Constructor & Destructor Documentation

Geometry()

template<int cdim>

Dune::cpgrid::Geometry< 2, cdim >::Geometry ( const GlobalCoordinate & pos, ctype vol )

inline

Construct from centroid and volume (1- and 0-moments).

Parameters

pos	the centroid of the entity
vol	the volume(area) of the entity

Member Function Documentation

corners()

template<int cdim>

int Dune::cpgrid::Geometry< 2, cdim >::corners ( ) const

inline

The number of corners of this convex polytope.

Since this geometry is singular, we have no corners as such.
