Our customer faced one problem that pyFluent on Linux stopped suddenly.
But they can finish same data on Windows.
They checked followinfgs;
- AMD and Intel CPU & Intel-MPI(2012&2018)-> same
- 1 core and multi-cores -> same
- Checking with Top, the status is "S". (usually R).
I have no idea what is causing this and would like advice on where to start.
Could anyone advise me?
