Default Regarding Entropy Generation

Thermal_engg is on a distinguished road
Hey everyone,
I am modelling a rectangular natural circulation loop with isothermal heat source and heat sink and the rest of the surfaces adiabatic.This whole system is isolated from the surroundings.
I am using carbon dioxide as a fluid and employing NIST real gas model in the subcritical region of CO2.
I have specified uniform wall thickness throughout and enabled the "Shell Conduction" option.

I want to calculate entropy generation in the various regions of the loop so as to optimize its design.Does Fluent readily do this or do I have to calculate using the post-processor.
Any help is appreciated.Thnx
