Hi
I have such a piece of code:

# include "udf.h" # define domain_ID 1 DEFINE_ADJUST(adjust_gradient, domain) { Thread *t; cell_t c; face_t f; domain = Get_Domain(domain_ID); /* Fill UDS with the variable. */ thread_loop_c (t,domain) { begin_c_loop (c,t) {
// assign temperature values into User scalar 0
C_UDSI(c,t,0) = C_T(c,t); } end_c_loop (c,t) } }

I compiled and hooked this, allocated UDS (without flux) and did 50 iterations.
I checked contours of Static temperature and User scalar 0 and they
are not the same!!! Why it is so? I just assign temperature values
into User scalar 0 and it does not work. Please help.

No answer, but I reformat your code because it is very difficult to read in this way. You can do this yourself by adding
HTML Code:
[CODE][/CODE]
around your code.

Your last code, in a readable format, is this:
Code:
# include "udf.h" 
# define domain_ID 2  
DEFINE_ADJUST(adjust_gradient, domain) {
   Thread *t;
   cell_t c;
   face_t f;
   domain = Get_Domain(domain_ID);
    /* Fill UDS with the variable. */
   thread_loop_c (t,domain) {
        begin_c_loop (c,t) {
            C_UDSI(c,t,0) = C_VOF(c,t);
        }
        end_c_loop (c,t)
     }
 }

Ok thank you.
I took the code from here (at the end)

http://jullio.pe.kr/fluent6.1/help/html/udf/node107.htm

it is from documentation and it does not work. Why???
