Optimized Schwarz methods for the time-dependent Stokes-Darcy coupling

journal contribution
posted on 2023-06-22, 10:16 authored by Marco DiscacciatiMarco Discacciati, Tommaso Vanzan

This paper derives optimized coefficients for optimized Schwarz iterations for the time-dependent Stokes–Darcy problem using an innovative strategy to solve a nonstandard min-max problem. The coefficients take into account both physical and discretization parameters that characterize the coupled problem, and they guarantee the robustness of the associated domain decomposition method. Numerical results validate the proposed approach in several test cases with physically relevant parameters.
