hello all
i write a udf code (below) to simulate power law fluid but it doesn't work . it has some errors . please help me .

#include "udf.h"

DEFINE_PROPERTY(user_power_law,c,t)

{

real visc_dyn_min=0.0001;
real visc_dyn_max=10000;
real index_n=0.78;
real k=1.65;
real T0=0;
real temp=C_T(c,t);
real mu_app;
real mu_temp;

mu_temp=k*pow(C_STRAIN_RATE_MAG(c,t),index_n-1)*exp(T0/(temp));

if (N_ITER<1)
{
mu_app=k;
}
else if((N_ITER>=1)&&
(mu_temp>visc_dyn_min)&&
(mu_temp<visc_dyn_max))
{
mu_app=mu_temp;
}
else if ((N_ITER>=1)&&
(mu_temp>=visc_dyn_max))
{
mu_app=visc_dyn_max;
}
else if ((N_ITER>=1)&&
(mu_temp<=visc_dyn_min))
{
mu_app=visc_dyn_min;
}
return mu_app;
}


Error: line 41: label "count2" not found (pc=517).

N_ITER can only be utilized in compiled UDFs.
