Detailed Description

template<class GridImp>
class Dune::MMeshLeafIntersection< 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::MMeshLeafIntersection< 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.

References Dune::MMeshLeafIntersection< GridImp >::unitOuterNormal().

geometry()

template<class GridImp >

Geometry Dune::MMeshLeafIntersection< 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::MMeshLeafIntersection< 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.

References Dune::MMeshLeafIntersection< GridImp >::indexInInside().

geometryInOutside()

template<class GridImp >

LocalGeometry Dune::MMeshLeafIntersection< 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

References Dune::MMeshLeafIntersection< GridImp >::indexInOutside(), and Dune::MMeshLeafIntersection< GridImp >::neighbor().

inside()

template<class GridImp >

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

inline

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

References Dune::MMeshLeafIntersection< GridImp >::neighbor().
