Hello all,

I want to calculate the material properties using the particle data. Is it possible?

For checking, I am trying to calculate the no.of particles in each cell using the DEFINE_PROPERTY MACRO.

#include "udf.h"
#include "pdf_transport.h"
#include "dpm.h"
#include "cl_dpm.h"
FILE *fp;

DEFINE_PROPERTY(cell_abs_coeff, c, t)
{
Particle *p;
Domain *d=Get_Domain(1);
int iter = 0;
Alloc_Storage_Vars(d, SV_DPM_PARTICLE_BIN, SV_NULL);
FLUENT_EXPORT void bin_particles_in_cells(Domain *d, cxboolean true);

begin_particle_cell_loop(p,c,t)
{
iter++;
}
end_particle_cell_loop(p,c,t)

Free_Storage_Vars(d, SV_DPM_PARTICLE_BIN, SV_NULL);

fp = fopen("results.dat", "a");
fprintf(fp,"%d\t\n",iter);
fclose(fp);

return 0;
}

But it seems like, it does not enter into the particles loop. I am just keep getting zero for each cell.

Can anyone please tell me what I am missing?

Thanks in advanced.
