Detailed Description

template<class ct, int dim>
class Dune::EquidistantOffsetCoordinates< ct, dim >

Container for equidistant coordinates in a YaspGrid with non-trivial origin.

Template Parameters

ct	the coordinate type
dim	the dimension of the grid

Constructor & Destructor Documentation

EquidistantOffsetCoordinates()

template<class ct , int dim>

Dune::EquidistantOffsetCoordinates< ct, dim >::EquidistantOffsetCoordinates ( const Dune::FieldVector< ct, dim > &  origin, const Dune::FieldVector< ct, dim > &  h, const std::array< int, dim > &  s  )

inline

construct a container with all necessary information

Parameters

h	the meshsize in all directions
s	the size (in codim 0 elements) of the grid on this processor
origin	the coordinate of the lowerleft corner of this grid the size information is kept with this container, because this is the natural way to handle this for a tensorproduct grid.

Member Function Documentation

coordinate()

template<class ct , int dim>

ct Dune::EquidistantOffsetCoordinates< ct, dim >::coordinate ( int  d, int  i  ) const

inline

Returns

a coordinate given a direction and an index

Parameters

d	the direction to be used
i	the global coordinate index

meshsize()

template<class ct , int dim>

ct Dune::EquidistantOffsetCoordinates< ct, dim >::meshsize ( int  d, int  i  ) const

inline

Returns

the meshsize in given direction at given position

Parameters

d	the direction to be used
i	the global coordinate index where to return the meshsize

origin()

template<class ct , int dim>

ct Dune::EquidistantOffsetCoordinates< ct, dim >::origin ( int  d ) const

inline

Returns

the dth component of the origin

Parameters

d	the direction to be used

refine()

template<class ct , int dim>

EquidistantOffsetCoordinates<ct,dim> Dune::EquidistantOffsetCoordinates< ct, dim >::refine ( std::bitset< dim >  ovlp_low, std::bitset< dim >  ovlp_up, int  overlap, bool  keep_ovlp  ) const

inline

Returns

a container that represents the same grid after one step of uniform refinement

Parameters

ovlp_low	whether we have an overlap area at the lower processor boundary
ovlp_up	whether we have an overlap area at the upper processor boundary
overlap	the size of the overlap region
keep_ovlp	the refinement option parameter to be used

size()

template<class ct , int dim>

int Dune::EquidistantOffsetCoordinates< ct, dim >::size ( int  d ) const

inline

Returns

the size in given direction

Parameters

d	the direction to be used
