Dear gmsh team,
I would like to switch orientation of surfaces coming from a part design by
FreeCAD and export in step format.
- I try to reverse normal orientation in the FreeCAD (MyShape.reverse() ??) but
in gmsh nothing change (however I am not sure of how is made the export in step
and if step can store inward normal vector....)
- I try the "classical" gmsh version :
Physical Surface (1) = {-SufList[]};
It works for .msh format (native gmsh) but in .mesh (inria format) only the
label is change into -label but the orientation remain the same...
- flip all mesh normal is not possible because I have other shape in my mesh,
not concerned with this problem.
Do you have an idea ?
Thanks!
Benoit
ps : In .msh format, I observe that if the surface has strong variation close a
small inner corner, the element orientation may be random close to the inner
corner if there is only one element on the corner thickness.
