Hi, guys.
I'm trying to get value of gradient of velocity.
But I can't get gradient values at the face.

I mean, first and last nodes value are strange.

I attached graph of 1st, 2nd order gradient of velocity.


How can I get right values?

It's my code.

Code:
DEFINE_ADJUST(my_adjust, d)
{
 Thread *t,;
 cell_t c, ;
 face_t f;
 
 if(N_ITER > 1)
 {
  thread_loop_c(t, d)
  {
   begin_c_loop (c, t)
   {
    C_UDSI(c,t,0) = C_U(c,t);
   }
   end_c_loop (c, t)
  }
  thread_loop_c(t, d)
  {
   begin_c_loop (c, t)
   {
    C_UDSI(c,t,1) = C_UDSI_G(c,t,0)[1];
   }
   end_c_loop (c, t)
  }
  thread_loop_c(t, d)
  {
   begin_c_loop (c, t)
   {
    C_UDSI(c,t,2) = C_UDSI_G(c,t,1)[1];
   }
   end_c_loop (c, t)
  }
 }
}
Thanks. ^^
