Hello. I want make a condensation-evaporation dynamic simulation and I think it would be good to use a Wet-Steam modell. Anyway, I dont know how to enable this radial button in the Models-->Multiphase Menu. I've read it only works under Density Based Solvers, but I dont even know what these are. Can anybody help me?

Thanks in advance.

If you want to active density base you can go to(define-solver-density based) path.
but i have another question and i will be glad if anyone help me:

when i use the wet steam model with the pressure inlet boundary condition and i set gauge pressure on 90 bar and the temprature on 293k fluent give me a floating point error.

thanks alot
