[Libmesh-users] Requirements for adding dof_constraint_rows in parallel

[David K. <dav...@ak...>]

Hi all (though Roy I think you're the expert on this one ;) ),

I know that in DofMap::process_constraints libMesh handles communicating
the constraint rows to the processes that need to know about them, but I
just want to make sure that I satisfy any requirements that we have on how
user-defined constraint rows should be set up in parallel initially.

In particular: are we required to set up the constraint row only on the
process that owns the constrained dof index, or can the constraint row be
on any process (or all processes)?

Thanks,
David
