Detailed Description

template<unsigned DIM>
class CellBasedSimulationWithPdesAssembler< DIM >

CellBasedSimulationWithPdesAssembler

This is a purpose made elliptic assembler that interpolates the source terms from node onto Gauss points, as for a cell-based simulation with PDEs the source will only be known at the cells (nodes), not the Gauss points.
