Next time, can you just copy your code, not a picture of your code?

You have already a typo in the first line. It is include, not inclide.

d=Get_Domain(1) ;
int id=4;
Thread t=lookup_thread(1,4);
double Den = 0.655 ;
thread_loop_t (t,d){
begin_t_loop(t,d)
c_r(c,t) = Den ;
c_t(c,t) = 300 ;
end_t_loop
}
}

#include "udf.h"

DEFINE_ADJUST(M_Dens,d)
{
int id=4;
Thread *t=Lookup_Thread(d,id);

double Den = 0.655 ;

begin_c_loop(t,d)

Hi - thank you for attention .
I read Fluent's udf manual - but unfortunately I did not find a good example to illustrate these phrases.
