Hi all,
I am using Python and numpy libraries inside OpenFOAM, and I use a Python module to calculate density instead of rho = thermo.rho() whatever we have that in reactingFoam solver. I had to define objects and arguments to make the module readable. for running an OpenFOAM code in parallel, I use the following command "mpirun -np 2 reactingFoam -parallel", but it doesn't work for the PythonFOAM case. and I see the following error,
"mpirun noticed that process rank 0 with PID 0 on node BOOK-SK5J7CQPFM exited on signal 11 (Segmentation fault)."
did you have any experience with parallel running?

Have you tried running in serial? Does it only fail when running in parallel?

What does your parallel setup look like? Do you have a decomposeParDict?

Thanks pbevington for your reply. I can run it in serial without any problem. For parallel running I do decomposePar first and after that mpirn...but it doesn't work. Maybe it is related to the ranks, but I don't kmow what should I do exactly.
