Well, I am working with fracture creation in between mesh elements. In this case I believe it sort of makes sense to have 'strong' BCs and internal discontinuous DOFs being tied together by interior penalties... (not sure though)
I think strong BCs will hurt your convergence rates, but you should still converge, so it couldn't hurt to try and see if I'm wrong.
I was considering to duplicate the DOFs myself during topology creation: I would add triangles sharing vertices _coordinates_ but not vertex _references_. Then I map the neighbors and tie them together during assembly. Would that be sound?
Gah. At that point you'd have to add manual constraint equations between your solution triangles and the duplicate triangles the constrained boundary DoFs, so you might as well add manual constraint equations between your solution triangles and the desired boundary values directly. --- Roy ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Libmesh-users mailing list Libmesh-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/libmesh-users
