Detailed Description

template<unsigned DIM>
class DistributedBoxCollection< DIM >

A collection of 'boxes' partitioning the domain with information on which nodes are located in which box.

Definition at line 54 of file DistributedBoxCollection.hpp.

Constructor & Destructor Documentation

template<unsigned DIM>
DistributedBoxCollection< DIM >::DistributedBoxCollection ( double  boxWidth,
c_vector< double, 2 *DIM >  domainSize,
bool  isPeriodicInX = false,
int  localRows = PETSC_DECIDE 
)
Parameters
boxWidththe width of each box (cut-off length in NodeBasedCellPopulation simulations)
domainSizethe size of the domain, in the form (xmin, xmax, ymin, ymax) (etc)
isPeriodicInXwhether the domain is periodic in the x direction
localRowsthe number of local rows in a parallel DistributedBoxCollection.

Note that the domain size may be increased because each process should have at least one slice of boxes in the largest dimension. For example, if the box size is 1 and the domain is [(0,0,0), (3,3,3)] then, if there are more than 3 processes the domain will be swollen to [(0,0,0), (3,3,num_procs)]. The user is warned when this happens.

Member Function Documentation

template<unsigned DIM>
void DistributedBoxCollection< DIM >::AddPairsFromBox ( unsigned  boxIndex,
std::vector< std::pair< Node< DIM > *, Node< DIM > * > > &  rNodePairs,
std::map< unsigned, std::set< unsigned > > &  rNodeNeighbours 
)

A method pulled out of CalculateNodePairs methods that adds all pairs of nodes from neighbouring boxes of the box with index boxIndex.

Parameters
boxIndexthe box to add neighbours to.
rNodePairsthe return value, a set of pairs of nodes
rNodeNeighboursthe other return value, the neighbours of each node.

std::vector< std::pair< Node< DIM > *, Node< DIM > * > > &  rNodePairs,
std::map< unsigned, std::set< unsigned > > &  rNodeNeighbours 
)

Compute all the pairs of (potentially) connected nodes for cell_based simulations, ie nodes which are in a local box to the box containing the first node. **Note: the user still has to check that the node pairs are less than the cut-off distance apart.** The pairs are checked so that index1 < index2, so each connected pair of nodes is only in the set once.

Parameters
rNodesall the nodes to be consider
rNodePairsthe return value, a set of pairs of nodes
rNodeNeighboursthe other return value, the neighbours of each node.
