In these equations how can I access alpha(i,j) and Delta x and Delta y ?

alpha is volume fraction of the cell.

And what do you want to achieve?

This is just a part of the algorithm, it is used to develop an interface between two phases. The one Ansys uses (Youngs algorithm) is creating garbage values for some cases when the interface is complex (turbulent flows). Theoretically the algorithm I'm working on should be able to solve this problem, but unfortunately I'm not able to code for this in a UDF. I can code this if I develop the whole model myself but it'll take much longer and Ansys already provides a pretty accurate method to solve the remaining problem.

Thank you,

Gunjan
