A robust VEM-based approach for flow simulations in poro-fractured media

In this paper, a Virtual Element Method (VEM)-based approach is proposed for the simulation of flow in fractured porous media. The method is based on a robust meshing strategy, capable of producing conforming polyhedral meshes of intricate geometries and relies on the robustness of the VEM in handling distorted and elongated elements. Numerical tests in challenging configurations are presented and discussed, also in a time-dependent setting to show the viability and the effectiveness of the method.
