Detailed Description

Iterator over all element neighbors

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 These neighbors are accessed via a IntersectionIterator. This allows the implement non-matching meshes. The number of neighbors may be different from the number of an element!

geometry()

template<class GridImp >

Geometry Dune::FoamGridLeafIntersection< GridImp >::geometry ( ) const

inline

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::FoamGridLeafIntersection< GridImp >::geometryInInside ( ) const

inline

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::FoamGridLeafIntersection< GridImp >::geometryInOutside ( std::size_t  neighborIndex = 0 ) const

inline

intersection of codimension 1 of this neighbor with element where iteration started. Here returned element is in LOCAL coordinates of neighbor In the LeafIntersection the intersection might be non-conforming For surface grids with local non-conforming adaptivity the geometryInOutside is undefined

inside()

template<class GridImp >

Entity Dune::FoamGridIntersection< GridImp >::inside ( ) const

inlineinherited

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

outside()

template<class GridImp >

Entity Dune::FoamGridIntersection< GridImp >::outside ( ) const

inlineinherited

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