An algebraic multiscale preconditioner for large sparse SPD matrices

Yingjie Zhou, Shubin Fu, Eric Tsz Shun Chung

We present a two-grid algebraic multiscale preconditioner for large sparse symmetric positive definite systems arising from elliptic problems with highly heterogeneous coefficients…

Graph-Based Meshfree Multi-scale Coarse Space Approximation for Two-Level Schwarz Methods

Yucheng Liu, Tak Shing Au Yeung, Eric T. Chung +1

Efficient simulation of Darcy flow in highly heterogeneous porous media requires iterative solvers that remain robust under large permeability contrasts and mixed boundary conditio…
