How to reduce run time?

Mugen996 · May 12, 2020, 12:58

Hi all,

I need to run around 3000 openFOAM cases and I'd like to get the results sooner than later. At the moment each run takes roughly 2 minutes so I'm looking at roughly 100 hours of processing time so I'm looking for ways to decrease this run time.

My main question would be if its possible to do runs in parallel? But I'd also love to hear any tips or tricks you guys may know on how to optimise my workflow.

My specs:
CPU: Intel(R) i5-4690K @ 3.50GHz
GPU: GTX 1070
RAM: 16GB DDR3

you can parallel run one case or start multiple cases at once.
