concretedogGetting a bit further with my exploration of Computational Fluid Dynamics (CFD) this evening. Using the mighty <a href="https://fosstodon.org/@FreeCAD" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@FreeCAD</a> I've modelled this "Ballute" style parachute and simulated it descending at 6m/s in air. The air velocity is plotted in the images. Ace to see the turbulence in the point cloud/steam chaser view. If any <a href="https://mastodon.social/tags/CFD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CFD</a> experts fancy a chat....

FreeCADFantastic to see this article about <a href="https://fosstodon.org/tags/FreeCAD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FreeCAD</a> and <a href="https://fosstodon.org/tags/OpenFOAM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenFOAM</a> being used to perform CFD analysis on <a href="https://fosstodon.org/tags/rocket" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#rocket</a> designs. Lots of mentions for Dave Carter who is a fabulous FreeCAD contributor and creator of the Rocket Workbench.

Fedora Project (F42 is OUT)Here's a use case you don't hear about often - computational fluid dynamics. If that's something relevant to you, Linux has you covered with OpenFOAM! ➡️ <a href="https://fedoramagazine.org/use-openfoam-to-solve-computational-fluid-dynamics-problems/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://fedoramagazine.org/use-openfoam-to-solve-computational-fluid-dynamics-problems/</a><a href="https://fosstodon.org/tags/Fedora" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Fedora</a> <a href="https://fosstodon.org/tags/CFD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CFD</a> <a href="https://fosstodon.org/tags/OpenFOAM" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenFOAM</a> <a href="https://fosstodon.org/tags/Linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linux</a> <a href="https://fosstodon.org/tags/OpenSource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenSource</a>

FCLCI'll be speaking during the OneAPI dev summit tomorrow, specifically the panel discussion on accelerated computing. Partially as a meme/Sanity check the challenge of this afternoon: Can I got from no installs to a GPU accelerated simulation of OpenFOAM using an Arc a770 on Linux?Plan is <a href="https://mast.hpc.social/tags/OpenFoam" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenFoam</a> 2212, <a href="https://mast.hpc.social/tags/petsc" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#petsc</a> 3.19, <a href="https://mast.hpc.social/tags/OneAPI" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OneAPI</a> 2023.1 and <a href="https://mast.hpc.social/tags/mesa" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#mesa</a> 23 (in case I need to fall back to <a href="https://mast.hpc.social/tags/OpenCL" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#OpenCL</a>)

Stefan ZitzMy 🐘 <a href="https://julialang.social/tags/introduction" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#introduction</a> 👋 I'm a researcher at Roskilde University (<a href="https://julialang.social/tags/RUC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RUC</a>) in 🇩🇰. My background is <a href="https://julialang.social/tags/physics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#physics</a> and research I do revolves around <a href="https://julialang.social/tags/fluiddynamics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fluiddynamics</a> 🌊 💦 using <a href="https://julialang.social/tags/CFD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CFD</a> and <a href="https://julialang.social/tags/theory" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#theory</a>.
