Parabolic Velocity UDF
 

Hey guys,
trying to make a UDF for a parabolic velocity profile (that varies in x-direction). But im not sure if this is correct:

#include "udf.h"


DEFINE_PROFILE(inlet_y_velocity, thread, position)
{
real y[ND_ND]; /* this will hold the position vector */
real x;
face_t f;

begin_f_loop(f, thread)
{
F_CENTROID(y,f,thread);
x = y[1];
F_PROFILE(f, thread, position) = "parabolic profile eqn in terms of x";
}
end_f_loop(f, thread)
}

hi, i thik that this udf is correct so you must try it.:)
