Detailed Description

template<int dim, int dimworld, ALU2DSPACE ElementType eltype>
class Dune::ALU2dGrid< dim, dimworld, eltype >

[ provides Dune::Grid ]

2D grid, will provide non conform grids The ALU2dGrid implements the Dune GridInterface for 2d meshes. This grid can be locally adapted and will provide non conform grids.

Note: Adaptive grid, written mainly by Bernard Schupp. This grid supports non conform grids.

◆ mark() [1/3]

bool Dune::Grid< dim, dimworld, alu2d_ctype , ALU2dGridFamily< dim, dimworld, eltype > >::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() [2/3]

bool Dune::GridDefaultImplementation< dim, dimworld, alu2d_ctype , ALU2dGridFamily< dim, dimworld, eltype > >::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::ALU2dGrid::mark
bool mark(int refCount, const typename Traits::template Codim< 0 >::Entity &e)
Marks an entity to be refined/coarsened in a subsequent adapt.

This template method will vanish due to the inheritance rules.

◆ mark() [3/3]

template<int dim, int dimworld, ALU2DSPACE ElementType eltype>

bool Dune::ALU2dGrid< dim, dimworld, eltype >::mark	(	int	refCount,
		const typename Traits::template Codim< 0 >::Entity &	e
	)

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.

◆ maxLevel()

template<int dim, int dimworld, ALU2DSPACE ElementType eltype>

int Dune::ALU2dGrid< dim, dimworld, eltype >::maxLevel ( ) const

Return maximum level defined in this grid. Levels are numbered 0 ... maxLevel with 0 the coarsest level.

◆ nonConform()

template<int dim, int dimworld, ALU2DSPACE ElementType eltype>

bool Dune::ALU2dGrid< dim, dimworld, eltype >::nonConform ( ) const

inlineprotected

return true if grid allows hanging nodes on leaf level i.e. returns true for ALUSimplexGrid and returns false for ALUConformGrid

Referenced by Dune::ALU2dGrid< dim, dimworld, eltype >::conformingRefinement().
