-       * in p4est happens. This can be a bit more expensive, but guarantees
-       * the same memory layout and therefore cell ordering in the deal.II
-       * mesh. As assembly is done in the deal.II cell ordering, this flag is
-       * required to get reproducible behaviour after snapshot/resume.
-       *
-       * The flag construct_multigrid_hierarchy needs to be set to use the
-       * geometric multigrid functionality. This option requires additional
-       * computation and communication. Note: geometric multigrid is still a
-       * work in progress.
-       *
-       * @p no_automatic_repartitioning will disable automatic repartioning of
-       * the cells after a refinement cycle. It can be executed manually by
-       * calling repartition().
