DEFINE_DPM_OUTPUT

wzslj

Hi,I want to use the DEFINE_DPM_OUTPUT to get the droplet information(spray dry) form the sample plane that i constructed according to the command:Surface/plane.The DEFINE_DFINE_OUTPUT is shown below :

#include "udf.h" #include "dpm.h" DEFINE_DPM_OUTPUT(injetion_output, header, fp, p, thread, plane) { char name[100];

if (header)

{

if (NNULLP(thread))

printf(fp,"(%s %d)\n",thread->head->dpm_summary.sort_file_name,11);

else

printf(fp,"(%s %d)\n",plane->sort_file_name,11);

printf(fp,"(%10s %10s %10s %10s %10s %10s %10s"

" %10s %10s %10s %10s %s)\n",

"X","Y","Z","U","V","W","diameter","T","mass-flow",

"time","melt-index","name");

}

else

{

sprintf(name,"%s:%d",p->injection->name,p->part_id);

printf(fp,

"((%10.6g %10.6g %10.6g %10.6g %10.6g %10.6g "

"%10.6g %10.6g %10.6g %10.6g %10.6g) %s)\n",

p->state.pos[0], p->state.pos[1], p->state.pos[2],

p->state.V[0], p->state.V[1], p->state.V[2],

p->state.diam, p->state.temp, p->flow_rate, p->state.time,

p->user[0], name);

} }

I compiled the programme after the spray dry calculation is completed.The compiling process is success,but when i carry the order:Report/Discrete phase/sample, the data is unable to appendix the to file. Also the pointers to the particle *p and to the thread *t are all NULL

Who can tell me why?

Thank you very much!
