An open-sourced multiscale solver is proposed to simulate two-phase flow in hybrid systems containing both solid-free regions and deformable porous matrices. This micro-continuum model is rooted in elementary physics and volume averaging principles, where a unique set of partial differential equations is used to represent flow in both regions and scales. The crux of the proposed model is that it tends asymptotically towards the Navier-Stokes volume-of-fluid approach in solid-free regions and towards multiphase Biot theory in porous regions. We showcase the model's flexibility through applications related to fracturing in porous media and wave dissipation in poroelastic coastal barriers.
