Oggetto: [Gmsh] Issues with OpenCascade


Hullo everybody,

I find the following issues when using OpenCascade:

1) I start from the geometry of the attached test_00.geo: one cube, with a cubic hole;
2) Now if I want to apply a rotation to the inner cube (test_01.geo), I obtain that only the edges are rotated, and the original cube is conserved. This does not happen when the built-in geometry kernel is used (the applied rotation does not modify the surface loops that define the volume);
3) On the other hand, if I first apply the rotation (test_02.geo) and then define the volume (test_03.geo), the inner surface loop is not recognized as a closed volume.

Is there some way to work this out? Especially point 2) is an issue for me, as for my application I'd need to append the rotation command at the end of the geo file (i.e. after volume has been defined).
