Hello everyone,

I'm having a problem that possibly caused by parallel running. I'm running my case using the solver rhoSimpleFoam, the case runs perfectly in serial, but it won't run in parallel, the error message is as followed. I'm a beginner of OpenFoam and I don't know what causes this problem, could you help me to solve this problem?

Thanks a lot

Did you solve this problem? I am also getting almost same problem while running chtmultiregionsimplefoam.
please please reply.
