I wanna write a UDF which is applied to a boundary, say, UDF like the following: #include "udf.h"

DEFINE_PROFILE(x_velocity, thread, index) {

float t, x_velocity;

float Area;

real x[ND_ND];

real y;

face_t f;

begin_f_loop(f, thread)

{

t = RP_Get_Real("flow-time");

Area =

x_velocity = Q/Area;/*Q is the flow rate*/

F_PROFILE(f, thread, index) = x_velocity;

}

end_f_loop(f, thread) }

how to calculate the area "Area"?
