Beyond all the other questions that have been raised on this list, let me ask what constraints you have at all? If you use discontinuous elements, there shouldn't be any and in that case the distribute_local_to_global function does a straight copy of the local matrix and vector entries into the global objects in the same way as, for example, steps 3...6. You won't need the constraints object for anything at all in that case. Best W. _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
