Moving porous matrix in Two-phase Darcy's law

I am modeling two-phase flow in porous material. What I want to see as a result is the interface between the two fluids and the pressure. For now I have been using Laminar Two-phase Flow mechanics with phase field method to show the interface between the fluids. I haven't added the porous matrix yet. The problem is that my porous matrix has to move in "y" direction. I tried to model that as a volume force but I am not sure how accurate it is.
My question is - Can I reduce the Navier-stokes equations to Darcy's law in the Coefficient form PDE interface and represent the moving porous matrix as just a volume force? Or can I model this using the Two-phase Darcy's law interface? And then the question is how to model the moving porous matrix.
Thank you in advance

I'm also trying to simulate a two-phase flow. Can you give me a clue on the boundary setting? What kind of boundary do you use for saturation?
