Detailed Description

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

geometry implementation for AlbertaGrid

Defines the geometry part of a mesh entity. Works for all dimensions, element types and dim of world. Provides reference element and mapping between local and global coordinates.

Template Parameters

mydim	dimension of the element (0 <= dim <= 3)
cdim	dimension of global coordinates
GridImp	grid implementation (always const AlbertaGrid< dim, dimworld >)
