Hello,

I am new to UDF scripts and I have tried to make a script using UDF manual, and FLUENT does not complain when I interpret but I don't know if the script is correct. I have a LES simulation and want to make a contour plot of mean vorticity and I don't have any velocity fields from time steps. So I have to make a UDF script in order to get mean vorticity field of velocity fields. The script is as follows

#include "udf.h"

enum{
VORT
};

DEFINE_ON_DEMAND(vorticity_on_demand)
{
Thread*t;
cell_t c;
face_t f;

Domain *domain;
domain = Get_Domain(1);

thread_loop_c(t,domain)
{
begin_c_loop(c,t)
{
C_UDSI(c,t,VORT) = (C_DWDY(c,t)-C_DVDY(c,t)) + (C_DWDX(c,t)-C_DUDZ(c,t)) + (C_DVDX(c,t)-C_DWDY(c,t));
}
end_c_loop(c,t)
}
}

When I interpret, I can't see the vorticity in the contour list and don't know how to make it.
