i am trying to use following UDF which includes two boundary conditions.
but it shows parse error in line 19 when i try to load it in FLUENT. I dont know what the problem is


#include "udf.h"
#include "unsteady.h"
DEFINE_PROFILE(transient_velocity, thread, index)
{
face_t f;
real x[ND_ND];
real t = CURRENT_TIME;
real tc;
real v [100];
int N;
int j;
real y;
real i = N_TIME;
begin_f_loop(f, thread)
{
y = i;
N=t/0.84;
tc=(t-0.84*N)*2.741;
v [j] = -29.88+24.15*cos(tc)+44.1*sin(tc)+15.47*cos(2*tc)-24.42*sin(2*tc)10.33*cos(3*tc)-0.3837*sin(3*tc)+0.8866*cos(4*tc)+1.568*sin(4*tc);
F_CENTROID(x,f,thread);
y = x[1];
F_PROFILE(f,thread,index) = v [j]/2;
}
end_f_loop(f, thread)
}

DEFINE_PROFILE(unsteady_pressure, thread, position)
{

float t, pressure; face_t f;

/* Get real flow time from fluent using RP_Get_Real command*/

t = RP_Get_Real("flow-time");

/* Set pressure dependant on time for pulse duration */
if (t<=0.00821) { pressure = 60000*sin(3.14159*t/0.00821); } else { pressure = 0; }

/* loop over the whole boundary condition */

begin_f_loop(f, thread) {

F_PROFILE(f, thread, position) = pressure; } end_f_loop(f, thread)

}
