Detailed Description

template<int dim, int dimworld, class ct, class GridFamily>
class Dune::GridDefaultImplementation< dim, dimworld, ct, GridFamily >

A Grid is a container of grid entities. Given a dimension dim these entities have a codimension codim with 0 <= codim <= dim.

The Grid is assumed to be hierachically refined and nested. It enables iteration over entities of a given level and codimension.

The grid can be non-matching.

All information is provided to allocate degrees of freedom in appropriate vector data structures (which are not part of this module).

Template class Grid defines a "base class" for all grids.

Member Function Documentation

◆ adapt()

template<int dim, int dimworld, class ct , class GridFamily >

bool Dune::GridDefaultImplementation< dim, dimworld, ct, GridFamily >::adapt ( )

inline

Refine all positive marked leaf entities coarsen all negative marked entities if possible.

Returns: true if a least one entity was refined

Note: this default implementation always returns false so grid with no adaptation doesn't need to implement these methods

◆ communicate() [1/2]

template<int dim, int dimworld, class ct , class GridFamily >

template<class DataHandleImp , class DataTypeImp >

void Dune::GridDefaultImplementation< dim, dimworld, ct, GridFamily >::communicate	(	CommDataHandleIF< DataHandleImp, DataTypeImp > &	data,
		InterfaceType	iftype,
		CommunicationDirection	dir
	)		const

inline

dummy communicate, doing nothing

◆ communicate() [2/2]

template<int dim, int dimworld, class ct , class GridFamily >

template<class DataHandleImp , class DataTypeImp >

void Dune::GridDefaultImplementation< dim, dimworld, ct, GridFamily >::communicate	(	CommDataHandleIF< DataHandleImp, DataTypeImp > &	data,
		InterfaceType	iftype,
		CommunicationDirection	dir,
		int	level
	)		const

inline

dummy communicate, doing nothing

◆ DUNE_DEPRECATED_MSG()

template<int dim, int dimworld, class ct , class GridFamily >

template<class EntitySeed >

Dune::Grid< dim, dimworld, ct, GridFamily >::DUNE_DEPRECATED_MSG ( "entityPointer() is deprecated and will be removed after the release of dune-grid 2.4. Use entity() instead to directly obtain an Entity object." )

inlineinherited

obtain EntityPointer from EntitySeed.

Deprecated:: This method is deprecated and will be removed after the release of dune-grid 2.4. Please use entity() instead, which will directly return an Entity object that you can then store for later use. The EntityPointer concept in general is deprecated and will not be available after dune-grid 2.4 has been released.

obtain Entity from EntitySeed.

◆ getMark() [1/2]

template<int dim, int dimworld, class ct , class GridFamily >

int Dune::Grid< dim, dimworld, ct, GridFamily >::getMark ( const typename Codim< 0 >::Entity & e ) const

inlineinherited

returns adaptation mark for given entity

Parameters

[in] e Entity for which adaptation mark should be determined

Returns: int adaptation mark currently set for given Entity e

References Dune::Grid< dim, dimworld, ct, GridFamily >::asImp().

◆ getMark() [2/2]

template<int dim, int dimworld, class ct , class GridFamily >

int Dune::GridDefaultImplementation< dim, dimworld, ct, GridFamily >::getMark ( const typename Traits::template Codim< 0 >::Entity & e ) const

inline

returns adaptation mark for given entity, i.e. here the default implementation returns 0.

Parameters

[in] e Entity for which adaptation mark should be determined

Returns: int adaptation mark, here the default value 0 is returned

◆ globalRefine()

template<int dim, int dimworld, class ct , class GridFamily >

void Dune::Grid< dim, dimworld, ct, GridFamily >::globalRefine ( int refCount )

inlineinherited

Refine the grid refCount times using the default refinement rule.

This behaves like marking all elements for refinement and then calling preAdapt, adapt and postAdapt. The state after globalRefine is comparable to the state after postAdapt.

References Dune::Grid< dim, dimworld, ct, GridFamily >::asImp(), CHECK_AND_CALL_INTERFACE_IMPLEMENTATION, and Dune::Grid< dim, dimworld, ct, GridFamily >::globalRefine().

Referenced by Dune::Grid< dim, dimworld, ct, GridFamily >::globalRefine().

◆ mark() [1/2]

template<int dim, int dimworld, class ct , class GridFamily >

bool Dune::Grid< dim, dimworld, ct, GridFamily >::mark	(	int	refCount,
		const typename Codim< 0 >::Entity &	e
	)

inlineinherited

Marks an entity to be refined/coarsened in a subsequent adapt.

Parameters

[in]	refCount	Number of subdivisions that should be applied. Negative value means coarsening.
[in]	e	Entity that should be marked

Returns: true if Entity was marked, false otherwise.

References Dune::Grid< dim, dimworld, ct, GridFamily >::asImp().

◆ mark() [2/2]

template<int dim, int dimworld, class ct , class GridFamily >

bool Dune::GridDefaultImplementation< dim, dimworld, ct, GridFamily >::mark	(	int	refCount,
		const typename Traits ::template Codim< 0 >::Entity &	e
	)

inline

Marks an entity to be refined/coarsened in a subsequent adapt.

Parameters

[in]	refCount	Number of subdivisions that should be applied. Negative value means coarsening.
[in]	e	Entity to Entity that should be refined

Returns: true if Entity was marked, false otherwise.

Note

default implementation is: return false; for grids with no adaptation.
for the grid programmer: this method is implemented as a template method, because the Entity type is not defined when the class is instantiated You won't need this trick in the implementation. In your implementation you should use it as
bool mark( int refCount,

typename Traits::template Codim<0>::Entity & e ).

Dune::GridDefaultImplementation::mark
bool mark(int refCount, const typename Traits ::template Codim< 0 >::Entity &e)
Marks an entity to be refined/coarsened in a subsequent adapt.
Definition: grid.hh:1163

Dune::Grid::Codim
A Traits struct that collects all associated types of one implementation.
Definition: grid.hh:438

This template method will vanish due to the inheritance rules.

◆ numBoundarySegments()

template<int dim, int dimworld, class ct , class GridFamily >

size_t Dune::Grid< dim, dimworld, ct, GridFamily >::numBoundarySegments ( ) const

inlineinherited

returns the number of boundary segments within the macro grid

Returns: number of boundary segments within the macro grid
