Hello,
I was performing an incompressible simulation on a FSAE sidepod with radiator, when i got the following error on my simulation. “An unexpected error happened during mesh generation. Please contact our support for assistance.”

According to the investigation, this error only happens with Snappy and it means that the mesh is geometrically different from the model. In this case, the regions around the fan are very coarse and the mesh has holes.
The solution here is that you refine the mesh in critical areas. Making a flow volume extraction and using the standard mesher is highly recommended.
