Hello all, I have a question regarding use of constraints when using parallel programming.
Suppose I want to constraint dof1 owned by processor 1 to be equal to dof2 owned by processor 2. I can do that by calling ConstraintMatrix constraints; constraints.reinit(locally_relevant_dofs); constraints.add_line(dof1); constraints.add_entry(dof2); Q1. Should it only be called on one processor ? Q2. My question is, what happens when this is called on both the processors (processor 1 and processor 2) ? Q3. What happens when the processor 2 calls the same thing but in the other order ? ConstraintMatrix constraints; constraints.reinit(locally_relevant_dofs); constraints.add_line(*dof2*); constraints.add_entry(*dof1*); If this is wrong, how should the constraint be applied ? -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
