Enabling hardware acceleration in Fluent with Geforce

Sebs · May 3, 2021, 16:54

Long story short, I have 2 RTX 3080s, which I would love to be able to use for Fluent as well - but officially only Quadro and Tesla GPUs are supported. Is there a way around that??

Depends on which solvers you are using. Last time I tried, you could just enable GPU acceleration with any Nvidia GPU, recommended or not.
But for those solvers where GPU acceleration can not be activated through normal means, enabling it anyway will just make things run slower. There are ways to do it via command line. I don't remember the exact command, but it's probably not worth the 5-minute google search
