Backward Compatibility with Version 4.3b

Interior Fluxes Updated

Because the interior flux variable definitions have been revised, models that use interior fluxes in definitions, physics interfaces, or postprocessing show different results in versions 5.0 and later than in earlier versions.

Improved energy balance

Changes introduced in the equation formulation to enable better energy balance may slightly modify the results.

Among the changes, the reference enthalpy, HRef, the value of which is defined up to a constant, is now set to 0 J/kg at the reference temperature and pressure. This changes the absolute values of the enthalpy and several variables based on it. In particular, the value of the convective heat flux is changed. Even the sign may be changed in some cases. However, the quantity of interest, the net convective heat flux, is identical because the shift induced by the change of HRef applies for the enthalpy definition at the inlet as well as at the outlet.
