Hi,
I have another problem...
Just to try, I wanted to put different viscosities to the pair cells and impair cells...

#include"udf.h"
DEFINE_PROPERTY(cell_viscosity, cell, thread)
{
real mu_lam;
cell_t c;
int i;
for (i=1, i<200, i++)
if ((cell_t ci %2)==0)
mu_lam = 2.;
else
mu_lam = 1.;
return mu_lam;
}

But it doesn't work... I'm new with both Fluent and C++...

If anyone could help..
Thanks!!
