Hi,
I am trying to a run a simpleFoam calculation of a flow around an object. When I start simpleFoam it is just not continuing the caluclation: Code:

So I figured out the problem was that my object was not watertight. So during meshing snappyHexMesh also meshed the interior of the object and introduces some really bad cells there. This led to the crash of the calculation.
