Hi everyone,

I am modeling a reactor for Fischer Tropsch Synthesis on Fluent, and I need to write a UDF for calculating its reaction rate using activity, fugacity coefficients, and Gibbs Free Energy through Peng-Robinson Equation of State. I am struggling to write the UDF as I don't know how to get hold of things like compressibility factor and covolumes. Has anyone ever tried to find the quantities like Gibbs free energy or fugacity in Fluent?

Thanks in advance.
