Hi All,
I have a question about resolving chains of constraints in a ConstraintMatrix class object after calling close() in a parallel distributed case: I created a ConstraintMatrix with both periodic and hanging node constraints, and called close(). Then I picked a constrained degree of freedom, lets say with global dof id = “i” and printed the constraint equation pairs (j,a_ij) corresponding to “i” on the processor for which “i” is locally owned as well as the processors for which “i” is a ghost. I expected the constraint equation to be the same for owning processor and the ghost processor, however we have encountered a case where printing the constraint equation entries shows different “j” for owning and ghost processorsalthough a_ij are same. When we printed the coordinates of “j” which were different, we found that those two nodes to be periodic images of each other. Should I except the constraint equation to be the same for the owning processor and the ghost processors?
