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

◆ boundary()

template<class GridImp >

bool Dune::IdentityGridLeafIntersection< GridImp >::boundary ( ) const

inline

return true if intersection is with boundary.
