I have been porting kernels from OpenFOAM for CFD to FPGAs using HLS as part of an internal research and engineering project at my company.
Spent 3 weeks debugging. The fix was awfully trivial.
No LLM could help me. I know my job is safe.Also, Microchip have bad documentation. They can do better.

Porting some OpenFOAM hotspots to FPGA using HLS. Starting with the dotInterpolate function.
My first such project. Also, a first for my company.Will keep you all posted.

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. -
The submission deadline for abstracts and training courses has been extended to March 15 to fill the last places in the programme.

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!

Cập nhật mô phỏng đối lưu tự nhiên và bức xạ tích hợp cho đèn LED COB 200W dùng OpenFOAM. Kết quả: nhiệt độ tản nhiệt cao nhất ~78°C, gặp khó khăn trong tính toán viewFactor (chậm), mô hình P1 chênh lệch ~6-8°C. Tìm lời khuyên về tiếp cận TIM chính xác và điều kiện biên ổn định hơn.

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

CW: No stoopid computers today, just riiiide
@ProjectPhysX Now we need a 3d scan to include as part of #FluidX3D to serve as the equivalent of the #OpenFOAM motorbike example!

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!
