Elastic wave propagation in fractured media with spring-type and frictional contact deformation laws
Ingrid Kristine Jacobsen, Jan Martin Nordbotten, Ivar Stefansson +2
Elastic wave propagation in fractured media is relevant to applications such as analysis of seismic waves and non-destructive characterization of materials. Understanding attenuati…
A Finite Volume Method for Elastic Waves in Heterogeneous, Anisotropic and Fractured Media
Ingrid Kristine Jacobsen, Inga Berre, Jan Martin Nordbotten +1
Numerical modeling of elastic wave propagation in the subsurface requires applicability to heterogeneous, anisotropic and discontinuous media, as well as support of free surface bo…
A Line Search Algorithm for Multiphysics Problems with Fracture Deformation
Ivar Stefansson
Models for multiphysics problems often contain strong nonlinearities. Including fracture contact mechanics introduces discontinuities at the transition between open and closed or s…
Flexible and rigorous numerical modelling of multiphysics processes in fractured porous media using PorePy
Ivar Stefansson, Jhabriel Varela, Eirik Keilegavlen +1
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.…
Numerical modelling of convection-driven cooling, deformation and fracturing of thermo-poroelastic media
Ivar Stefansson, Eirik Keilegavlen, Sæunn Halldórsdóttir +1
Convection-driven cooling in porous media influences thermo-poro-mechanical stresses, thereby causing deformation. These processes are strongly influenced by the presence of fractu…
A fully coupled numerical model of thermo-hydro-mechanical processes and fracture contact mechanics in porous media
Ivar Stefansson, Inga Berre, Eirik Keilegavlen
A range of phenomena in the subsurface is characterised by the interplay between coupled thermal, hydraulic and mechanical processes and deforming structures such as fractures. Mod…
Verification benchmarks for single-phase flow in three-dimensional fractured porous media
Inga Berre, Wietse M. Boon, Bernd Flemisch +23
Flow in fractured porous media occurs in the earth's subsurface, in biological tissues, and in man-made materials. Fractures have a dominating influence on flow processes, and the…
Finite volume discretisation of fracture deformation in thermo-poroelastic media
Ivar Stefansson, Inga Berre, Eirik Keilegavlen
This paper presents a model where thermo-hydro-mechanical processes are coupled to a deformation model for preexisting fractures. The model is formulated within a discrete-fracture…
PorePy: An Open-Source Software for Simulation of Multiphysics Processes in Fractured Porous Media
Eirik Keilegavlen, Runar Berge, Alessio Fumagalli +4
Development of models and dedicated numerical methods for dynamics in fractured rocks is an active research field, with research moving towards increasingly advanced process coupli…
Call for participation: Verification benchmarks for single-phase flow in three-dimensional fractured porous media
Inga Berre, Wietse Boon, Bernd Flemisch +6
This call for participation proposes four benchmark tests to verify and compare numerical schemes to solve single-phase flow in fractured porous media. With this, the two-dimension…
Hybrid-Dimensional Finite Volume Discretizations for Fractured Porous Media
Ivar Stefansson, Inga Berre, Eirik Keilegavlen
Over the last decade, finite volume discretizations for flow in porous media have been extended to handle situations where fractures dominate the flow. These discretizations have s…
Benchmarks for single-phase flow in fractured porous media
Bernd Flemisch, Inga Berre, Wietse Boon +5
This paper presents several test cases intended to be benchmarks for numerical schemes for single-phase fluid flow in fractured porous media. A number of solution strategies are co…
