UDF temperature variation

Alex E-H

hi. i am attempting to simulate a sinusoidally varying temperature velocity inlet and the following is my udf:

#include "udf.h"

DEFINE_PROFILE(unsteady_temp,thread,index) { face_t f; real T; real t = CURRENT_TIME;

begin_f_loop(f,thread) /* loops over all faces in the thread passed in the macro argument */ { F_PROFILE(f,thread,index) = 10.0 *sin(t*(3.14159/720) /* here stands the profile function as a function of time */ } end_f_loop(f,thread) }

When interpreting in Fluent I am getting the message:

Error: U:\4th_yr\FYP\2nd\Unsteady\unsteady_temperature.c: line 12: parse error.

Can anybody help me with this please?

Alex
