I have a bash script which executes OpenFOAM and later kills the Virtual Machine once OpenFOAM gets done even if OpenFOAM results in an error. But for this particular case / error, the Virtual Machine never gets killed and is stuck at OpenFOAM even though OpenFOAM logs reveal an error and OpenFOAM processing being stuck. I guess it's because OpenFOAM never exits? Not sure.

My bash script looks similar to below:

echo openfoam started
mpirun --allow-run-as-root -np 4 simpleFoam -parallel &>> log.txt
echo openfoam ended
# VM termination commands go here

Also find attached log.txt which logs OpenFOAM output.

What is the best way to know that OpenFOAM is stuck with some error and has stopped processing and I should go ahead and kill the Virtual Machine from bash?

And why does this script work for all other cases even when they result in an error but fails with this particular case?

Thanks in advance.
