Multiscale Partially Explicit Splitting with Mass Lumping for High-Contrast Wave Equations
Shu Fan Li, Wing Tat Leung
In this paper, contrast-independent partially explicit time discretization for wave equations in heterogeneous high-contrast media via mass lumping is concerned. By employing a mas…
