water diffusion in membran

hallo,
i want to simulate waterdiffusion through a membran (porous). do anybody know how i can do it.

Do the CFX tutorials, both the ones which come with CFX and the ones on the CFX Community webpage (on the ANSYS webpage). Your simulation sounds pretty basic so try the tutorials first.

i ve get the simulation, but the problem ist the convergence of mass fraction.
i didnt get a convergence of the results.

Some further information about what you are doing might help......

i ve two canals. in the first canal flow gas (air) without humidity and in the second flow gas (air) with 100% humidity.
between the canals is a membran. I want to simulate the waterdiffusion from the second to the first canal.
