Detailed Description

template<int dim, class Coordinates = EquidistantCoordinates<double, dim>>
class Dune::YaspGrid< dim, Coordinates >

[ provides Dune::Grid ]

Provides a distributed structured cube mesh.

YaspGrid stands for yet another structured parallel grid. It implements the dune grid interface for structured grids with arbitrary overlap (including zero), periodic boundaries, and a fast implementation allowing on-the-fly computations.

YaspGrid supports three coordinate modes: EquidistantCoordinates, EquidistantOffsetCoordinates, and Dune::TensorProductCoordinates.

Template Parameters

dim	The dimension of the grid and its surrounding world
Coordinates	The coordinate mode of the grid.

Examples

recipe-integration.cc, and recipe-iterate-over-grid.cc.

mark() [1/3]

bool Dune::Grid< dim, dimworld, Coordinates::ctype , YaspGridFamily< dim, EquidistantCoordinates< double, dim > > >::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, Coordinates::ctype , YaspGridFamily< dim, EquidistantCoordinates< double, dim > > >::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 ).

  This template method will vanish due to the inheritance rules.

mark() [3/3]

template<int dim, class Coordinates = EquidistantCoordinates<double, dim>>

bool Dune::YaspGrid< dim, Coordinates >::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

• On yaspgrid marking one element will mark all other elements of the level as well
• If refCount is lower than refCount of a previous mark-call, nothing is changed
