Dear all

I am trying to implement a real gas equation of state, to do that, I created several functions, variables, compossed functions, conditional statements in the material section. These relations are needed to solve the compressibity factor Z ( which is this case is obtained with analytical relations for a cubic equation). I ran the k-e high mach number solver to calculate a helium expansion through a 9 [um] orifice. However, I am getting the exact same solution for the ideal gas law density and the real gas density model implemented. I attach the model.

Thank you

David.
