Hello everyone,

I have made some measurements concerning the heat transfer coefficient and i would like to apply these values into the model instead of using the ones calculated by Fluent.
Unfortunately, there is no example code on applying HTC by UDF in the manual. But I found some codes here in the forum I am trying to apply.
For practise, I would first like to start with a function that configures an HTC of 10000 at the whole interface between solid and fluid. I use this UDF for that:


DEFINE_PROFILE(pressure_profile,t,i) {

face_t f; double htc;

begin_f_loop(f,t)

{

htc=100000(F_T(f,t), 2.0);

F_PROFILE(f,t,i) = htc;

} end_f_loop(f,t) }


Unfortunately this UDF does not work. Can someone explain me where the problem is? Besides that, can someone tell me how I actuall hook the UDF?


Best regards
