Hi guys.

I already calculate total volume of cell.

Use this code.
----------------------------------------------------------
#include "udf.h"

DEFINE_ON_DEMAND(demo_calc)
{
real volume, vol_tot;
Domain* domain;
Thread* t;
cell_t c;

vol_tot = 0.;
domain = Get_Domain(1);

thread_loop_c(t, domain)
{
begin_c_loop(c, t)
{
volume = C_VOLUME(c, t);
vol_tot += volume;
}
end_c_loop(c, t)
}
Message("Total Volume=%g", vol_tot);
}
------------------------------------------------------

After that, I want to calculate each (particle) cells volume.

But I can't find it.

Is there any sample code?

You could add this line to display cell volume:

You could write cell volume to a text file, etc.
