Prediction of Discretization of GMsFEM using Deep Learning
Min Wang, Siu Wun Cheung, Eric T. Chung +3
In this paper, we propose a deep-learning-based approach to a class of multiscale problems. THe Generalized Multiscale Finite Element Method (GMsFEM) has been proven successful as…
Nonlinear nonlocal multicontinua upscaling framework and its applications
Wing T. Leung, Eric T. Chung, Yalchin Efendiev +1
In this paper, we discuss multiscale methods for nonlinear problems. The main idea of these approaches is to use local constraints and solve problems in oversampled regions for con…
Multiscale stabilization for convection diffusion equations with heterogeneous velocity and diffusion coefficients
Eric T. Chung, Yalchin Efendiev, Wing Tat Leung
We present a new stabilization technique for multiscale convection diffusion problems. Stabilization for these problems has been a challenging task, especially for the case with hi…
Constraint Energy Minimizing Generalized Multiscale Finite Element Method for dual continuum model
Siu Wun Cheung, Eric T. Chung, Yalchin Efendiev +2
The dual continuum model serves as a powerful tool in the modeling of subsurface applications. It allows a systematic coupling of various components of the solutions. The system is…
Upscaling method for problems in perforated domains with non-homogeneous boundary conditions on perforations using Non-Local Multi-Continuum method (NLMC)
Maria Vasilyeva, Eric T. Chung, Wing Tat Leung +2
In this paper, we present an upscaling method for problems in perforated domains with non-homogeneous boundary conditions on perforations. Our methodology is based on the recently…
Nonlocal multicontinuum (NLMC) upscaling of mixed dimensional coupled flow problem for embedded and discrete fracture models
Maria Vasilyeva, Eric T. Chung, Wing Tat Leung +1
In this work, we present an upscaled model for mixed dimensional coupled flow problem in fractured porous media. We consider both embedded and discrete fracture models (EFM and DFM…
Multiscale Methods for Model Order Reduction of Non Linear Multiphase Flow Problems
Gurpreet Singh, Wingtat Leung, Mary F. Wheeler
Numerical simulations for flow and transport in subsurface porous media often prove computationally prohibitive due to property data availability at multiple spatial scales that ca…
