struct Dune::Fem::hpDG::DiscontinuousGalerkinBlockMapper< GridPart, LocalKeys >
struct Dune::Fem::hpDG::DiscontinuousGalerkinBlockMapper< GridPart, LocalKeys >
An \(hp\)-adaptive Dune::Fem::DofMapper.
- Template Parameters
-
GridPart a Dune::Fem::GridPart type LocalKeys see documentation below

- The second template parameter is required to provide the following member methods: struct LocalKeys{// type of key// type of datausing DataType = ImplementationDefined;// return maximum number of dofs associated with an entitystd::size_t maxBlocks () const;// return maximum number of dofs for given type and key// map key to data type// map data to key type};Unique label for each type of entities that can occur in DUNE grids.Definition: type.hh:114std::enable_if<(std::is_same< Element, ElementType >::value||std::is_same< Element, GridElementType >::value), constKeyType & >::type key(const Element &element) constget key currently assigned to an entityDefinition: blockmapper.hh:319typename LocalKeysType::KeyType KeyTypekey typeDefinition: blockmapper.hh:120Dummy struct used for documentation purposes.Definition: documentation.hh:42
Member Function Documentation
◆ contains()
|
inlineinherited |
returns true if DoFs for given codimension exist
- Parameters
-
[in] codim codimension to check
- Returns
- true if DoFs for codimension exist
◆ mapEach()
|
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()
|
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.
◆ update()
|
inlineinherited |
update DoF mapping after grid modification
Adaptive DoF mappers are considered to be always up to date and this method does nothing.
