UDF for C_UDMI(c,t,0)=T(i,j,k)-T(i+10,j,k)
 

Hi, I am working with Ansys/Fluent 12.1, I am going to define a UDF as shown above, but the data of Fluent is define as T(c,t), I don't know how to bring T(c,t) from different postion in to one cell. Although I can modify the T(i+10,j,k) by loop macros, how can I take it into C_UDMI(c,t,0) without changing it cell c and thread t into the data of T(i,j,k). Look forward to your attention and Thanks a lot.
