Detailed Description

template<int mydim, int cdim, class GridImp>
class Dune::YaspGeometry< mydim, cdim, GridImp >

The general version implements dim==dimworld-1. If this is not the case an error is thrown.

YaspGeometry realizes the concept of the geometric part of a mesh entity.

We have specializations for dim == dimworld (elements) and dim == 0 (vertices). The general version implements dim == dimworld-1 (faces) and otherwise throws a GridError.
