Extrusion creates additional nodes in the external faces but not in the internal mesh
When I create an extrusion for a surface I get the following picture
Somehow on the outer face an additional layer is created which is not reflected in the inner mesh. I could not figure out how to make the extrusion consistent. The problem manifests itself when importing the mesh into OpenFOAM.
For the record, the extrude command I'm using is
occ.extrude(surf, 0, 0, depth, [1], recombine=True)
