Stability analysis of a singlerate and multirate predictor-corrector scheme for overlapping grids

Ketan Mittal, Som Dutta, Paul Fischer

We use matrix stability analysis for a singlerate and multirate predictor-corrector scheme (PC) used to solve the incompressible Navier-Stokes equations (INSE) in overlapping grids…
