Hi there,

I am using sprayFoam on a work station and am facing irrational computation time for 1 second of simulated real time. With about a million cells I get 120 secs out of a day with 16 cores @ 3.1 GHz.

Has anyone already made experience with GPU computing? The workstation is equipped with an Nvidia Quattro and I'm really expecting a high speed-up if I can use GPU acceleration for my computations.

Am I right and how does GPU computing in OpenFOAM work?

Thanks a lot.

Best, Robert
