Udf problem
Hello all
I am writing a simple udf to get the temperature at each cell during iterations. It is interpreting well. But when I try to run the iterations, it is showing Access_violation error and it comes out. What may be the problem? Also I am having one more doubt. Whether can I include the udf in between the runs? It is leading to always error. Whether is it permissible in Fluent. My udf is given below: #include "udf.h" DEFINE_EXECUTE_AT_END(my_execute) { Domain *d; int ID=2; Thread *t=Lookup_Thread(d,ID); cell_t c; FILE *fp4; int i; real temp=0.; fp4=fopen("temp_zone2.dat","w"); begin_c_loop(c,t) { temp=C_T(c,t); fprintf(fp4,"%g\n",temp); i++; } end_c_loop(c,t) printf("The %d values ", i); fclose(fp4); } |
Re: Udf problem
Karthik ,
you are missing d=getdomain(1), use it before Thread *t=Lookup_Thread(d,ID); Should work then -Ajay |
Re: Udf problem
Since Get_Domain(1) and Thread *t=Lookup_Thread(d,ID) both are same, we can use either of two.
Is it right? Regards Karthick |
Re: Udf problem
No they are not the same .
Thread *t=Lookup_Thread(d,ID) will return a thread pointing to the ID number which you specify .Each boundary or zone is associated with an unique ID. but the other paramter you need which is d the domain pointer is not passed automatically when you use define_execute_at_end you need to get the domain ponter by using d=get_domain(1) -Ajay |
