Hi All,
The following would produce correctly oriented surface normals in gmsh 3.0
(surfaces 1 to 277 form a "half-shell" of my symmetric part):
new_surfs[] = Symmetry {1, 0, 0, 0} {Duplicata{Surface {1:277};}};
Physical Surface(2) = {1:277, -new_surfs[]};
The minus before 'new_surfs' was necessary to flip the normals in the mirrored
surfaces. However, in gmsh 4.0, it does not produce the desired result anymore
and the normal of the mirrored half now all point inwards. Removing the minus
has no effect.
I'm using the 64 bit windows binary.
Any suggestions would be appreciated!
Best,
Daniel
