DEFINE_PROFILE(av_temp_out,t, index)

real tavg;

real x[ND_ND],y,tavg1,s,s1;

face_t f;

s=0;

I didn't find any answers on how to make it, and therfore i made it in another way:

#define WALL_ID 14 #define WALL_ID1 15

DEFINE_EXECUTE_AT_END(aver_temp)

{

Domain *d; Thread *t; real x[ND_ND],y,tavg1,s,s1,tavg; face_t f; real time=CURRENT_TIME; d = Get_Domain(1);

s=0; tavg1=0;

thread_loop_f (t,d) {

if(THREAD_ID(t)==WALL_ID)

{

begin_f_loop(f,t)

{

F_CENTROID(x,f,t);

y=x[1];

tavg=F_T(f,t);

s1=y*y*3.14;

s+=s1;

tavg1 +=tavg*s1;

}

end_f_loop(f,t)

} }

tavg1/=s; thread_loop_f(t,d) {

if (THREAD_ID(t)==WALL_ID1) {

begin_f_loop(f,t)

{

if (time<=86400)

F_T(f,t)=tavg1;

else F_T(f,t)=290;

}

end_f_loop(f,t) }

}

}
