Detailed Description

template<unsigned DIM>
class DiffusionCaUpdateRule< DIM >

A diffusion update rule for use in cell-based simulations using the cellular CA model.

The probability of moving to an adjacent lattice site is

D*delta_t/(2*delta_x*delta_x)

Where D is the mDiffusionParameter. delta_t is the timestep. delta_x is the separation of the two lattice sites.

Member Function Documentation

template<unsigned DIM>

double DiffusionCaUpdateRule< DIM >::EvaluateProbability ( unsigned  currentNodeIndex, unsigned  targetNodeIndex, CaBasedCellPopulation< DIM > &  rCellPopulation, double  dt, double  deltaX, CellPtr  cell  )

virtual

Calculate the probability of a given move.

Uses random diffusion to each neighbouring node, scaled according to distance.

Parameters

currentNodeIndex	The index of the current node/lattice site
targetNodeIndex	The index of the target node/lattice site
rCellPopulation	The cell population
dt	is the time interval
deltaX	defines the size of the lattice site
cell	a pointer to the cell (needed if more than one cell per lattice site

Returns

The probability of the cell moving from the current node to the target node
