getCouplingCellSize()

template<unsigned int dim>

tarch::la::Vector< dim, double > coupling::indexing::IndexingService< dim >::getCouplingCellSize ( ) const

inline

returns the vector size of each coupling cell.

Returns

the size of the coupling cells (dimensional)

getGlobalMDDomainOffset()

template<unsigned int dim>

tarch::la::Vector< dim, double > coupling::indexing::IndexingService< dim >::getGlobalMDDomainOffset ( ) const

inline

returns the offset, i.e. the lower,left... corner coordinate, of the MD domain.

Returns

the offset of the MD domain

getGlobalMDDomainSize()

template<unsigned int dim>

tarch::la::Vector< dim, double > coupling::indexing::IndexingService< dim >::getGlobalMDDomainSize ( ) const

inline

returns the global domain size of the MD domain (excl. ghost layer which naturally is not part of MD).

Returns

the total size of the md simulation domain (dimensional)

getRanksForGlobalIndex()

template<unsigned int dim>

std::vector< unsigned int > coupling::indexing::IndexingService< dim >::getRanksForGlobalIndex	(	const BaseIndex< dim > &	globalCellIndex,
		unsigned int	topologyOffset ) const

Determines all ranks that contain a certain global BaseIndex. Ripped from deprecated IndexConversion.

Parameters

globalCellIndex	index to be looked up
globalNumberCouplingCells	global number of cells in BaseIndex domain EXCLUDING global ghost layer cells.

Returns

vector of all cells which contain the index
