Segfault when using surfaces in multiple axial_mesh components

[2xB]

When using surfaces in multiple axial_mesh components, it is possible to get a segmentation fault from

.

TODO:

• Understand why this causes a segmentation fault in the first place.
• As discussed with @richeldichel , one should get an error when adding the same surface to two meshes since overlaying meshes don't make sense.
