Generalized Multiscale Finite Element Methods. Nonlinear Elliptic Equations [PDF]

open access: yesCommunications in Computational Physics, 2014
AbstractIn this paper we use the Generalized Multiscale Finite Element Method (GMsFEM) framework, introduced in [26], in order to solve nonlinear elliptic equations with high-contrast coefficients. The proposed solution method involves linearizing the equation so that coarse-grid quantities of previous solution iterates can be regarded as auxiliary ...

Multiscale Simulations for Coupled Flow and Transport Using the Generalized Multiscale Finite Element Method

open access: yesComputation, 2015
In this paper, we develop a mass conservative multiscale method for coupled flow and transport in heterogeneous porous media. We consider a coupled system consisting of a convection-dominated transport equation and a flow equation.

Generalized Multiscale Finite Element Methods with energy minimizing oversampling

open access: yesInternational Journal for Numerical Methods in Engineering, 2018
SummaryIn this paper, we propose a general concept for constructing multiscale basis functions within Generalized Multiscale Finite Element Method, which uses oversampling and stable decomposition. The oversampling refers to using larger regions in constructing multiscale basis functions and stable decomposition allows estimating the local errors.
