Ah..., Hi everyone,

I've checked the "c1" thread's ID by usnig THREAD_ID(t1) , which returns the cell zone value of porous, where 

t1 = THREAD_T1(t);
 
and t is the thread of the face boundary. This indicates that "c0' and "c1" in the above picture is upside down, and Fluent take cell adjacent to fluid zone as "c0" in this case.

The other question about c1 is there is no value in "c1" cell when I called cell or face macro,which ends to  SIGSEGV, altough THREAD_ID(t1) do return value.

Looking forward any help

Thanks!
