Hi,everone I want to know how to identify the arrangement of cells or grids in FLUENT. I want to use this information to solve the differential equation by my source code. It is like using c(i+1,j)+c(i,j)+c(i-1,j)to discretize the differential equation. However, i don't know how to get the c(i+1,j),c(i,j)and c(i-1,j). All i can see in FLUENT is the pointer that points to cells and faces. I can not extract the cell identity and do some operation like i mentioned above. I need your help. Thanks.

HI, Could you explaina little bit more you source code ? Make sure you source code can be applied to unstructured mesh ? It means no possibility of (i,j) matrix consideration for cells arrangements.

Let me know if that helps you; cheers thomas

If your differential equation can be rewritten in the standard form supported by FLUENT for UDS, you had better to solve it this way.
