Detailed Description

AdvectionDiffusionModel is a base class for description of a physical process described by the advection-diffusion partial differential equation (PDE). The derived classes define input parameters and implement methods that calculate coefficients of the PDE. These methods are then used by a template class for numerical solution, whose specialization derives from the model class.
