Generalized Multiscale Finite Element Methods for problems in perforated heterogeneous domains [PDF]

open access: yes, 2015
Complex processes in perforated domains occur in many real-world applications. These problems are typically characterized by physical processes in domains with multiple scales (see Figure 1 for the illustration of a perforated domain).

Crouzeix-Raviart MsFEM with Bubble Functions for Diffusion and Advection-Diffusion in Perforated Media [PDF]

open access: yes, 2015
International audienceThe adaptation of Crouzeix - Raviart finite element in the context of multiscale finite element method (MsFEM) is studied and implemented on diffusion and advection-diffusion problems in perforated media.

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.

Variational Multiscale error estimators for solid mechanics adaptive simulations: an Orthogonal Subgrid Scale approach [PDF]

open access: yes, 2016
In this work we present a general error estimator for the finite element solution of solid mechanics problems based on the Variational Multiscale method. The main idea is to consider a rich model for the subgrid scales as an error estimator.

Multiscale model construction and modulus prediction of needle-punched carbon/carbon composites

open access: yesPolymers and Polymer Composites, 2023
In this paper, the modulus prediction of NP-C/C is completed by establishing a multiscale finite element model, and the influence weight analysis of the modulus is carried out by using the analytical homogenization method.

Edge Multiscale Methods for elliptic problems with heterogeneous coefficients

open access: yes, 2018
In this paper, we proposed two new types of edge multiscale methods motivated by \cite{GL18} to solve Partial Differential Equations (PDEs) with high-contrast heterogeneous coefficients: Edge spectral multiscale Finte Element method (ESMsFEM) and Wavelet-

A convergence analysis of Generalized Multiscale Finite Element Methods [PDF]

open access: yesJournal of Computational Physics, 2019
In this paper, we consider an approximation method, and a novel general analysis, for second-order elliptic differential equations with heterogeneous multiscale coefficients. We obtain convergence of the Generalized Multi-scale Finite Element Method (GMsFEM) method that uses local eigenvectors in its construction.
