Hello all,
I think I found a bug related to the extrusion (and recombination) of relatively small surfaces.
The problem occurs when you try to extrude very small 2-D cells into the third dimension while having a huge domain, like it is often necessary for a resolved boundary layer mesh for a 2-D airfoil simulation.
Gmsh then fails to recombine the extruded mesh into quadrangles.
You can test this with the attached minimal example. It creates the mesh well until you uncomment the last line. You can then see in the GUI statistics-panel, that gmsh created triangles, which is obviously not intended.

Best regards,
