia around the world, using open-source software.” You have until 15 Feb to register.

Our friends at Coreform launched Cubit Learn, a size-limited, freely available version of their meshing software.

The importance of mesh-flow alignment from our friends at GridPro.

For those of you interested in novel aircraft concepts, DARPA awarded a contract to Aurora Flight Sciences to build an aircraft that does not use mechanical flight controls.

The annual CIMdata PLM Status and Trends survey is for PLM practitioners who have experience implementing and using PLM strategies and enabling technologies. The goal is to deepen the collective understanding of the status, drivers, and preconditions for companies to achieve value from their investment in PLM. Why not spend 15 minutes sharing your thoughts?

Nuclear explosion impact on humans indoors. [Conclusion: duck and cover.]

Spend an hour and twenty minutes with Larry McEnerney, Director of the University of Chicago’s Writing Program, and learn The Craft of Writing Effectively.

I always enjoy a chat with Digital Engineering’s Kenneth Wong. And it’s funny that he turned our chat into a podcast because I never developed the podcast habit. So I haven’t listened to it and don’t know what kind of gibberish valuable insights I shared. I wish the adventurous and morbidly curious among you the best of luck.

Another one for aviation fans: I had no idea the USAF had a hypersonic air vehicle effort named Project Mayhem that “creates a vital avenue for the development of hypersonic aircraft, both military and civilian.” [Based on my experience back in the day on the X-30 when it was also positioned as dual-use, let’s just drop the civilian use positioning. We all know what it’s for.]

So here’s a Fluent article about selection of appropriate mesh type. Which raises the issue of what you call the mesh cells near a no-slip wall intended to resolve the boundary layer. Our friends at Ansys say “inflation layer,” the GridPro article cited herein uses the term “padding” which I have never seen before, my old friends from ICEM CFD [where are you Armin?] used to call it “bunching,” in Pointwise we just call it “clustering” or “viscous layers.” Do any of these resonate with you?

SC23 [aka Supercomputing 2023] will be in Denver on 12-17 November. Submissions are now open.

CFD for… sunglasses?

What’s new in Simcenter Mechanical Simulation 2212?

NASA Langley’s Computational Aerosciences team has an open position.

CFD for a yawn, I mean yacht.

This is truly for the hardcore mesher/geometer types. Meshing people understand that nasty geometry breaks a lot of things. But in this case, nasty geometry breaks some mathematical ideas about tiling (which is mesh-like).

P.S. I just realized that because my iPhone puts bookmarks in a folder called Mobile Bookmarks (as though that differentiation is relevant) while my laptop puts them in Other Bookmarks I’ve been neglecting some CFD items that may be getting stale. I’ll fix that next time.
