High friends,

I need to calculate Secondary Phase average temperature using a UDF in my multiphase problem. There are two phases here as water-liquid and air; I wrote the following UDF to calculate and show the variable at the end of every time-step; as shown there is a Get_Domain argument at written UDF. But no matter of what number I write between the parantheses of Get_Domain, shown temperature dosn't change and I think it shows the mixture average temp every time. How can I get the seconadry phase avergae temperature.

Regards,

#include "udf.h"

DEFINE_EXECUTE_AT_END(execute_at_end)
{
real sumtemp = 0;
real sumvolume = 0;
real twater;
Domain *d;
Thread *t;
cell_t c;
d = Get_Domain(2);

thread_loop_c (t,d)
{
/* loop over all cells in secondary phase cell threads */
begin_c_loop (c,t)
{
sumtemp1 += C_T(c,t) * C_VOLUME(c,t);
sumvolume1 += C_VOLUME(c,t);
}
end_c_loop (c,t)
}

twater = sumtemp / sumvolume;
printf("temp is: %g\n", twater);
}
