Hi guys. I always thank you for your help.

I learn lots of info. and techniques for udf.

However, I have one problem.

I finished calculating cell volumes and centroids.

This is my code
=====================================
#include "udf.h"

DEFINE_ON_DEMAND(demo_calc)
{
real volume, vol_tot;
Domain* domain;
Thread* t;
cell_t c;
real x[ND_ND];
real y, z;

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

thread_loop_c(t, domain)
{
begin_c_loop(c, t)
{
volume = C_VOLUME(c, t);
Message("Cell Volume=%g\n", volume);
vol_tot += volume;
C_CENTROID(x, c, t);
y = x[1];
z = x[2];
Message("x_centroid=%g, y_centroid=%g, z_centroid=%g\n", x[0], x[1], x[2]);
}
end_c_loop(c, t)
}
Message("Total Volume=%g\n", vol_tot);
}
============================================

But, I cannot find method which save these data (each cells volume, centroid coordinates) to txt file.

Naturally, it is possible by mouse (copy and paste to notepad)

But I want to know how can i automate this result.

Waiting your help

From memory:

#include "udf.h" 

DEFINE_ON_DEMAND(demo_calc)
{
real volume, vol_tot;
Domain* domain;
Thread*	t;
cell_t c;
real x[ND_ND];
real y, z;
file *foutput;

vol_tot = 0.;
domain = Get_Domain(1); 
foutput = fopen("outputfile.txt",a);

thread_loop_c(t, domain)
{
begin_c_loop(c, t)
{
volume = C_VOLUME(c, t);
fprintf(foutput,"Cell Volume=%g\n", volume);
vol_tot += volume;
C_CENTROID(x, c, t);
y = x[1];
z = x[2];
fprintf(foutput,"x_centroid=%g, y_centroid=%g, z_centroid=%g\n", x[0], x[1], x[2]);
}
end_c_loop(c, t)
}
fprintf(foutput,"Total Volume=%g\n", vol_tot);
fclose(foutput);
}
