Serial processing work, but not parallel. Everyone has any idea?

Hello,

I'm using also fsiFoam to run a case, however, still no solution for parallel simulation with that. Could you please let me know did you find any solution?

more or less same error:

[2] --> FOAM FATAL ERROR:
[2] Cannot find file "points" in directory "constant/solid/polyMesh"

Thanks
