How to obtain diffusion flux
Hi experts

I want to obtain diffusion flux in kg/s at a interface between two cell types. My scalar species are SF6 and air. I am ablbe to obtain mass fraction Yi stored in cells. By fick's law, diffusion flux should be Summation (Yi+1-Yi)*density*D*Ai/(Xi+1-Xi)

where D is molecular diffusitiy, and Ai is area of cell i

It is hard to locate corresponding cell number value of two cell type at interface. Would you plaese advise any suggestion to slove my question? Thank you in advance.
