face 198 area does not match neighbour by 0.0076471% - possible face ordering problem.įrom the error message, we can see that it is quite sure that snappyHexMesh successfully recognises the background mesh as a 2D one, so far so good. Please check the geometry or adjust the orthogonality tolerance. The number of points in the mesh is not equal to twice the number of edges normal to the plane - this may be OK only for wedge geometries.

#OPENFOAM WEDGE PATCH SERIAL#
This works just fine when you mesh on a serial processor, but when one tries to do the same meshing process in parallel, snappyHexMesh would give the following complaints and lead to a fatal error. Similarly, an empty boundary type can tell snappyHexMesh don't bother to mesh in the perpendicular direction. When setting up the 2D simulation cases, the boundary condition of frontAndBack patches should be set to empty to prevent OpenFOAM from doing calculations in the third dimension.

The key process is extrudeMesh, which extrudes one patch for a certain distance after the 3D mesh is generated.
