hi all !
I have a problem , in my project i have to compute heat transfer coefficient , Nusselt number and heat flux values.
I am working on simple natural convection over flat plates vertical horizontal or inclined on 2D no matter.
My problem is , numerical results that i calculated and Fluent results are diferent.
Because of that i need to write udf in order to have numerical results in fluent
Here is the problem , i can't use some macros like DEFINE_PROFILE to assign a new htc in boundry condition(in convection option) , because i have constant temperature or heat flux values and for now i am studying on only about natural convection , i tried to use DEFINE_HEAT_FLUX macro but i guess my code isn't correct .
Anyone help me about it , or any sugestion ?
