In version 4.5.5 Gmsh creates a single surface in situations where version 4.4.1 created multiple surfaces.
Dear Gmsh developers,
If you load the attached file into Gmsh you can see, that the resulting geometry is different between version 4.4.1 and 4.5.5. dehd1_journal.geo In version 4.4.1, you get several surfaces at the outer cylindrical section. Each of those surfaces can be accessed separately. However, in version 4.5.1 there is only a single surface at the outer cylindrical section. It is no longer possible to access parts of the cylindrical surface (e.g. for applying loads).
Is there a way to change this behavior?
