Detailed Description

template<class GridImp>
class Dune::SIntersectionIterator< GridImp >

Mesh entities of codimension 0 ("elements") allow to visit all neighbors, where a neighbor is an entity of codimension 0 which has a common entity of codimension 1 with the entity. These neighbors are accessed via a IntersectionIterator. This allows the implementation of non-matching meshes. The number of neigbors may be different from the number of faces/edges of an element!

Member Function Documentation

geometry()

template<class GridImp >

Geometry Dune::SIntersectionIterator< GridImp >::geometry

(

)

const

intersection of codimension 1 of this neighbor with element where iteration started. Here returned element is in GLOBAL coordinates of the element where iteration started.

geometryInInside()

template<class GridImp >

LocalGeometry Dune::SIntersectionIterator< GridImp >::geometryInInside

(

)

const

intersection of codimension 1 of this neighbor with element where iteration started. Here returned element is in LOCAL coordinates of the element where iteration started.

geometryInOutside()

template<class GridImp >

LocalGeometry Dune::SIntersectionIterator< GridImp >::geometryInOutside

(

)

const

intersection of codimension 1 of this neighbor with element where iteration started. Here returned element is in LOCAL coordinates of neighbor

inside()

template<class GridImp >

EntityPointer Dune::SIntersectionIterator< GridImp >::inside

(

)

const

return EntityPointer to the Entity on the inside of this intersection (that is the Entity where we started this Iterator)

outside()

template<class GridImp >

EntityPointer Dune::SIntersectionIterator< GridImp >::outside

(

)

const

return EntityPointer to the Entity on the outside of this intersection (that is the neighboring Entity)
