Detailed Description

template<unsigned DIM>
class VolumeDependentAveragedSourceEllipticPde< DIM >

An elliptic PDE to be solved numerically using the finite element method, for coupling to a cell-based simulation.

This class inherits from AveragedSourceEllipticPde and may only be used with a NodeBasedCellPopulation, since it assumes that each cell is associated with a Node object.

The PDE takes the form

Grad.(D*Grad(u)) + k*u*rho(x) = 0,

where the scalars D and k are specified by the members mDiffusionCoefficient and mSourceCoefficient, respectively. Their values must be set in the constructor.

The function rho(x) denotes the local density of non-apoptotic cells. This quantity is computed for each element of a 'coarse' finite element mesh that is passed to the method SetupSourceTerms() and stored in the member mCellDensityOnCoarseElements.

For a point x, rho(x) is a weighted sum of the non-apoptotic cells whose centres lie in each finite element containing that point, scaled by the area of that element. The weighting assigned to each cell is given by the square of the radius of the associated node, which is accessed using the GetRadius() method.
