Detailed Description

Lien cubic non-linear low-Reynolds k-epsilon turbulence models for incompressible flows.

This turbulence model is described in:

    Lien, F.S., Chen, W.L. & Leschziner, M.A. (1996).
    Low-Reynolds-number eddy-viscosity modeling based on non-linear
    stress-strain/vorticity relations.
    Engineering Turbulence Modelling and Experiments 3, 91-100.

Implemented according to the specification in: Apsley: Turbulence Models 2002

In addition to the low-Reynolds number damping functions support for wall-functions is also included to allow for low- and high-Reynolds number operation.
