Direction vectors:

I am a new user.
Please I am having challenge in specifying the direction vectors for the porous zones which i created for a cylindrical column with two fluid zones. The lower zone is my porous zone. I am not sure on how to specify the coordinate for the direction vectors 1 and 2. More so I couldn't update correctly from the plane tool options. Please Help!


Adsorption in the porous zone:

I also want the fluid flowing through the porous zone to adsorb some species from the porous media. Please I need insight on how to specify the species mixtures and the adsorption process.
