A new staggered DG method for the Brinkman problem robust in the Darcy and Stokes limits
Lina Zhao, Eric Chung, Ming Fai Lam
In this paper we propose a novel staggered discontinuous Galerkin method for the Brinkman problem on general quadrilateral and polygonal meshes. The proposed method is robust in th…
Constraint Energy Minimizing Generalized Multiscale Discontinuous Galerkin Method
Siu Wun Cheung, Eric T. Chung, Wing Tat Leung
Numerical simulation of flow problems and wave propagation in heterogeneous media has important applications in many engineering areas. However, numerical solutions on the fine gri…
Space-Time Nonlinear Upscaling Framework Using Non-local Multi-continuum Approach
Wing T. Leung, Eric T. Chung, Yalchin Efendiev +2
In this paper, we develop a space-time upscaling framework that can be used for many challenging porous media applications without scale separation and high contrast. Our main focu…
Computational multiscale methods for first-order wave equation using mixed CEM-GMsFEM
Eric Chung, Sai-Mang Pun
In this paper, we consider a pressure-velocity formulation of the heterogeneous wave equation and employ the constraint energy minimizing generalized multiscale finite element meth…
A posteriori error estimates for the mortar staggered DG method
Lina Zhao, Eric Chung
Two residual-type error estimators for the mortar staggered discontinuous Galerkin discretizations of second order elliptic equations are developed. Both error estimators are prove…
Generalized Multiscale Finite Element Method for the poroelasticity problem in multicontinuum media
Aleksei Tyrylgin, Maria Vasilyeva, Denis Spiridonov +1
In this paper, we consider a poroelasticity problem in heterogeneous multicontinuum media that is widely used in simulations of the unconventional hydrocarbon reservoirs and geothe…
