Detailed Description

template<class BasicMomentumTransportModel>
class Foam::simplifiedViscousStress< BasicMomentumTransportModel >

Simplified linear viscous stress momentum transport model base class.

For incompressible uniform viscosity flow in which the transpose and dilatation terms in the linear stress model are formally zero.

This model can also be useful for complex surface film cases in which the transpose and dilatation terms are relatively very small compared to the wall surface stress and can safely be ignored avoiding potentially large numerical errors around sharp corners.
