Tri-axial test on a coal sample

Hi Nagi,

I'm trying to model permeability change and creep in a cylindrical coal sample under tri-axial stresses (Axial and confining), through which methane permeates from one circular end and exits from the other circular end. I included Poroelasticity physic to my modeling and then I incorporated solid mechanics in the physic to apply boundary conditions to the geometry. The problem is when I define Storage Model in my physic, it overrides Poroelastic Material as they are applied to the same domain. Could you help me solve this problem please? I have attached a file showing the geometry and boundary conditions.
Any help is kindly appreciated in advance.

Cheers,
Nima
