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
ctthe coordinate type
dimthe 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
hthe meshsize in all directions
sthe size (in codim 0 elements) of the grid on this processor
originthe 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
dthe direction to be used
ithe 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
dthe direction to be used
ithe 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
dthe 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_lowwhether we have an overlap area at the lower processor boundary
ovlp_upwhether we have an overlap area at the upper processor boundary
overlapthe size of the overlap region
keep_ovlpthe 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
dthe direction to be used
