Problem with SnappyHexMesh and force monitoring
 

Hello OpenFoam users.

Just wondering if anyone else is facing an issue with unrealistic force monitor output that occurs when executing snappyHexMeshing in parallel. My code solves with no issues in pimpleFoam and the forces calculated in paraFoam are reasonable, so its not an issue with the solver or the case setup. But the forces generated by the force monitor in forces.dat are off by several orders of magnitude. The issue resolves when running the case with snappyHexMesh in serial.

The following warning appears in SHM parallel:

From function Foam::treeBoundBox::treeBoundBox(const Foam::UList<Foam::Vector<double> >&) in file meshes/treeBoundBox/treeBoundBox.C at line 136 cannot find bounding box for zero-sized pointField, returning zero

Any insight would be greatly appreciated
