You should only need to ensure that, on the processor which owns the constrained DoF, every dependency of that constrained DoF is present as a ghost DoF. We do that in DoFMap::add_constraints_to_send_list(). That function's currently hard-coded to modify the DoFMap::_send_list based on the DoFMap indexing, but it's short and shouldn't be hard to modify for your alternate ghost vector pattern. --- Roy ------------------------------------------------------------------------------ _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
