I have a 3D geometry, for which i have to calculate Nusselt number using constant Heat flux at the wall throughout the length of the tube. Can i use the FLUENT funcion

Boundary conditions --- wall ----- heat flux or i have to write some UDF for this.

If you wish to simulate a heat flux that is constant with time, and position on the wall, then you can use default FLUENT function. UDF's are used to create variable, functionally dependant boundary conditions.
