Mmn11 is on a distinguished road
Can anybody suggest to me how to calculate the surface Nusselt number in a mixed convection simulation in Ansys Fluent?

The simulation is a laminar internal flow problem which includes a 1-meter-long pipe with constant heat flux. If I input the volume average of the fluid temperature as reference temperature, the Nusselt number becomes negative. The fluid properties are temperature-dependent. I created a UDF for them.

Thanks in advance. Cheers!
