Detailed Description

template<unsigned DIM>
class BoxCollection< DIM >

A collection of 'boxes' partitioning the domain with information on which nodes are located in which box Not archived - in cell_based constructed in NodeBasedCellPopulation constructor.

Constructor & Destructor Documentation

template<unsigned DIM>

BoxCollection< DIM >::BoxCollection	(	double	boxWidth,
		c_vector< double, 2 *DIM >	domainSize
	)

Constructor

Parameters:

boxWidth	the width of each box (cut-off length in NodeBasedCellPopulation simulations)
domainSize	the size of the domain, in the form (xmin, xmax, ymin, ymax) (etc)

Definition at line 92 of file BoxCollection.cpp.

Member Function Documentation

template<unsigned DIM>

unsigned BoxCollection< DIM >::CalculateContainingBox ( Node< DIM > * pNode )

Calculate which box this node is contained in.

Parameters:

pNode address of the node

template<unsigned DIM>

unsigned BoxCollection< DIM >::CalculateContainingBox ( c_vector< double, DIM > & rLocation )

Calculate which box a point is contained in

Parameters:

rLocation The point

Definition at line 176 of file BoxCollection.cpp.

template<unsigned DIM>

void BoxCollection< DIM >::CalculateNodePairs	(	std::vector< Node< DIM > * > &	rNodes,
		std::set< 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:

rNodes	all the nodes to be consider
rNodePairs	the return value, a set of pairs of nodes
rNodeNeighbours	the other return value, the neighbours of each node.

std::set< unsigned > BoxCollection< DIM >::GetLocalBoxes ( unsigned boxIndex )

Get the set of all the local boxes, i.e. itself and its nearest-neighbours.

Parameters:

boxIndex the index of the box

void BoxCollection< DIM >::SetupLocalBoxesHalfOnly ( )

Set up the local boxes (ie itself and its nearest-neighbours) for each of the boxes. Just set up half of the local boxes (for example, in 1D, local boxes for box0 = {1} local boxes for box1 = {2} not {0,2}, and so on. Similar to 2d, 3d.
