Dear Sis,

Please urgently, how to simulate heat exchanger in fluent? do i have to build a model in gambit first? or there is a settled model in fluent, because I done the following :
Opened Fluent
Choosed 3d version
Selected Define ---- User-Defined --- but I found Heat exchanger not active
I logged to chapter 7.25 of heat exchanger models and chapter 33.3 of user defined for heat exchanger in fluent help but I couldn’t activate the heat exchanger option.
They said I have to make a boundary condition file by (file ---- write-bc) but I couldn’t find this option also to make (define ---- user-defined ---- heat-exchanger) but also it gave me invalid command.

So please advice do I have to make heat exchanger model in gambit first or use fluent directly and how?
best regards
