Detailed Description

template<class Type>
class Foam::weightedFlux< Type >

Weighted flux interpolation scheme class.

This scheme is used to compute fluxes with variable diffusivity or conductivity, as e.g.

When using the Gauss theorem to compute a gradient, cell centred values need to be interpolated to the faces. Using this scheme, temperature (T) is weighted by thermal conductivity when being interpolated. Similarly, velocity is weighted by diffusivity (D) and the electric potential by the electric conductivity (sigma). Lambda, D or sigma are read from the object registry - the names need to be specified in fvSchemes as e.g.

    gradSchemes
    {
        grad(T)             Gauss weightedFlux lambda;
        grad(u)             Gauss weightedFlux D;
        grad(potential)     Gauss weightedFlux sigma;
    }
