Description

template<class NumEqVector, typename std::enable_if_t< NumEqVector::size()==3, int > = 0>
class Dumux::ShallowWaterViscousFlux< NumEqVector, >

The viscous momentum flux

\[ \int \int_{V} \mathbf{\nabla} \cdot \nu_t h \mathbf{\nabla} \mathbf{u} dV \]

is re-written using Gauss' divergence theorem to:

\[ \int_{S_f} \nu_t h \mathbf{\nabla} \mathbf{u} \cdot \mathbf{n_f} dS \]

The effective kinematic viscosity \( \nu_t \) can be calculated by adding a vertical (Elder-like) and a horizontal (Smagorinsky-like) part. This enabled by setting "ShallowWater.UseMixingLengthTurbulenceModel" to "true".

For now the calculation of the shallow water viscous momentum flux is implemented strictly for 2D depth-averaged models (i.e. 3 equations).
