There's no such thing like a Nu calculation in Fluent, but you can back it out from the Fluent results. First calculate the 'heat transfer coefficient' for a given problem using the correct reference temperatures. Then using the appropiate values for Cp, thermal conductivity and hydraulic diameter you can obtain a Nusselt number.
