I made a wedge mesh using salome and converted to openfoam using unv, and ran a test case.
Then, it showed such sigFpe error, exploding velocity values over 1e35 I also made full 3d mesh which is same geometry as revolved wedge mesh, and it worked fine. Therefore it seems like problem to mesh, not solver setting. Wedge was rotated 5 degree, and form shape of nozzle. It isn't single layer wedge, and mainly tetrahedral due to salome setting and ease for converting What could be the solution? Wedge is already 5 degree so increasing angle seems impractical... Code:

What does checkMesh say? Is it happy with the mesh?
