Dear all,

I am running simulation of rotating propeller using pimpleFOAM solver on supercomputer cluster. Before uploading it to the cluster, I tried to run it locally using OpenFOAM V1906 and everything seems working alright. When the run was conducted on the cluster which uses OpenFOAM 5, I obtained zero residual for all of the variables, as shown in the figure below.

To get around the issue, my supervisor helped me to install V1906 on the cluster. The residual was no longer zero but an error related to the MPI process starts popping up in the midway of the run.

I have tried to identify the source of error but to no avail. I have consulted many people in the lab who have some experience in OpenFOAM, and all of them had no clue to what went wrong. Therefore, any form of help is greatly appreciated as I have been stuck for quite some time.

Feel free to raise any question should more information is needed. I am fine with sending a copy of my setup as well. Cheers.

First of all, OFv1906 and OFv5 are not the same.

Your error message suggests that zero-division error occurs.

Could you list the set of commands you execute? Or do you only execute the that tutorial?

Hi, in fact, this is a UAV propeller with serration design, which is meant to study its noise reduction capability.

This is the list of commands I used:

module purge
module load openmpi/gcc493/1.10.2
source /home/project/11000550/OpenFOAM/OpenFOAM-v1906/etc/bashrc
cd $PBS_O_WORKDIR
chmod 755 Allclean
./Allclean
blockMesh
surfaceFeatureExtract
decomposePar
mpirun -n 48 snappyHexMesh -parallel -overwrite > log.snappy
reconstructParMesh -constant
topoSet -dict system/createInletOutletSets.topoSetDict > log.topo
createPatch -overwrite > log.patch
checkMesh > log.mesh
decomposePar -force
mpirun -n 48 renumberMesh -parallel -overwrite

Do let me know if you require a copy of my setup. Thanks.
