I know that the enthalpy of the fluids at inlet and outlets are estimated by fluent based of Tref = 298.15 K, based on this I am getting negative values of enthalpy at the inlet and outlet as my inlet temperature is 292.55 K at inlet.

So i am trying to change this Tref so that enthalpy is not negative.

There is no effect on changing the reference temperature from reference value tab

Hence I would like to know how do we directly change the Tref value

There's a Tref in the material properties depending on what models are set. Be very careful that changes you make are consistent throughout the model. We're usually interested in the change in value so it's not normally something we worry about.
