Somebody, please check my code.
You may open the attached file to understand the question.

#include "udf.h"
DEFINE_ADJUST (unsteady_temperature_name, thread)
{
int position;
face_t f;
real t = CURRENT_TIME;
begin_f_loop (f, thread)
{
F_PROFILE (f, thread, position) = (300+ 0.0066*t - 7*0.000001*t*t)
}
end_f_loop (f, thread)
}

Relation of temperature w.r.t time is different for each part of the pipe.
