Computational Multiscale Methods for Linear Poroelasticity with High Contrast
Shubin Fu, Robert Altmann, Eric T. Chung +3
In this work, we employ the Constraint Energy Minimizing Generalized Multiscale Finite Element Method (CEM-GMsFEM) to solve the problem of linear heterogeneous poroelasticity with…
Online basis construction for goal-oriented adaptivity in the Generalized Multiscale Finite Element Method
Eric T. Chung, Sara Pollock, Sai-Mang Pun
In this research, we develop an online enrichment framework for goal-oriented adaptivity within the generalized multiscale finite element method for flow problems in heterogeneous…
An adaptive dynamically low-dimensional approximation method for multiscale stochastic diffusion equations
Eric T. Chung, Sai-Mang Pun, Zhiwen Zhang
In this paper, we propose a dynamically low-dimensional approximation method to solve a class of time-dependent multiscale stochastic diffusion equations. A dynamically bi-orthogon…
Online adaptive basis enrichment for mixed CEM-GMsFEM
Eric T. Chung, Sai-Mang Pun
In this research, an online basis enrichment strategy for the constraint energy minimizing generalized multiscale finite element method in mixed formulation is proposed. The online…
Computational multiscale methods for linear heterogeneous poroelasticity
Robert Altmann, Eric Chung, Roland Maier +2
We consider a strongly heterogeneous medium saturated by an incompressible viscous fluid as it appears in geomechanical modeling. This poroelasticity problem suffers from rapidly o…
