Dune::IdentityGridLeafIntersection< GridImp > Class Template Reference

An intersection with a leaf neighbor elementMesh 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! More...

Detailed Description

template<class GridImp>
class Dune::IdentityGridLeafIntersection< GridImp >

An intersection with a leaf neighbor element

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!

Member Function Documentation

◆ centerUnitOuterNormal()

template<class GridImp >
NormalVector Dune::IdentityGridLeafIntersection< GridImp >::centerUnitOuterNormal ( ) const
inline

Return unit outer normal (length == 1)

The returned vector is the normal at the center() of the intersection's geometry. It is scaled to have unit length.

◆ geometry()

template<class GridImp >
Geometry Dune::IdentityGridLeafIntersection< 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::IdentityGridLeafIntersection< 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::IdentityGridLeafIntersection< GridImp >::geometryInOutside ( ) const
inline

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 >
Entity Dune::IdentityGridLeafIntersection< GridImp >::inside ( ) const
inline

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

◆ outside()

template<class GridImp >
Entity Dune::IdentityGridLeafIntersection< GridImp >::outside ( ) const
inline

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