你可能误解了， 我的意思是 face_t f; 这句话在程序中有无存在价值？cell_t,face_t和thread的区别我在手册上看到过
同样非常感谢...

# 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)
    }
}
