I am trying to run a supersonic ejector simulation using r134a as the working fluid from refprop under the perfect gas model before running it under the real gas model.

I am not able to change the Density to "Ideal Gas" under the "Materials" tab. Attached is the image which shows that i can only choose the real gas option.

May i know how i can change the simulation to run under the perfect gas model?

Update: I figured that i need to run a new material csm file. Does anyone know where i can obtain the relevant properties for r134a? There are 45 properties and i am unsure which material property i need to input.
