Let’s get Navier-Stoked because it’s Friday and time to review recent news from the world of computational fluid dynamics. I want to draw your attention to a few specific articles beginning with the importance of stupidity. In case you couldn’t join us on the island of Maui for the 11th International Conference on CFD [humble brag], the proceedings are now online and will provide a weekend’s worth of reading. Also be certain to spend time with misconceptions about FEM and Jack Dongarra’s keynote on HPC. Shown here is a computational electromagnetics simulation of a B-1 aircraft performed on a Gridgen mesh from way back in the day.

The times of drawing ships by hand are over as CAD vessel designs become more complex to reduce fuel emissions. Though maritime transport is one of the most energy-efficient modes of transportation, it is also a large and growing source of greenhouse gas emissions – 1,076 million tons of CO2, which is ~2.9% of global emissions caused by human activities.
Hi, I’m Reza Djeddi and I’m a Lead CFD Application Engineer at Cadence Design Systems. Some of my friends call me “The Jedi” because of how they think my last name is pronounced and the fact that I’m a big Star Wars fan, but it’s actually pronounced more like “jeddy” (though I wish I were an actual Jedi). I earned a Ph.D. in Mechanical Engineering as well as an M.Sc. in Aerospace Engineering from the University of Tennessee Knoxville. Before joining Cadence, I worked as a Research Assistant Professor in the Mechanical, Aerospace, and Biomedical Engineering Department at UT-Knoxville for four years where I led NSF/DoE/DoD-funded research projects with my former Ph.D. advisor and mentor, Professor Ekici.
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.

Through further enhancements to our Flashpoint goal-oriented and intelligent automatic surface meshing framework and a new automatic volume meshing mode, one can continue to build upon established best practices throughout all stages of the meshing process. In addition, we have substantially improved viscous volume meshing performance with a new advancing layer technique that when coupled with our optimization-based volume smoother leads to improved mesh quality and robustness for your simulations.
