Question for the @precice people:

I have used #precice with #openfoam and #calculix in the past with an aim to use it for arterial flow simulation.

I now have a new PhD student starting in October. How far out is version 3? Looking to couple to Calculix or Solids4Foam.

@dlb sinon, vu que tu utilises Freecad,, y'a un super plugin pour la CFD (https://github.com/jaheyns/CfdOF), que j'avais testé avec succès il y a deux-trois ans. Il a dû faire beaucoup de progrès depuis. C'est basé sur #OpenFoam (qui est à installer par ailleurs). M'enfin, ça reste de la CFD, et c'est pas fait en trois coups de cuillères à pot.

#OpenFOAM ver.11 リリース🎉

https://openfoam.org/release/11/

The @of_ws #ofw18 (that is the #OpenFOAM Workshop) is starting
The location is cool. But unfortunately not very cool

Looking forward to the talk at 18th OpenFOAM Workshop later today on "Parameterized cases with pyFoamPrepareCase" . #OFW18 #OpenFOAM @of_ws

まあこんなもんか。これで記事書く。 #FreeCAD #OpenFOAM

#OpenFOAM 境界条件テスト、メッシュ粗め。

とりあえず流入は体積流量指定で良い感じに安定する。

The development branch of #swak4foam compiles with the latest #OpenFOAM release v2306 from ESI (but also v10 of the Foundation and foam-extend 5 work)

The "Universal #OpenFOAM build scrpt based on Ansible" https://openfoamwiki.net/index.php/Installation/Ansible has a new release and supports the recewntly Released #OpenFOAM version 2306 from ESI (and also the v10 from the foundation branch and version 5 of foam-extend)

#Fluidsimfoam was demoed at the recent a #OpenFOAM users conference. Slides and blog post by @PierreAugier here:

On the topic of #CFD solvers, #OpenFOAM is popular choice. We are actively working on creating a new reusable #Python + #FluidSim framework, so that you can define, launch, manage and post-process :blobhaj_plead_1: OpenFOAM simulations from Python :python_logo:

Interesting? Take a look

The feature I miss the most from Twitter on Mastodon is quote tweets, explicitly of my own for the use case of related but divergent technical threads.

Working on the #GPGPU && #AVX512 accelerated build of #PETSc to enable faster execution of #OpenFOAM as of now and all the relevant threads would have to be independent threads and hard to cross reference as new threads/tangents pop up.

Last week, I was at the #Coupled2023 conference in Chania, Crete, Greece. It’s amazing to see what people can do when it comes to #CFD #particle coupling or fluid structure interactions (#FSI). Also quite interesting the sessions on #preCICE , #openfoam and #opensouce

Shout out to Konstantinos and @roenby who gave a fascinating talks on emulsions and FSI. Thanks to Konstantinos and @roenby I have pictures from my talk

I'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 #OpenFoam 2212, #petsc 3.19, #OneAPI 2023.1 and #mesa 23 (in case I need to fall back to #OpenCL)
