Are you sure? Before the distributed::Triangulation existed, you would use DoFRenumbering::subdomain_wise (dof_handler); DoFTools::count_dofs_with_subdomain_association() etc, like in step-17 or not? > However, these functions seemed to have changed > drastically.

I think we could generate these IndexSets for a non-distributed::Triangulation by looking at the subdomain. Would that be a good idea? (I never liked the fact, that the ownership was only implicitly defined and returned by the DoFTools::count_dofs_with_subdomain_association() which is rather hard to find) -- Timo Heister http://www.math.tamu.edu/~heister/ _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
