Imposing pressure and velocity continue boundary conditions

I am building a model to understand fluid flow inside a porous medium. I have a thin film on liquid which is being absorbed into the porous medium. The liquid film is a free boundary and flows by laminar flow. I enabled the porous medium flow in the porous block and nothing the film section. The inlet velocity is specified for the film and the outlet pressure=0. the initial condition is the same for both regimes.
I want to specify pressure continuity and velocity continuity conditions at the boundary between the fluid film and porous medium. I tried to impose them using interior fan and interior walls conditions in laminar flow physics but it did not work.
Can you please suggest how I can impose these boundary conditions?
Thank you
Shreya
