I want to know what's the equivalent of the parameter (L=I+NI((J-1)+NJ(K-1)) in THE VERSION 6 of fluent..

Fluent 4 used a large 1-dimensional array, where L was the index, to store all cell data. Fluent 6 uses a cell and a thread notation. Fluent 4 used a structured grid and 6 is unstructured. As you are probably well aware of, if you are thinking of porting any code from Fluent 4 to Fluent 6, then the cell structure will only be a very small part of your concerns.

usually I use the version 4 of fluent, but now I'm forced to migrate to version 6 and I struggled to adapt to the new version of the UDF.
My goal is to inject a source terms in the cells (mesh) defined my area of computing. In version 4 this parameter is called L = I+NI ((J-1) + NJ (K-1)), for example if I want to inject a source term in the mesh number 50 just I put IF (L . EQ.50) THEN
ATERME = 1000
and so on.. but I do not know how do it in the version 6, for example if I want to inject a source term energy 1000w/m3 in the mesh number 50??

Thanks for your help
