I see that there are 2 options for CO2, CO2 and CO2- . I was wondering if Ansys will acknowledge that it is in supercritical phase if I set a temperature and pressure above the critical point. Or do I have to specify somewhere that this is a real gas and not an ideal gas.&nbsp;<\/p>\n<p><\/p>\n<p>I have tried to follow something online to use real gases from the NIST REFROP but that disables the built in database in Ansys and I was no longer able to select the Aluminum (which is built into Ansys database).<\/p>\n<p><\/p>\n<p>&nbsp;<\/p>\n<p><\/p>\n<p>I have attached a picture of my model.
