Problem in Parallel UDF

Giacomo de Renzi

Hello, I've a problem using UDF with Parallel Computing: the main part of the UDF is a DEFINE EXECUTE AT END macro that calculates the average temperature on a face. In Serial Computing it works, but in Parallel Computing (and I need it!!!) it doesn't work fine because the macro is read by all partitions, while the face belongs to only one partition, how can I select the partition that is involved in the macro??

the UDF is attached below:

DEFINE_EXECUTE_AT_END(DEAE_T_rack_NO1_in) { real A_tot = 0.0; real ma_sum = 0.0; real T_sum = 0.0;

step = CURRENT_TIMESTEP; current_time = CURRENT_TIME; if (current_time > step) { Domain *d = Get_Domain(1);

real A[ND_ND]; Thread *t; face_t f; int id=62 ; /* ZONE ID RACK-NO1-IN */ t= Lookup_Thread(d,id);

begin_f_loop(f,t) { F_AREA(A,f,t); T_sum = T_sum + (F_T(f,t) * NV_MAG(A)); ma_sum = ma_sum + NV_MAG(A); } end_f_loop(f,t)

T_rack_NO1_in=T_sum/ma_sum; RP_Set_Real("controllo_no1",T_rack_NO1_in); } else {

T_rack_NO1_in = t_init; RP_Set_Real("controllo_no1",T_rack_NO1_in);

}

printf("T_rack_NO1_in: %g\n", T_rack_NO1_in); }

thank You, I hope someone could help me.. Giacomo de Renzi
