Thank you for your answer. I am trying to substitute my PETScWrappers::MPI::Vector for parallel::distributed::Vector (locally_relevant_solution and system_rhs) but my lac library does not contain the filee
*deal.II/lac/parallel_vector.h. *I even tried to get the latest version but is not there. Where can I find it?
