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