Chico Mbanu Guest Posts: n/a	Greetings I addition to my previous posting, I am also trying to model diffusion through two cylindrical tubings. I set the boundary conditions for the tubings as walls. Is it possible to give the diffusion coefficient for the tubings in the boundary conditions screen for walls (under species - zero net diffusive flux - mass fraction). Your help would be greatly appreciated. Chico
