Hi Foamers,

I am running an analysis using rhoPimpleFoam in OpenFoam 4.1 and for the first time I have encountered a rather strange problem: the code stops right after writing the first field averaging and doesn't give any errors. It just stays like that, stuck in the iteration.

I have the following log the moment the run gets stuck:

The mesh is unstructured and 3D, I don't know if this has any meaning but I've never had this kind of problem with structured mesh. I am currently working with unstructured tetrahedral grids.

You can find my controlDict in the attachments, thank you.
