Member Function Documentation

centerUnitOuterNormal()

template<typename I >

Dune::FieldVector< ctype, coorddimension > Dune::PDELab::IntersectionGeometry< I >::centerUnitOuterNormal ( ) const

inline

Return unit outer normal (length == 1)

The returned vector may depend on the local position within the intersection. It is scaled to have unit length.

geometry()

template<typename I >

Geometry Dune::PDELab::IntersectionGeometry< I >::geometry ( ) const

inline

geometrical information about this intersection in global coordinates.

This method returns a Geometry object that provides a mapping from local coordinates of the intersection to global (world) coordinates.

geometryInInside()

template<typename I >

LocalGeometry Dune::PDELab::IntersectionGeometry< I >::geometryInInside ( ) const

inline

geometrical information about this intersection in local coordinates of the inside() entity.

This method returns a Geometry object that provides a mapping from local coordinates of the intersection to local coordinates of the inside() entity.

geometryInOutside()

template<typename I >

LocalGeometry Dune::PDELab::IntersectionGeometry< I >::geometryInOutside ( ) const

inline

geometrical information about this intersection in local coordinates of the outside() entity.

This method returns a Geometry object that provides a mapping from local coordinates of the intersection to local coordinates of the outside() entity.

insideDomainIndex()

template<typename I >

int Dune::PDELab::IntersectionGeometry< I >::insideDomainIndex ( ) const

inline

integrationOuterNormal()

template<typename I >

Dune::FieldVector< ctype, coorddimension > Dune::PDELab::IntersectionGeometry< I >::integrationOuterNormal ( const Dune::FieldVector< ctype, mydimension > &  local ) const

inline

return outer normal scaled with the integration element

Return an outer normal (length not necessarily 1)

The returned vector may depend on local position within the intersection. The normal is scaled with the integration element of the intersection. This method is redundant but it may be more efficent to use this function rather than computing the integration element via intersectionGlobal().

intersection()

template<typename I >

const I & Dune::PDELab::IntersectionGeometry< I >::intersection ( ) const

inline

outerNormal()

template<typename I >

Dune::FieldVector< ctype, coorddimension > Dune::PDELab::IntersectionGeometry< I >::outerNormal ( const Dune::FieldVector< ctype, mydimension > &  local ) const

inline

Return an outer normal (length not necessarily 1)

The returned vector may depend on local position within the intersection.

outside()

template<typename I >

Entity Dune::PDELab::IntersectionGeometry< I >::outside ( ) const

inline

return Entity on the outside of this intersection. That is the neighboring Entity.

Warning

Don't call this method if there is no neighboring Entity (neighbor() returns false). In this case the result is undefined.

outsideDomainIndex()

template<typename I >

int Dune::PDELab::IntersectionGeometry< I >::outsideDomainIndex ( ) const

inline

unitOuterNormal()

template<typename I >

Dune::FieldVector< ctype, coorddimension > Dune::PDELab::IntersectionGeometry< I >::unitOuterNormal ( const Dune::FieldVector< ctype, mydimension > &  local ) const

inline

Return unit outer normal (length == 1)

The returned vector may depend on the local position within the intersection. It is scaled to have unit length.
