Hello,
I am working with DPM and trying to get the trapped particle coordinates.
I am using this UDF to get the coordinates.
#include "udf.h"
DEFINE_DPM_BC(dpm_coordinates_0412,p,t,f,f_normal, dim)
{ FILE * f1; float x=0; float y=0; float z=0;
f1 = fopen ("Z:\\dpm_coordinates_0412_xyz.txt", "a");
x=P_POS(p)[0];
y=P_POS(p)[1];
z=P_POS(p)[2];
fprintf (f1, "%f %f %f\n",x,y,z);
fclose(f1);
return PATH_ABORT; }

Suppose, I release 1400 particle and 700/800 particle trapped. But using this UDF I am getting lots of coordinates. How can I get the exact number of coordinates which are trapped.

Could you please help me.
Regards,
Saidul
