A Finite-Volume-Based Module for Unsaturated Poroelasticity
Varela, Jhabriel; Gasda, Sarah Eileen; Keilegavlen, Eirik; Nordbotten, Jan Martin (Chapter, 2021)In this chapter, we present fv-unsat, a multipoint finite-volume–based solver for unsaturated flow in deformable and nondeformable porous media. The latter is described using the mixed form of Richards’ equation, whereas ... -
Flexible and rigorous numerical modelling of multiphysics processes in fractured porous media using PorePy
Stefansson, Ivar; Varela, Jhabriel; Keilegavlen, Eirik; Berre, Inga (Journal article; Peer reviewed, 2024)Multiphysics processes in fractured porous media is a research field of importance for several subsurface applications and has received considerable attention over the last decade. The dynamics are characterized by strong ... -
Implementation of an MPFA/MPSA-FV Solver for the Unsaturated Flow in Deformable Porous Media
Varela, Jhabriel (Master thesis, 2018-06-22)The Unsaturated Flow In Deformable Porous Media (UFIDPM) plays a crucial role in several academic and industrial applications such as; cracks induced by desiccation, collapsing soils, ground movement involving expansive ... -
PorePy: an open-source software for simulation of multiphysics processes in fractured porous media
Keilegavlen, Eirik; Berge, Runar Lie; Fumagalli, Alessio; Starnoni, Michele; Stefansson, Ivar; Varela, Jhabriel; Berre, Inga (Journal article; Peer reviewed, 2021)Development of models and dedicated numerical methods for dynamics in fractured rocks is an active research field, with research moving towards increasingly advanced process couplings and complex fracture networks. The ... -
A posteriori error estimates for hierarchical mixed-dimensional elliptic equations
Varela, Jhabriel; Ahmed, Elyes; Keilegavlen, Eirik; Nordbotten, Jan Martin; Radu, Adrian Florin (Journal article; Peer reviewed, 2022)Mixed-dimensional elliptic equations exhibiting a hierarchical structure are commonly used to model problems with high aspect ratio inclusions, such as flow in fractured porous media. We derive general abstract estimates ...
