Seyed, your results look like the ghost values are wrong. My first guess would be that you are still using a completely distributed vector (one initialized with locally_owned_dofs only) instead of a ghosted one (initialized with locally_owned_dofs and locally_relevant_dofs). Can you confirm that after solving you do something like
configurational_forces = local_configurational_forces; and that configurational_forces.has_ghost_values() == true local_configurational_forces.has_ghost_values() == false holds? Can you confirm that you use configurational_forces and not local_configurational_forces for output? What is the output of configurational_forces.print(std::cout)? What kind of error do you get when trying with pcout instead of std::cout? > Maybe this helps: > > How do you compute "reaction forces" within deal.II? > What exactly do you mean by that? We are much better if you can provide us with formulas rather than application-specific names. >From my understanding, you mean a projection, isn't it? So solving for u such that (u,v)=(f,v) for all v and given f? This is implemented in the VectorTools::project functions.[1] Best, Daniel [1] https://www.dealii.org/developer/doxygen/deal.II/namespaceVectorTools.html -- 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.
