Member Function Documentation

void RectangleStencil::addFlux ( unsigned int  meshIndex, vector< double > &  f, const vector< vector< double > > &  S, const vector< double > &  diffConst  ) const

virtual

computes the Flux f in the voxel on meshIndex. Takes the matrix of molNumber[meshIndex][pool] and the vector of diffusionConst[pool] as arguments.

Implements Stencil.
