Okay. Here's what I'm trying to do overall: I have 2 meshes, 1 for Poisson and 1 for Schrodinger. The Poisson mesh is over a big domain, and Schrodinger mesh lies only in a small region inside it.
I locate Poisson quadrature points inside Schrodinger mesh, because that's where I need to evaluate solutions of Schrodinger mesh. Now, since the Poisson mesh is quite big, all the quadrature points which lie inside Schrodinger mesh are usually are on a small number of processors. I need to distribute these points among processors according to the Schrodinger mesh partitions. What's the best way to ghost elements and solution vectors in this case? Thanks!
