I am doing a problem similar to the steam jet tutorial example but at higher temperatures (640K instead of 373) and a higher proportion of air in the inlet flow. I have tried using Steam5 from the IAPWS library but I continue to get a divergence in something called "newton method". I solved that problem by replacing the steams for water ideal and water liquid and creating a homogenous binary mixture with Antoine Equation used for saturation curve.

I also used a common reference state (P,T) for the specific enthalpy and entropy values for both the states. However, a variable in the tutorial called "SatLHeat" which is the latent heat of vaporization gets an error that it could not be solved. the variable is defined as "Gas.Water Ideal Gas.enthsaturation - Liquid.Water.enthsaturation".

If someone can guide me about this. please ask me if there's more that I need to explain.
