bool	hasFather () const
	Return true if this element has a father element.
Entity	father () const
LocalGeometry	geometryInFather () const
	Location of this element relative to the reference element 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.
FoamGridHierarchicIterator< GridImp >	hbegin (int maxLevel) const
	Inter-level access to son elements on higher levels<=maxlevel. This is provided for sparsely stored nested unstructured meshes. Returns iterator to first son.

	Returns iterator to one past the last son.
void	setToTarget (const FoamGridEntityImp< dimgrid, dimgrid, dimworld, ctype > *target)
	Make this class point to a new FoamGridEntityImp object.
bool	equals (const Dune::FoamGridEntity< 0, dimgrid, GridImp > &other) const
	equality
GeometryType	type () const
	return the entity's type

Detailed Description

template<class GridImp>
class Dune::FoamGridEntity< 0, 2, GridImp >

Specialization for codim-0-entities, i.e., elements for dimgrid==2.

This class embodies the topological parts of elements of the grid. It has an extended interface compared to the general entity class. For example, Entities of codimension 0 allow to visit all neighbors.

father()

template<class GridImp >

Entity Dune::FoamGridEntity< 0, 2, GridImp >::father ( ) const

inline

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

operator=()

template<class GridImp >

FoamGridEntity & Dune::FoamGridEntity< 0, 2, GridImp >::operator= ( const FoamGridEntity< 0, 2, GridImp > &  original )

inline

subEntities()

template<class GridImp >

unsigned int Dune::FoamGridEntity< 0, 2, GridImp >::subEntities ( unsigned int  codim ) const

inline

Return number of subentities with codimension cc.

That number is (dim over (dim-codim)) times 2^codim
