#include <incompressibleLESModels/GenSGSStress.H>
General base class for all incompressible models that directly solve for the SGS stress tensor B.
Contains tensor fields B (the SGS stress tensor) as well as scalar fields for k (SGS turbulent energy) gamma (SGS viscosity) and epsilon (SGS dissipation).
