Detailed Description

Requirements for implementations of the Dune::Grid interface.

The Grid concept defines interface requirements of a parallel, in general nonconforming, locally refined and hierarchical finite element mesh. It consists of sub-concepts for Dune::Concept::GridView, Dune::Concept::IndexSet, Dune::Concept::IdSet, and Dune::Concept::Intersection.

See Dune::Grid for an "abstract" interface definition of this concept.
