How does ANSYS Fluent calculate its enthalpy?

Hey guys!
I am working with ANSYS Fluent at the moment and now there appeared a question. I wrote the User-Defined Funtions, one for the density and one for the viscosity - both dependent on the enthalpy. While running the calculation with one of these UDFs I set the other parameter (density or viscosity) constant. All other settings stayed the same in those two calculations. Now ANSYS Fluent gave me different enthalpy-values in both calculations. Now I am a bit confused because the density and the viscosity respectively should be calculated based on the enthalpy-values and not the other way around. So can anyone help me and explain to me why I have different enthalpy-values when I just changed the terms for density and viscosity? Thanks up front!

hi, did you figure out the enthalpy calculation in FLUENT?
