Conforming, non-conforming and non-matching discretization couplings in discrete fracture network simulations
Fumagalli, Alessio; Keilegavlen, Eirik; Scialo, Stefano (Peer reviewed; Journal article, 2019)Simulations of fluid flow in naturally fractured rocks have implications for several subsurface applications, including energy storage and extraction, and waste disposal. We are interested in flow in discrete fracture ... -
Dual virtual element methods for discrete fracture matrix models
Fumagalli, Alessio; Keilegavlen, Eirik (Peer reviewed; Journal article, 2019)The accurate description of fluid flow and transport in fractured porous media is of paramount importance to capture the macroscopic behavior of an oil reservoir, a geothermal system, or a CO2 sequestration site, to name ... -
Implementation of mixed-dimensional models for flow in fractured porous media
Keilegavlen, Eirik; Fumagalli, Alessio; Berge, Runar Lie; Stefansson, Ivar (Peer reviewed; Journal article, 2019)Models that involve coupled dynamics in a mixed-dimensional geometry are of increasing interest in several applications. Here, we describe the development of a simulation model for flow in fractured porous media, where the ... -
A multiscale flux basis for mortar mixed discretizations of reduced Darcy-Forchheimer fracture models
Ahmed, Elyes; Fumagalli, Alessio; Budisa, Ana (Peer reviewed; Journal article, 2019-05-27)In this paper, a multiscale flux basis algorithm is developed to efficiently solve a flow problem in fractured porous media. Here, we take into account a mixed-dimensional setting of the discrete fracture matrix model, ... -
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 ... -
Robust Linear Domain Decomposition Schemes for Reduced Nonlinear Fracture Flow Models
Ahmed, Elyes; Fumagalli, Alessio; Budisa, Ana; Keilegavlen, Eirik; Nordbotten, Jan Martin; Radu, Adrian Florin (Journal article; Peer reviewed, 2021)In this work, we consider compressible single-phase flow problems in a porous medium containing a fracture. In the fracture, a nonlinear pressure-velocity relation is prescribed. Using a non-overlapping domain decomposition ...
