Hi everyone,

I want to impose a profile of velocity in the "inlet" of my geometry, so I want to create an UDF, since this is the first time I use it I ask your help

I want to impose this profile : Ux = 250*y^2,

I write this (but I don't now if I impose this profile in the all inlet or not and if this is right or not) :

#include "udf.h"
    
DEFINE_PROFILE(x_velocity,t,i)
  {
  real x[ND_ND];

real y;  

  face_t f;

begin_f_loop(f,t)  
 {
  F_CENTROID(x,f,t);
  y = x[1];
  

  F_PROFILE(f,t,i) = 250*pow(y,2);

}
  end_f_loop(f,t)

Thanks for help
