Variable heat flux with UDF with respect to Duct Area

Hi to All
I am going to analyses Heat Transfer with Variable heat flux with respect to Area of Tube.
I will be Grateful if anyone could guide me about UDF code.

Best Regards

If you know the functional relationship, I think the easiest way is to have heat flux as a function of position.

You just need to make UDF for a profile. Check out the tutorials or examples in the Fluent help documentation to get familiar (i.e. inlet velocity profile UDF). The UDF sub-forum is loaded with info as well.
