This kind of mesh sounds like zero thickness cohesive element. But I am
not familiar with this method’s implementation. Does that mean I need
create two |Triangulation| objects?
No, not necessarily. I think you will want to look at lines 1346-1424 of
step-14 to see how you can create a mesh out of given vertices:
https://github.com/dealii/dealii/blob/master/examples/step-14/step-14.cc#L1346
As I mentioned upstream, you can just put multiple vertices at the same
physical location and make sure they belong to different cells. The
domain is connected between any two cells if all of the vertices of the
two cells' faces have the same vertices (not the same vertex locations),
and so you can create a "crack" in the domain by having separate
vertices there that are at the same location but logically separate.
