Dear friends

I'm trying to simulate solid particles dissolution using VOF method. For this, I need to know the coordination of each phase cell center. I mean for the cells that have 0<alfa<1 (alfa is solid volume fraction),I have to know the coordinate of each phase center within the cell. Please see attached picture. I need to calculate ds (distance between interface center and phase 2 center).

I would be so much appreciated if somebody can introduce me some references regarding the method which FLUENT applys for calculation of face fluxes in VOF method.
