I've been trying to run some studies on Rocky but the estimated time is impracticable. I'm currently using my CPU 16 processors to run the study because when I try to run it on the GPU (RTX 3060) it gets super slow.

The software is not built to work with the 3060? Only with the RTX 3080/3090?

An RTX A2000 would be a great buying option to run the studies?

Hi Rodrigo,

RTX 3060, RTX 3070, RTX 3080, RTX 3090 and RTX4090 are supported

PROS: Faster when using only spherical particles and/or SPH elements.

CONS: Slower when using shaped particles. For better results, use only the above recommended GPU cards during Rocky processing.

Note that Gaming cards can have good performance when running small cases with spherical particles and/or SPH elements but may not be the best choice for simulations with shaped particles.

Different GPU cards can have one order of magnitude difference in performance.
