Default Equation of State for the NIST Real Gas Model

Hello everyone,

I am running a simulation involving supercritical methane. The NIST Real Gas Model, when loaded as per the Users Guide, works fine but it and the Helmholtz Free Energy equation of state it uses are limited to an upper temperature limit of 625K which will not cut it for me.

Now, after some investigation, I've noticed that the property file methane.fld contains coefficients for other EOS as well. Is it possible to change which one Fluent defaults to? If yes, how do I do it?

Thank you!
