3 years ago What result do you get for quality in refprop 9? Do the densities differ between REFPROP 9 and REFPROP 10?

3 years ago It looks like everything is correct, it's just that in version 9 this state was not calculated, but now it is! Thank you!
REFPROP 911
REFPROP 10

Everything works correctly in REFPROP 9. When checking in Excel, the correct error is also returned, but the new function is used in the Excel add-in. **Expected behavior:** ierr > 0 **Actual behavior:** ierr = 0 ### Versions **REFPROP Version:** [REFPROP 10.0] **Operating System and Version:** [Win10] **Access Method:** [C#] ### Additional Information  Using names: _PHFLSH(ref parameters.Pressure, ref parameters.Enthalpy, molar_fraction, ref parameters.Temperature, ref parameters.Density, ref parameters.DensityLiquid, ref parameters.DensityVapor, molar_fractionL, molar_fractionV, ref parameters.Quality, ref parameters.InternalEnergy, ref parameters.Entropy, ref parameters.CV, ref parameters.CP, ref parameters.SoundSpeed, ref parameters.Error, herr, herr.Capacity);
