Hello everyone. I'm new to OpenFoam and I only started using it a few weeks ago. I am trying to run a simulation for propeller using pimpleFoam. I have created the mesh in snappyHexMesh however I'm getting this error when I try to run the simulation. I have tried with serial and parallel MPI and it's still giving the same error. I have attached the error code and boundary files.

Please help me figure out where the issue might be. Thank you.

Hi
the error is a floating point exception, caused by division by 0.
So most likely, somewhere in your case, there is a 0 where it shouldn't be.
