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.
