I have 10injections in my case. After certain interval i want to calculate the average temperature of particles in each injections. I have written the udf for that and it has compiled but when executed its giving me SIGESEV error and FLUENT crashes after that. Below is the udf.


#include "udf.h"

DEFINE_ON_DEMAND(T_avg)
{
Domain *d;
real tavg = 0;
real Tsum = 0;
real n = 0;
Particle *p;
p = 0;
Injection *I;
I = 0;

real pt = P_T(p);
real flow_time = CURRENT_TIME;




loop(p,I->p)
{
Tsum = Tsum + pt;
n = n + 1;
}
tavg = Tsum/n;

Message("Average Temperatue: %d\n",tavg);


}


P.S. I have never written any udf code so a bit of a novice in this area.
