A two-grid preconditioner with an adaptive coarse space for flow simulations in highly heterogeneous media
Yanfang Yang, Shubin Fu, Eric T. Chung
In this paper, we consider flow simulation in highly heterogeneous media that has many practical applications in industry. To enhance mass conservation, we write the elliptic probl…
Online mixed multiscale finite element method with oversampling and its applications
Yanfang Yang, Shubin Fu, Eric T Chung
In this paper, we consider an online basis enrichment mixed generalized multiscale method with oversampling, for solving flow problems in highly heterogeneous porous media. This is…
Residual driven online mortar mixed finite element methods and applications
Yanfang Yang, Eric T. Chung, Shubin Fu
In this paper, we develop an online basis enrichment method with the mortar mixed finite element method, using the oversampling technique, to solve for flow problems in highly hete…
An enriched multiscale mortar space for high contrast flow problems
Eric T. Chung, Shubin Fu, Yanfang Yang
Mortar methods are widely used techniques for discretizations of partial differential equations and preconditioners for the algebraic systems resulting from the discretizations. Fo…
