please check DEFINE_ADJUST code
 

please check follow UDF code
I'm trying to calculate the V_cell (Eulerian particulate velocity) . I must summation the
variables around all particle injected to the control volume.
there are 368 particles injected to the C.V
and I want to storage the V_cell to the UDM5 .
What should I do? please help


DEFINE_ADJUST(v_cell_adjust, domain)
{
real sigma2=0, sigma3=0, v_cell;
Tracked_Particle *tp;
cell_t c = RP_CELL(&(tp->cCell));
Thread *t = RP_THREAD(&(tp->cCell));
Particle *p;
domain = Get_Domain(1);
thread_loop_c(t,domain)
{
begin_particle_cell_loop(p,c,t)
{
for(p=0;p<368;p++)
{
sigma3 += P_MASS(p)*P_VEL(p)[0]*0.65;
}
}
end_particle_cell_loop(p,c,t)
}

C_UDMI(c,t,5)=sigma2/(0.001*C_VOLUME(c,t));
}

thank you
