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

template<class GridImp >

bool Dune::IdentityGridLeafIntersection< GridImp >::boundary

(

)

const [inline]

return true if intersection is with boundary.

template<class GridImp >

int Dune::IdentityGridLeafIntersection< GridImp >::boundaryId

(

)

const [inline]

return information about the Boundary

template<class GridImp >

size_t Dune::IdentityGridLeafIntersection< GridImp >::boundarySegmentIndex

(

)

const [inline]

return the boundary segment index

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.

template<class GridImp >

bool Dune::IdentityGridLeafIntersection< GridImp >::conforming

(

)

const [inline]

Return true if this is a conforming intersection.

template<class GridImp >

const 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.

template<class GridImp >

const 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.

template<class GridImp >

const LocalGeometry& Dune::IdentityGridLeafIntersection< GridImp >::geometryInOutside

(

template<class GridImp >

EntityPointer Dune::IdentityGridLeafIntersection< GridImp >::inside

(

)

const [inline]
