Hi, I am working on nonlinear domain decomposition method and local nonlinear system is solved by Newton methods. Therefore, I have to set up subsnes and also DM for each subsnes.
In PETSc, it provides *DMCreateDomainDecomposition() *for structured grids and then we can have DMs for subsnes. In Libmesh, I found two similar undeclared functions in libmesh/src/solvers/petscdmlibmeshimpl.C, which can help me got DMs for subproblems: *DMCreateFieldDecomposition_libMesh()* and *DMCreateDomainDecomposition_libMesh()* Could you tell me whether two functions work or not? If they work, could you add declarations for them in Libmesh? Could you give me some suggestions to set up subsnes for each subdomain?
