Detailed Description

template<int dim, class GridImp>
class Dune::ALU2dGridEntity< 0, dim, GridImp >

A Grid is a container of grid entities. An entity is parametrized by the codimension. An entity of codimension c in dimension d is a d-c dimensional object.

Entities of codimension 0 ("elements") are defined through template specialization. Note that this specialization has an extended interface compared to the general case

Entities of codimension 0 allow to visit all neighbors, where a neighbor is an entity of codimension 0 which has a common entity of codimension 1 with the These neighbors are accessed via an iterator. This allows the implementation of non-matching meshes. The number of neigbors may be different from the number of faces/edges of an element!

Member Function Documentation

template<int dim, class GridImp >
int Dune::ALU2dGridEntity< 0, dim, GridImp >::boundaryId ( ) const
inline

Id of the boundary which is associated with the entity, returns 0 for inner entities, arbitrary int otherwise.

template<int dim, class GridImp >
template<int cc>
int Dune::ALU2dGridEntity< 0, dim, GridImp >::count ( ) const
inline

Intra-element access to entities of codimension cc > codim. Return number of entities with codimension cc.

template<int dim, class GridImp >
template<int cc>
Codim<cc>::EntityPointer Dune::ALU2dGridEntity< 0, dim, GridImp >::entity ( int  i) const

Provide access to mesh entity i of given codimension. Entities are numbered 0 ... count<cc>()-1

template<int dim, class GridImp >
bool Dune::ALU2dGridEntity< 0, dim, GridImp >::equals ( const ALU2dGridEntity< 0, dim, GridImp > &  org) const

compare 2 entities, which means compare the item pointers

template<int dim, class GridImp >

inline

return reference to factory

template<int dim, class GridImp >
EntityPointer Dune::ALU2dGridEntity< 0, dim, GridImp >::father ( ) const

Inter-level access to father element on coarser grid. Assumes that meshes are nested.

template<int dim, class GridImp >
Geometry Dune::ALU2dGridEntity< 0, dim, GridImp >::geometry ( ) const

geometry of this entity

template<int dim, class GridImp >
LocalGeometry Dune::ALU2dGridEntity< 0, dim, GridImp >::geometryInFather ( ) const

Location of this element relative to the reference element of the father. This is sufficient to interpolate all dofs in conforming case. Nonconforming may require access to neighbors of father and computations with local coordinates. On the fly case is somewhat inefficient since dofs are visited several times. If we store interpolation matrices, this is tolerable. We assume that on-the-fly implementation of numerical algorithms is only done for simple discretizations. Assumes that meshes are nested.

template<int dim, class GridImp >
ALU2dGridHierarchicIterator<GridImp> Dune::ALU2dGridEntity< 0, dim, GridImp >::hbegin ( int  maxLevel) const

References Dune::ALU2dGridEntity< cd, dim, GridImp >::factory().

template<int dim, class GridImp >
ALU2dGridIntersectionIteratorType Dune::ALU2dGridEntity< 0, dim, GridImp >::ibegin ( ) const
inline

Intra-level access to intersection with neighboring elements. A neighbor is an entity of codimension 0 which has an entity of codimension 1 in commen with this entity. Access to neighbors is provided using iterators. This allows meshes to be nonmatching. Returns iterator referencing the first neighbor.
