Member Function Documentation

centerUnitOuterNormal()

template<typename P0 , typename P1 , int I, int O>

GlobalCoordinate Dune::GridGlue::Intersection< P0, P1, I, O >::centerUnitOuterNormal ( ) const

inline

Unit outer normal at the center of the intersection.

The outer normal is given with respect to the geometry().

References Dune::GridGlue::Intersection< P0, P1, I, O >::type(), and Dune::GridGlue::Intersection< P0, P1, I, O >::unitOuterNormal().

geometry()

template<typename P0 , typename P1 , int I, int O>

const Geometry & Dune::GridGlue::Intersection< P0, P1, I, O >::geometry ( ) const

inline

Geometric information about this intersection as part of the inside grid.

This is the same geometry as the application of the first embedding into the "inside" entity and then this entities global geometry.

geometryOutside()

template<typename P0 , typename P1 , int I, int O>

const OutsideGeometry & Dune::GridGlue::Intersection< P0, P1, I, O >::geometryOutside ( ) const

inline

Geometric information about this intersection as part of the outside grid.

This is the same geometry as the application of the first embedding into the "outside" entity and then this entities global geometry.
