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.

Communicate information on distributed entities on a given level Template parameter is a model of Dune::CommDataHandleIF.

Parameters
dataA data handle telling the method what data is communicated and how this should be done.
interfaceThe communication interface to use.
dirThe direction of the communication along the interface (forward or backward.
levelThe index of the grid level where the communication should happen.

◆ DUNE_DEPRECATED_MSG()

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.

◆ 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]refCountNumber of subdivisions that should be applied. Negative value means coarsening.
[in]eEntity 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]refCountNumber of subdivisions that should be applied. Negative value means coarsening.
[in]eEntity 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 ).
    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]refCountNumber of subdivisions that should be applied. Negative value means coarsening.
[in]eEntity 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().
