#include <incompressibleLESModels/LESModel.H>
Base class for all incompressible flow LES SGS models.
This class defines the basic interface for an incompressible flow SGS model, and encapsulates data of value to all possible models. In particular this includes references to all the dependent fields (U, phi), the physical viscosity nu, and the LESProperties dictionary, which contains the model selection and model coefficients.
