My implementation of the GaussSeidel smoother using a Diagnol direct access scheme in OpenFOAM as compared to the default GS smoother LDU gives almost ~50% improvements in cache misses and hits for a structured 3D cavity tutorial. Profiled using the amazing LIKWID profiler. Will share a deep technical report soon. Check it out and use - https://github.com/amartyadav/DIAGaussSeidel-Smoother-OpenFOAM

Released my DIA-format Gauss-Seidel smoother plugin for OpenFOAM v13. MIT licensed.

Replaces the default LDU smoother on structured hex meshes — DIA stores diagonal bands contiguously, reducing pointer indirection and DRAM pressure. Expecting 10–20% wall-clock gains and better cache utilisation based on standalone profiling. Full OpenFOAM benchmarks incoming.

My work for the month is to optimise the matrix adressing scheme of OpenFOAM to reduce cache miss. Initial idea is to replace the LDU Matrix addressing scheme with Diagnol matrix addressing scheme using multiple arrays for structures meshes. Will check it out on a simple 2D Poisson equation using Gauss-Seidel solver to check performance benefits, and will eventually proceed to introduce a new solver as a plugin if benefits are noticeable.
Wish me luck.

Might publish a blog or two in a few weeks about my work with OpenFOAM, different profilers, and an implementation of an LBM CFD kernel on RISC-V with POSITS.

What a great company to be working for. Learning so much!

I’m interested in active boundary-layer control (DBD plasma actuators), low-speed aerodynamics, and open-source CFD workflows on Linux. Happy to exchange ideas, experiments, and practical insights.

For users of #OpenFOAM your most used solver is: #hpc #CFD

Hace unos días se publicó OpenFOAM version 13, la distribución de la OpenFOAM Foundation (https://openfoam.org).

Se puede instalar en la última versión de Ubuntu (25.04) y en las dos últimas LTS.

En windows, se usa el Windows Subsystem for Linux.

En mac se usa Canonical Multipass, no tengo muy claro lo que es y me da pereza probarlo.

Otros Linux pueden requerir compilar el programa.

Getting a bit further with my exploration of Computational Fluid Dynamics (CFD) this evening. Using the mighty @FreeCAD 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 #CFD experts fancy a chat.... I HAVE QUESTIONS! #OpenFOAM #FreeCAD

Following on from my earlier stuff about being inspired about parachute/recovery systems and Ballute design in @FreeCAD I've dived into setting up the CfDoF workbench and bashing through a simple tutorial pushing water through a stepped tube. I think I borked the glyph a little, but I feel like I've learnt a little... and seen a LOT to learn. #OpenFOAM #CFD #Paraview

Fantastic to see this article about #FreeCAD and #OpenFOAM being used to perform CFD analysis on #rocket designs. Lots of mentions for Dave Carter who is a fabulous FreeCAD contributor and creator of the Rocket Workbench. Check out the excellent Peak Of Flight rocketry newsletter here https://www.apogeerockets.com/Peak-of-Flight/Newsletter641

@jk I can't tell why but this reminds me on #OpenFOAM 🙄 . The finite volume library is nice and people are able to do stunning things with it, but inherentency hell grows with every solver.

Anyone has a good OpenFOAM tutorial to recommend?
Entry-level please!

Really enjoyed chatting to Tim from @avian earlier this week. Their use of #python #freecad #openfoam and #openvsp is pretty amazing and creates fantastic flying machines! Check out the writeup on the @FreeCAD blog. https://blog.freecad.org/2024/07/30/forged-in-freecad-avian-hang-gliders/

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!

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

http://legi.grenoble-inp.fr/people/Pierre.Augier/fluidsimfoam-at-openfoam-users-conference.html

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:

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.
