But the unity in Fluent are kg.m^-3.s^-1 I awnt to know if i have to divide my Flux by a volume and if yes, by what volume? The volume of a cell or the volume of my system? And an other question. When fluent will injection my mass. If for exemple I have a constant injection of 1000kg.s^-1. For 1 cell it will inject 1000 * (cell volume) * (time step)? or something else? Please help me Thank you
