Hi,
I am a beginner in udf and would love to have your help in the following problem. Thank you very much in advance

I have a udf for accessing the cell information such as its x,y,z coordinate, mixture fraction of species.
Everything is fine, except i dont know how to get this data written into a text file.
I thought it would get displayed in one of the "results" so that i can just "write" it into a file..But now it gets displayed only in the boundary conditions.

Please can someone tell me how do i extract this information on to a text file. the program is as below.

#include "udf.h"
DEFINE_ADJUST(fonction_retour,domain)
{
cell_t c;
Thread *tc;
real xc[ND_ND],x,y,z,tempe,mass_w_i;
int i;
thread_loop_c(tc, domain)
{
begin_c_loop(c, tc)
{
C_CENTROID(xc,c,tc);
x=xc[0];
y=xc[1];
z=xc[2];
tempe= C_T(c,tc);
mass_w_i = C_YI(c,tc,i);
}
end_c_loop(c, tc)
}
}
