Is it possible to have self-contained FEM on each submesh?

+6 votes

Hi all.

I made the same query earlier last month, but unfortunately I didn't get answer. I work with non-overlapping domain decomposition methods (FETI methods specifically) and I need separated local stiffness matrices, etc. (FEM data), for corresponding parts of the global mesh. The original problem with global stiffness matrix is partitioned into smaller problems with local stiffness matrices, which is solved in parallel. So the question is: Is it possible to perform decomposition of the original (global) mesh into (local) submeshes and perform self-contained FEM on each submesh concurrently?

Thanks for any response, it is very important for me.
