Detailed Description

template<int dim>
class Dune::SPTopology< dim >

description of the grid's topology

The topology of a Cartesian grid is a set of cubes (called nodes, here) and their connectivity.

Note

Currently, only 1 node is supported.

Template Parameters

dim	dimension of the grid

Constructor & Destructor Documentation

SPTopology()

template<int dim>

Dune::SPTopology< dim >::SPTopology ( const unsigned int  periodic = 0 )

inlineexplicit

constructor

Parameters

[in]

periodic

bit field specifying which directions should be periodic (defaults to 0)

Member Function Documentation

hasNeighbor()

template<int dim>

bool Dune::SPTopology< dim >::hasNeighbor ( const unsigned int  node, const int  face  ) const

inline

check whether a node has a neighbor over a face

Parameters

[in]	node	index of the node
[in]	face	number of the face

Returns

true, if there is a neighbor

neighbor()

template<int dim>

unsigned int Dune::SPTopology< dim >::neighbor ( const unsigned int  node, const int  face  ) const

inline

obtain neighbor of a node over a face

Parameters

[in]	node	index of the node
[in]	face	number of the face

Note

The neighboring node will have the given node as neighbor over the opposite face.

Returns

the index of the neighboring node

periodic() [1/2]

template<int dim>

unsigned int Dune::SPTopology< dim >::periodic

inline

obtain the periodicity bit field

Note

This method only makes sense in case of a single node

Returns

the bitfield specifying which directions are periodic

References Dune::Functions::BasisFactory::Experimental::periodic().

periodic() [2/2]

template<int dim>

bool Dune::SPTopology< dim >::periodic ( const int  i ) const

inline

determine whether a direction is periodic

Parameters

[in]

i

direction (0 <= i < dimension)

Note

This method only makes sense in case of a single node

Returns

true, if direction i is periodic
