I am using the following script for mesh generation only. Want to run snappyHexMeshan topoSet in parallel:

nProc=32
cp -rf 0.org/ 0/

blockMesh &> log.blockMesh
decomposePar &> log.decomposePar
mpirun -np $nProc snappyHexMesh -parallel -overwrite &> log.snappyHexMesh

mpirun -np $nProc topoSet -parallel &> log.topoSet 

# reconstructParMesh -constant &> log.reconstructParMesh

If I run the reconstructParMesh at the end, the reconstructed mesh opens up in paraFoam without problems. But if I want to check individual mesh partitions in processor directories, i.e by running

paraFoam -case processor2

, or run a solver in already decomposed mesh without reconstructing, i.e. by running

mpirun -np $nProc pimpleFoam -parallel &> log.pimpleFoam

, I get the following error:

[2] --> FOAM FATAL IO ERROR:

and this goes on for almost all processor neighboring faces. What is the reason and how can I overcome this? Here I have read that these lines are necessary:

ls -d processor* | xargs -i cp -r 0.org/* ./{}/0/ $1

but not sure where to use them and why?
