For Hypercube elements, this should actually work.

For Simplex elements, this is not available in deal.II currently.

It seems that with the current solution in deal.II, we would need to change the interfaces in ExaDG, which requires a lot of changes. So I think for now I would add an assert to ExaDG, stating that one should use parallel::distributed::Triangulation in case of periodic boundaries.

@petterum could you provide the link to the respective test (periodic BCs with fullydistributed) in deal.II?
