I am having an error when running more than 1 core (with MPI) in a similar
implementation to step-40 when using a component wise ordering:
DoFRenumbering::component_wise(dof_handler) in the setup_syste() function.
Is ii possible to do what I am trying to do?
Yes, but then you also have to use block vectors and matrices. (You could also
use parallel::distributed::Vector or TrilinosWrappers::Vector, just not
PETScWrappers::Vector.) In general, if you want to renumber component wise,
then it's because you want to block vectors and matrices based on the physical
components of the solution vector.
