Does anyone know where to get properties for R410A, R407A and R507 at pressures between 100 and 500 bar to use in making a component beyond what is included in coolprop? All would be in the supercritical state. Of course the next question would be to how best to model in DWSIM but without properties... Thanks in advance.

hi Daniel the crash no longer happens in tonights update but now just gives an error

I have a basic simulation with one exchanger and two streams. One stream is 50-50 EG/water the other is R134a. I've tried coolprop for r134a and mod unifac for the eg/water and it won't calculate. If I only use modunifac the simulation crashes out everytime.

what is the correct property package for this?

Does anyone have experience knowing what the outlet temperatures should be.
