Hi Gmsh team:
I am trying to generate a mesh by extruding a stl surface file. I always
get a warning message saying "Warning : Could not orient normal of surface
201". I checked the generated surface mesh for surface 201 for example. I
can see that the element surfaces are not on the same plane surface.
I have tried to keep the input stl clean in the sense that the boundary
loops are on the same plane surface. However, I still get the same warning.
I put the .geo, .stl, and error log info in the folder here:
Do you have any suggestions?
Thanks a pile!
