error in udf, C_VOF
 

Hi to all!

Could anyone tell me

how should I understand the below message,

which I gave from Fluent

after successful compiled my udf:

"Error: Set_Thread_Variables: wta(real)

Error Object: ((constant . )) (profile " " ""))"

I try to pull the Fluent to calculate

the C_UDSI(c,t,2) as a:

"C_UDSI(c,t,2) = C_VOF(c,pt[1])/0.523;"

and in that goal

I have written an udf,

a part of them I attached:

DEFINE_ADJUST(usrfn, domain)

{

Domain *subdomain = Get_Domain(2);

Thread *t;

Thread **pt;

cell_t c;

thread_loop_c(t,subdomain)

{

begin_c_loop(c,t)

{

C_UDSI(c,t,2) = C_VOF(c,pt[1])/0.523;

}

end_c_loop(c,t)

}

}

Could anyone explain me that message?

Thank you very much

Best regards

Paulina
