Okay so from what I found out, since fluent solves density*diffusion, the units (kg/m3 * m2/s) result in kg/ms. So I suppose when you are defining diffusivity in the “materials” tab, you multiply your diffusivity with the fluid density.

My concern remains with the source term, will fluent automatically multiply density of the fluid or do I have to multiply is manually.
