I simulated boiling process ，and I want to stop calculation when the vapor appear，the multiphase model is Mixture，primary phase is water，vapor is secondary。I made an udf,but it just fit for 2D geometry，if used in3D geometry，it would be error，I need some help，thank you！the udf wrote as follow：

#include "udf.h"
# define domain_ID 3
real stop_coeff=1;
real sum_vof=0.;
real sum_volume=0.;
DEFINE_ADJUST(stop_vof, domain)
{
Thread *t;
cell_t c;
face_t f;
domain = Get_Domain(domain_ID);

thread_loop_c (t,domain)
{
begin_c_loop (c,t)
{
sum_vof += C_VOF(c,t);
}
end_c_loop(c,t)
}
if(sum_vof >0)
{
real stop_coeff=1;
}
else
{
stop_coeff+=1;
}
thread_loop_c(t,domain)
{
begin_c_loop(c,t)
{
C_UDMI(c,t,0) = stop_coeff;
C_UDMI(c,t,1) = C_P(c,t);
C_UDMI(c,t,2) = C_VOF(c,t);
}
end_c_loop(c,t)
}
}
