summations of variables in one row or column
 

Hi, All,

I am working on a source term using UDS in FLUENT. The source term is related to a summation of variables in one row and column as
S=(i-m)sum(\Deltax\cdot\U\cdot\scalar)_{j}/Vcell

The problem I have with this equation is how to fix j in y direction and summit the values in x direction from cell i to m?

Thanks for your suggestions,

lig
