SOS!About water-vapor

Hi, everyone! IĄŻm modeling water-vapor flows through a converge-diverge nozzle using commercial code. For compressible flows, many commercial codes think the idea gas law is the appropriate density relationship. However, the water vapor IĄŻm using is 0.6Mpa, so in my opinion, it canĄŻt be thought as idea gas. Unfortunately, I couldnĄŻt find the UDF (User Defined Function) for density. Could anybody kind enough to give me some advices on how to set the physical properties. Anything about FLUENT, CFX, or ANSYS is welcome! All thanks given to you for your help!

Thank you for your help. I had found the UDF(user defined function) in FLUENT.(because i am more familiar with that code). Now my question is how can i decide the state of the fluid on the basis of the temperature which is equal to that of the saturated water-vapor?
