[Gmsh] CFD mesh with prismatic boundary layer based on STL

[Johannes Dillinger]

Dear all,

still didn't have any luck in meshing the STL with prismatic sublayer..
Either the tetrahedra mesh directly connects to the wing surface rather
than to the prisms, or the tetrahedra are not generated at all due to
intersection issues.
Maybe someone has another hint on how to modify Ruths file to make it work..
Thanks a lot in advance, kind regards,

Johannes
