hello all,
i am trying to interpret the UDF in ansys fluent 2019
but it shows the parse error in line no. 2.
i think there is some mistake happened in defining PI...
please help

here is the code:

# include "udf.h"
define PI 3.141592654
DEFINE_PROFILE(inlet_velocity,th,i)
{
face_t f;
begin_f_loop(f,th)
double t = (CURRENT_TIME*2-floor(CURRENT_TIME*2))/2; //t is the local time within each period
{
if(t <= 0.218)
F_PROFILE(f,th,i) = 0.5*sin(4*PI*(t+0.0160236));
else
F_profile(f,th,i) = 0.1;
}
end_f_loop(f,th);
}

It's #define.
