Hi,

This is my first post and I am new to the world of OpenFOAM. Last weeks I have spent watching video's and trying to run different tutorials. Right now I have a problem with trying to solve the problem with interFoam in parallel. So I am able to mesh and solve on a single core without any problems.

In order to speed up I started to look into using parallel processors.
First, I tried to get the meshing to work in parallel. Which I managed to do! I had to change the write precision from 6 to 7 since it was trowing an error about this.

Next, I want to solve the problem using interFoam in parallel, I have checked on how to do this but until now without succes. With a single core I do get it to work. The problem always is something with
Code:
MPI_ABORT
but I have no clue on what I am doing wrong.

I have included my case and hope someone can help me to resolve this.
Please note that the script I use to run is tailored to work on a PC cluster at my graduation company.

Thanks in advance!

PS I found this on the forum to use to debug but I don't know what it is exactly/
Code:
# mpirun -np <NPROC> bash -c "ls -l" 
# mpirun -np <NPROC> bash -c "export"
