Abstract : We present a general formulation for the entropy fix which encompasses both Harten and Hyman entropy fixes and HLLE/M schemes. Such a formulation is found to be a simple tool for benefitting from the properties of different methods so as to obtain a positivity preserving version of entropy fix with low dissipation.
