Global existence of weak solutions to unsaturated poroelasticity
Both, Jakub Wiktor; Pop, Iuliu Sorin; Yotov, Ivan (Journal article; Peer reviewed, 2021)We study unsaturated poroelasticity, i.e., coupled hydro-mechanical processes in variably saturated porous media, here modeled by a non-linear extension of Biot’s well-known quasi-static consolidation model. The coupled ... -
Robust Discretization of Flow in Fractured Porous Media
Boon, Wietse; Nordbotten, Jan Martin; Yotov, Ivan (Peer reviewed; Journal article, 2018)Flow in fractured porous media represents a challenge for discretization methods due to the disparate scales and complex geometry. Herein we propose a new discretization, based on the mixed finite element method and mortar ...
