thomas,thanks for your attention,but i am afraid that you have not yet understand my question,I am asking in the wall loop,is there any command to get the face on its shadow wall?

for example ,we can use c0=F_C0(f,ft) and c1=F_C1(f,ft) to get adjacent cells to that wall face within the wall thread loop,can we also get the adjacent face on the shadow wall in the wall loop ?

I am not sure I've made it clear enough or not.

OK i see what you mean. By definition only F_C0 exist at a boundary condition. So when you loop the faces over the wall, F_C0 will give you the adjacente cells. When you loop the faces over the wall shadow, F_C0 will give you the adjacente cells in the opposite side of the wall. OK ? To convince yourself creat a UDMI = 1 for the cell adjacent to wall and UDMI = 2 for the cells adjacent to wall shadow Hope this help

ok,let me tell you what i m doing now,

..................

begin_f_loop(f_w,ft_w)

{

F_UDMI(f_w,ft_w,0)=function1;

/*I guess there should be some connections between f_w and f_shadow ,so that I can save F_UDMI(f_shadow,ft_shadow,0) in the wall loop instead of the shadow wall loop*/

F_UDMI(f_shadow,ft_shadow,0)=function1;

}end_f_loop(f_w,ft_w)

...................

f_w and f_shadow denote wall face and its shadow face respectively.
