Supercritical CO2 in Comsol

Hi, I am interested in modelling coupled flow and heat exchange with supercritical CO2 as one of the fluids. If the CO2 material in base COMSOL is set to or above the critical pressure and temperature of CO2, will it simulate supercritical properties? or would it be necessary to import in a specific supercritical CO2 module Thanks

Material properties are in the base version, or in a more extensive library in the material library module. You can always create the material properties in your own table that you can create within the model, or place permanently into a user-created portion of the material library. I have used all of the techniques above. In some of my work, I needed an application similar to what you describe, for supercritical hydrogen which can be very nonlinear; especially near the critical point. COMSOL handles all of this very well.
