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: https://www.dropbox.com/sh/4ugzuf2vzdxz95x/AAAqxtD1eTs_4hH39Vl4J6tna?dl=0 Do you have any suggestions? Thanks a pile!
