Hello, all. I am new to CFD and fluent software. Can anyone help me with the problems?

I try to solve this multi-phase, porous media problem. I draw 3 domains (2 fluids [in and out] and a fluid-porous in the middle), because I want to know the fluids situation in that porous media as well. The fluid goes in from the left and seeped through the porous media, and then goes out from the right.
Fluent automatic define those two lines (red arrows) as ‘wall’ which means the flow is blocked in the section 1. To allow the flow goes through the porous media, what boundary conditions I shall use for porous media surface?
I am sorry if I asked a silly question.

I guess I found a solution, at least the flow is not blocked in the inlet section. Thanks to the ppl
