source actual mass transfer
hi, I'm modeling a flow with 2 species. i have defined several fluid zones as sink by setting a negativ mass source.
because my sinks are in a row right at the wall i get a boundary layer where the mass fraction of the species leaving through the sink gets 0.

Is it possible to report the actual mass fraction of the speacies leaving through the sinks. It is not equal to the amount set in the boundary conditions because the diffusion is not fast enough...

thanks for your help
