Detailed Description

template<class GridImp>
class Dune::ALU3dGridIntersectionIterator< GridImp >

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

geometry()

template<class GridImp >

Geometry Dune::ALU3dGridIntersectionIterator< 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::ALU3dGridIntersectionIterator< 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::ALU3dGridIntersectionIterator< GridImp >::geometryInOutside

(

)

const

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

indexInInside()

template<class GridImp >

int Dune::ALU3dGridIntersectionIterator< GridImp >::indexInInside

(

)

const

local index of codim 1 entity in self where intersection is contained in

indexInOutside()

template<class GridImp >

int Dune::ALU3dGridIntersectionIterator< GridImp >::indexInOutside
