Detailed Description

template<typename GV>
class Dune::MultipleCodimMultipleGeomTypeMapper< GV >

Implementation class for a multiple codim and multiple geometry type mapper.

In this implementation of a mapper the entity set used as domain for the map consists of the entities of a subset of codimensions in the given index set. The index set may contain entities of several geometry types.

The geometry types to be included in the mapper are selected using a layout functional (MCMGLayout) that is passed to the constructor.

Member Typedef Documentation

◆ size_type

template<typename GV >

using Dune::MultipleCodimMultipleGeomTypeMapper< GV >::size_type = decltype(std::declval<typename GV::IndexSet>().size(0))

Number type used for the overall size (the return value of the 'size' method)

The type used here is set to be the corresponding type used by the GridView's index set.

◆ MultipleCodimMultipleGeomTypeMapper()

template<typename GV >

Dune::MultipleCodimMultipleGeomTypeMapper< GV >::MultipleCodimMultipleGeomTypeMapper	(	const GV &	gridView,
		const MCMGLayout &	layout
	)

inline

construct mapper from grid and layout description

The layout parameter is a functional describing entities of which geometry types are included in the mapper. For commonly used cases, convenience functions are provided. See the MCMGLayout type documentation for details.

Parameters

gridView	grid view whose entities should be included in the mapper
layout	functional describing how many dof to store on each entity (fixed per geometry type)

◆ index()

template<typename GV >

template<class EntityType >

Index Dune::MultipleCodimMultipleGeomTypeMapper< GV >::index ( const EntityType & e ) const

inline

Map entity to starting index in array for dof block.

◆ indices() [1/2]

template<typename GV >

template<class EntityType >

IntegralRange< Index > Dune::MultipleCodimMultipleGeomTypeMapper< GV >::indices ( const EntityType & e ) const

inline

Returns a pair with the starting point in the dof vector and the number of degrees of freedom if the entity is contained in the index set otherwise {0,0} is returned.

Parameters

e	Reference to entity
result	integer reference to the start of the block

Returns: pair with first entry equal to index for that entity and the second entry the number of degrees of freedom (zero if entity is not in entity set of the mapper)

IntegralRange< Index > Dune::MultipleCodimMultipleGeomTypeMapper< GV >::indices	(	const typename GV::template Codim< 0 >::Entity &	e,
		int	i,
		int	cc
	)		const

inline

Returns a pair with the starting point in the dof vector and the number of degrees of freedom if the entity is contained in the index set otherwise {0,0} is returned.

Parameters

e	Reference to codim 0 entity
i	subentity number
cc	subentity codim
result	integer reference to the start of the block

Returns: pair with first entry equal to index for that entity and the second entry the number of degrees of freedom (zero if sub entity is not in entity set of the mapper)

◆ size()

template<typename GV >

size_type Dune::MultipleCodimMultipleGeomTypeMapper< GV >::size ( ) const

inline

Return total number of entities in the entity set managed by the mapper.

This number can be used to allocate a vector of data elements associated with the entities of the set. In the parallel case this number is per process (i.e. it may be different in different processes).

Returns: Size of the entity set.

◆ subIndex() [1/2]

Index Dune::Mapper< GV::Grid , MultipleCodimMultipleGeomTypeMapper< GV > , GV::IndexSet::IndexType >::subIndex	(	const typename G::Traits::template Codim< 0 >::Entity &	e,

Parameters

e	Reference to codim 0 entity.
i	Number of codim cc subentity of e, where cc is the template parameter of the function.
codim	codimension of subentity of e

◆ update() [1/2]

template<typename GV >

void Dune::MultipleCodimMultipleGeomTypeMapper< GV >::update ( const GV & gridView )

inline

Recalculates indices after grid adaptation.

After grid adaptation you need to call this to update the stored gridview and recalculate the indices.
