What I really need is the solution in the interior (FE_DGQ).

I am trying to separate (FE_DGQ, FE_FaceQ) into (FE_DGQ, FE_Nothing) and (FE_Nothing, FE_FaceQ)  and hope in this way I can only transfer solution on FE_DGQ. But I have no luck yet.

What specifically happens?


On the other hand, can you recommend any reference on how to transfer the solution by hand.

You should be able to define a DoFHandler that *only* has the FE_DGQ, copy the solution into a vector associated with that DoFHandler, and transfer that from one mesh to another. Then reverse the process once you're on the other mesh.
