Stabilized Multiscale Nonconforming Finite Element Method for the Stationary Navier-Stokes Equations

open access: yesAbstract and Applied Analysis, 2012
We consider a stabilized multiscale nonconforming finite element method for the two-dimensional stationary incompressible Navier-Stokes problem. This method is based on the enrichment of the standard polynomial space for the velocity component with ...

Randomized Oversampling for Generalized Multiscale Finite Element Methods [PDF]

open access: yesMultiscale Modeling & Simulation, 2016
In this paper, we study the development of efficient multiscale methods for flows in heterogeneous media. Our approach uses the Generalized Multiscale Finite Element (GMsFEM) framework. The main idea of GMsFEM is to approximate the solution space locally using a few multiscale basis functions.

Multiscale Model Reduction of the Unsaturated Flow Problem in Heterogeneous Porous Media with Rough Surface Topography

open access: yesMathematics, 2020
In this paper, we consider unsaturated filtration in heterogeneous porous media with rough surface topography. The surface topography plays an important role in determining the flow process and includes multiscale features.

Residual-driven online generalized multiscale finite element methods [PDF]

open access: yesJournal of Computational Physics, 2015
The construction of local reduced-order models via multiscale basis functions has been an area of active research. In this paper, we propose online multiscale basis functions which are constructed using the offline space and the current residual. Online multiscale basis functions are constructed adaptively in some selected regions based on our error ...

High-resolution multiscale modeling of mechanical behavior of cold-drawn pearlitic steels

open access: yesJournal of Materials Research and Technology, 2021
A strategy based on representative volume element (RVE) was proposed to investigate the mechanical behavior of cold-drawn pearlitic steels at multiscale. Firstly, a finite element model based on macroscale was used to simulate the cold drawing.

A Multiscale Mortar Mixed Finite Element Method [PDF]

open access: yesMultiscale Modeling & Simulation, 2007
We develop multiscale mortar mixed finite element discretizations for second order elliptic equations. The continuity of flux is imposed via a mortar finite element space on a coarse grid scale, while the equations in the coarse elements (or subdomains) are discretized on a fine grid scale.

Multiscale Multiphysics Modeling of the Infiltration Process in the Permafrost

open access: yesMathematics, 2021
In this work, we design a multiscale simulation method based on the Generalized Multiscale Finite Element Method (GMsFEM) for numerical modeling of fluid seepage under permafrost condition in heterogeneous soils.

Multiscale modeling of magnetic distribution of ribbon magnetic cores

open access: yesCES Transactions on Electrical Machines and Systems, 2018
The multiscale finite element method (MsFEM) combined with conventional finite element method (CFEM) is proposed to solve static magnetic field in the ribbon magnetic core with non-periodical corners considered.
