Dear all,

I am trying to calculate a base flow with the steady-state solver using selective frequency damping.

Recently, an error, shown in the picture below, was given when I tried to run in parallel the IncNavierStokesSolver for my new mesh-refined case using mpirun -np:

However, this error has never occurred before when:

1.using serial running for the same session file/ setting of this mesh-refined case;

2.using parallel running for other cases so far, which are all with much coarser meshes;

So I want to know what triggered this kind of problem and how to deal with it.

Thanks in advance for the help.

Best regards,

Mona.
