Goodmorning to everyone,

I have got a stupid problem with OpenFOAM that I show you in the picture. When I run in serial it doesn't give me problems but when I run in parallel he gives me this problem but the solution is the same. Can someone help me?

No one has got a solution for this problem?

Apparently this is related to docker and should not be a problem. This issue is discussed here. Try to set

export OMPI_MCA_btl_vader_single_copy_mechanism=none

before running the parallel application and see if the error messages go away.
