Detailed Description

template<class DofMapperTraits>
class Dune::Fem::AdaptiveDofMapper< DofMapperTraits >

Extended interface for adaptive DoF mappers.

Member Function Documentation

contains()

template<class DofMapperTraits >

bool Dune::Fem::DofMapper< DofMapperTraits >::contains ( const int  codim ) const

inlineinherited

returns true if DoFs for given codimension exist

Parameters

[in]

codim

codimension to check

Returns

true if DoFs for codimension exist

mapEach()

template<class DofMapperTraits >

template<class Functor >

void Dune::Fem::DofMapper< DofMapperTraits >::mapEach ( const ElementType &  element, Functor  f  ) const

inlineinherited

map each local DoF number to a global key

Parameters

[in]	element	element, the DoFs belong to
[in]	f	functor to call for each DoF

The functor has to be a copyable object satisfying the following interface:

struct Functor
{
 
  // application operator
  template< class GlobalKey >
  void operator() ( const int localDoF, const GlobalKey &globalDoF );
};

For each DoF to be mapped, this method will call the application operator once.

Note

There is no guarantee on the order, in which the functor is applied.

The global key has to be compatible with the Dof storage.

mapEachEntityDof()

template<class DofMapperTraits >

template<class Entity , class Functor >

void Dune::Fem::DofMapper< DofMapperTraits >::mapEachEntityDof ( const Entity &  entity, Functor  f  ) const

inlineinherited

map each local DoF number to a global key

Parameters

[in]	entity	entity, the DoFs belong to
[in]	f	functor to call for each DoF

The functor has to be a copyable object satisfying the following interface:

struct Functor
{
 
  // application operator
  template< class GlobalKey >
  void operator() ( const int localDoF, const GlobalKey &globalKey );
};

For each DoF to be mapped, this method will call the application operator once.

Note

There is no guarantee on the order, in which the functor is applied.

The global key has to be compatible with the Dof storage.

numDofs()

template<class DofMapperTraits >

SizeType Dune::Fem::DofMapper< DofMapperTraits >::numDofs ( const ElementType &  element ) const

inlineinherited

obtain number of DoFs on an entity

Parameters

[in]

element

entity of codimension 0

Returns

number of DoFs on the entity

numEntityDofs()

template<class DofMapperTraits >

template<class Entity >

SizeType Dune::Fem::DofMapper< DofMapperTraits >::numEntityDofs ( const Entity &  entity ) const

inlineinherited

obtain number of DoFs actually belonging to an entity

In contrast to numDofs, this method returns the number of DoFs actually associated with an entity (usually a subentity). We have the following relation for an entity \(E\) of codimension 0:

\[ \mathrm{numDofs}( E ) = \sum_{e \subset E} \mathrm{numEntityDofs}( e ), \]

where \(\subset\) denotes the subentity relation.

Parameters

[in]

entity

entity of codimension

Returns

number of DoFs on the entity

update()

template<class DofMapperTraits >

void Dune::Fem::AdaptiveDofMapper< DofMapperTraits >::update ( )

inline

update DoF mapping after grid modification

Adaptive DoF mappers are considered to be always up to date and this method does nothing.
