Hi

I am trying to give user defined inlet in openfoam

i do have udf defined for fluent

here is the code

#include "udf.h"//file that contains definitions for define functions and fluent operations
#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);
}

how can i convert and use it in openfoam
