sorry about my native langauge is not english

i study tornado(Diwakar Natarajan's paper). I want to see resault with fluent
my question is how make a udf file tangential velocity?

like this v_(R_0)

(H and R is fixed number and U is radial velocity)


AND i make radial veloicity udf code. is it correct?
#define B 1./7.
#define zone 0.25
#define u 10
DEFINE_PROFILE(inlet_x_velocity, t, i)
{
real x[ND_ND]; /* variable declarations */
real z;
//real r0 , h0 ;
face_t f;

//r0 = 1.52;
//h0 = 0.41;


begin_f_loop(f, t)
{
F_CENTROID(x, f, t);
z = x[2];
F_PROFILE(f, t, i) = u * pow(z/ zone, B);

}
end_f_loop(f, t)
}

thank you for read this message and help me please
