udf for temperature inlet in fluidized bed
 

hi all

i trying to simulate heat transfer distribution in fluidized bed.
in my simulation air temperature inlet is a function of time.

i don't know how to define it in fluent software.

Please help me
Thanks.

Hi;
I think you must use define-adjust to update air temperature in every iteration.

dear mehdi
I've used this code as follows and my result is almost good do you think this code is correct?
thanks
#include "udf.h"
DEFINE_PROFILE(transient_temperature, thread_g, position)
{
face_t f;
real t=CURRENT_TIME;
begin_f_loop(f,thread_g)
F_PROFILE(f,thread_g,position)=(3.4*t)+295;
end_f_loop(f,thread_g);
}
