Detailed Description

One-dimensional adaptive grid.

[ provides Dune::Grid ]

This implementation of the grid interface provides one-dimensional grids only. The OneDGrid can be nonuniform and provides local mesh refinement and coarsening.

Member Typedef Documentation

◆ ctype

typedef double Dune::OneDGrid::ctype

The type used to store coordinates.

If you ever want OneDGrid to use a different type for coordinates, you need to change this type and the third template argument of the base class.

Member Enumeration Documentation

◆ RefinementType

enum Dune::OneDGrid::RefinementType

The different forms of grid refinement supported by OneDGrid.

Enumerator
LOCAL	New level consists only of the refined elements.
COPY	New level consists of the refined elements and the unrefined ones, too.

◆ getMark() [1/3]

int Dune::OneDGrid::getMark ( const Traits::Codim< 0 >::Entity & e ) const

return current adaptation marker of given entity

Parameters

e	Entity to the entity you want to mark

Returns: int current adaptation marker of entity pointer e

◆ getMark() [2/3]

int Dune::Grid< dim, dimworld, double , OneDGridFamily< 1, 1 > >::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

◆ getMark() [3/3]

int Dune::GridDefaultImplementation< dim, dimworld, double , OneDGridFamily< 1, 1 > >::getMark ( const typename Traits::template Codim< 0 >::Entity & e ) const

inlineinherited

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()

void Dune::OneDGrid::globalRefine ( int refCount )

Does one uniform refinement step.

Parameters

refCount I don't know what this is good for. It doesn't actually do anything.

◆ mark() [1/3]

bool Dune::OneDGrid::mark	(	int	refCount,
		const Traits::Codim< 0 >::Entity &	e
	)

Mark entity for refinement.

Parameters

refCount	if >0 mark for refinement, if <0 mark for coarsening
e	Entity to the entity you want to mark

Returns: True, if marking was successfull

◆ mark() [2/3]

bool Dune::Grid< dim, dimworld, double , OneDGridFamily< 1, 1 > >::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.

◆ mark() [3/3]

bool Dune::GridDefaultImplementation< dim, dimworld, double , OneDGridFamily< 1, 1 > >::mark	(	int	refCount,
		const typename Traits ::template 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 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::OneDGrid::mark
bool mark(int refCount, const Traits::Codim< 0 >::Entity &e)
Mark entity for refinement.

This template method will vanish due to the inheritance rules.

◆ maxLevel()

int Dune::OneDGrid::maxLevel ( ) const

inline

Return maximum level defined in this grid.

Levels are numbered 0 ... maxlevel with 0 the coarsest level.

◆ numBoundarySegments()

size_t Dune::OneDGrid::numBoundarySegments ( ) const

inline

Return the number of coarse grid boundary segments.

For this grid implementation, the return value is always 2, because only connected domains are supported, and then the coarse grid boundary consists of two points.
