dealii::MappingQCache and ExaDG::MappingDoFVector are restricted to hypercube elements.

This implies that

  • analytical ALE mesh motions in the IncNS module will not work with simplex meshes
  • FSI with the involved PDE-type ALE mesh motions will not work with simplex meshes
  • biomedical applications currently using our flexible mapping functionality for high-order curved boundaries will not use a consistent mapping in multigrid solvers even for problems without ALE (moving meshes)

The aim of this issue is to discuss/outline how to extend our flexible mapping functionality in ExaDG towards simplex meshes.
