I have a similar question: I want to couple dofs between two meshes. They have
a shared surface (shared in the sense that it is at the same location). I
assemble my system blockwise. The one mesh describes the "inner" domain I use
in multiple situations and the other mesh is a pml domain I only use to
truncate sometimes. I want to build an affineconstraints object to couple the
surface dofs together but I'm running into problems, especially dealing with
orientation (nedelec elements, so the edge orientation plays a role). Is there
a library implementation (I couldn't find one and functions like
interpolat_to_different_mesh() are only for the communication of surface
values, not to construct constraints.)
I have built an implementation myself but it is an error prone process and I
would prefer to use as much of the library code as possible.
Do you have any pointers for me?
I don't think there is anything in the library itself for this case :-( Why do
you want to use different triangulations/DoFHandlers for the two parts of your
domain? I think that pretty much everything you would need to keep everything
in one mesh is already there.
