This makes the class completely +equivalent to the previous class MappingQGeneric. All functionality in the +latter class has been integrated into the MappingQ class. This avoids errors +with curved manifolds in the interior of the domain, where MappingQ could lead +to gaps or overlaps in the computational domain. In case the slightly better +performance of using MappingQ1 in interior cells is desired, +hp::MappingCollection can be used to replicate the old behavior. +
