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, ...
