I am a student, I am doing a 3D simulation where there is a cilinder, where the Laminar flow physics is selected, and in the surrouding a block that it's a poroelastic medium ( I used the solid mechanics and darcy's law module since I do not have the poroelastic module interface), I have got a problem because the fluid must flow from the cubic block(poroelastic medium) through the cylinder (laminar flow), but it doesn't happen.
The boundary condition imposed are:
-Costant Pressure in the outer surfaces of the block
-Outlet pressure in one the edges of the cylinder
-fixed constraint in the outer surfaces of the block
- leaking wall in the laminar domain
I have noticed that in the darcy domain the no flow condition is imposed in the interfaces where the fluid must flow from the porous medium to the cylinder.
How can I resolve the problem?
thank you for the potential answer
