multiple species diffusion

[sosat1012]

I am trying to simulate a multiple species diffusion. In a permeable (from the top) box that is surrounded by atmospheric air there is a source of CO2 and I want to find out the final concentrations of CO2, O2 and N2 inside the box (due to diffusion only not advection) when the system reaches equilibrium.

Is this possible? Does anyone know?

Seems like a problem CFX might be able to handle. You may want to post this same question to the CFD experts over at
