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!

Constructor & Destructor Documentation

◆ ALU3dGridIntersectionIterator()

template<class GridImp >
Dune::ALU3dGridIntersectionIterator< GridImp >::ALU3dGridIntersectionIterator ( const FactoryType &  factory,
HElementType *  el,
int  wLevel,
bool  end = false 
)

The default Constructor , level tells on which level we want neighbours

Member Function Documentation

◆ 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 ( ) const

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

◆ integrationOuterNormal()

template<class GridImp >
NormalType & Dune::ALU3dGridIntersectionIterator< GridImp >::integrationOuterNormal ( const FieldVector< alu3d_ctype, dim-1 > &  local) const

return outer normal, this should be dependent on local coordinates for higher order boundary

◆ outerNormal()

template<class GridImp >
NormalType & Dune::ALU3dGridIntersectionIterator< GridImp >::outerNormal ( const FieldVector< alu3d_ctype, dim-1 > &  local) const

return outer normal, this should be dependent on local coordinates for higher order boundary

◆ unitOuterNormal()

template<class GridImp >
NormalType & Dune::ALU3dGridIntersectionIterator< GridImp >::unitOuterNormal ( const FieldVector< alu3d_ctype, dim-1 > &  local) const

return unit outer normal, this should be dependent on local coordinates for higher order boundary

Member Data Documentation

◆ connector_

template<class GridImp >
FaceInfoType Dune::ALU3dGridIntersectionIterator< GridImp >::connector_
mutableprotected

structure containing the topological and geometrical information about the face which the iterator points to
