Generalized Multiscale Finite Element Method for piezoelectric problem in heterogeneous media

Engineering Analysis with Boundary Elements, 2022
Abstract In this paper, we study multiscale methods for piezocomposites. We consider a model of static piezoelectric problem that consists of deformation with respect to components of displacements and a function of electric potential. This problem includes the equilibrium equations, the quasi-electrostatic equation for dielectrics, and a system of ...

Adaptive Least-Squares Mixed Generalized Multiscale Finite Element Methods

Multiscale Modeling & Simulation, 2018
In this paper, we present two kinds of adaptive least-squares mixed generalized multiscale finite element methods (GMsFEMs) for solving an elliptic problem in highly heterogeneous porous media.

Multiscale Model Reduction with Generalized Multiscale Finite Element Methods in Geomathematics

2014
In this chapter, we discuss multiscale model reduction using Generalized Multiscale Finite Element Methods (GMsFEM) in a number of geomathematical applications. GMsFEM has been recently introduced (Efendiev et al. 2012) and applied to various problems.

A Generalized Multiscale Finite Element Method for Thermoelasticity Problems

2017
In this work, we consider the coupled systems of a partial differential equations, which arise in the modeling of thermoelasticity processes in heterogeneous domains. Heterogeneity of the properties requires a high resolution solve that adds many degrees of freedom that can be computationally costly.

A Generalized Finite Element Method for Multiscale Simulations

2012
Abstract : This report focuses on recent advances of the Generalized Finite Element Method (GFEM) for multiscale simulations. This method is based on the solution of interdependent global and local scale problems, and can be applied to a broad class of multiscale problems of relevance to the United States Air Force.
