Detailed Description

template<class G, class RT>
class Dune::GroundwaterEquationParameters< G, RT >

base class that defines the parameters of a the diffusion equation

An interface for defining parameters for the stationary diffusion equation

div j = q; j = -K grad u; in Omega

u = g on Gamma1; j*n = J on Gamma2.

Template parameters are:
