A Two-Level Preconditioner Based on Dominant Components for Time-Dependent Multiscale High-Contrast Problem
In this work, we develop a two-level overlapping preconditioner for time-dependent problems in high-contrast multiscale media. We present a coarse-space construction based on multiscale methods, with emphasis on the relaxed nonlocal multicontinuum (NLMC) method. The NLMC space can be separated into
