I have a geometry where more than 2 surfaces can intersect, so there are edges that belong to more than 2 triangles (in this case, the tags of all the triangles are different).
When I use mmgs, the resulting mesh is not correct on those edges (the left image is the original mesh, the right is the mmgs result).
The files are here:
geom_1_before.mesh (60.3 KB)
geom_1_before.sol (2.3 KB)
Should mmg be able to handle such cases?
