Diffusion modelling through porous media??
 

Hi,
I am new to Fluent. My probelm involves a modelling of diffusion of water vapours and oxygen through porous media (i.e Plastic films with pinholes). I have tried using speics transport model but couldn't solve it. Does anyone have any idea what should I do???? thanks

Hi,
you can also try UDS (user defined scalars).
