Hello, I recently updated gmsh from version 2.6.2 to version 2.7.1. I'm really happy about a few improvements, but unfortunately a routine I used for several month without any problems stopped working: I have attached a geo-file for meshing a structured sphere (I just changed a file I've found in this list some time ago. I think somebody called Markus created it...). The variable 'aufl' is used to change the resolution of the mesh. For aufl=3 or aufl=4 the mesh is still alright. But when I set the value to 5 or higher, the meshes of a few surfaces include points on the opposite side of the sphere. This is somehow related to the order of the line loops, but I can't figure out why this happens or how to stop this. Any help to fix this problem is greatly appreciated. Thank you, Jakob
