Hi all,

I'm quite new to OpenFOAM and CFD in general, but have successfully been able to solve a scaled-down problem using interPhaseChangeFoam.

Now as expected performance is an issue with the full scale model and as I don't have access to an adequate computing infrastructure, I was considering my RTX 3090 GPU as an alternative. I've done a quick GPU vs. CPU comparison using RapidCFD with CUDA and saw a runtime reduction by roughly 70%. While this is a promising result, it appears the interPhaseChangeFoam solver has not been implemented for GPU/CUDA usage in RapidCFD yet.

Now unfortunately my expertise is far from being adequate to attempt implementing it myself so my question is: is there currently any way to get interPhaseChangeFoam working with GPU/CUDA out of the box or at least without extensive expert knowledge?


Any suggestions very much appreciated!
Stefan
