WebSep 15, 2024 · In this work, a non-overlapping Schwarz method is constructed with the unsteady simulation of de-icing as the targeted application. To do so, optimized coupling coefficients are first derived for the one dimensional unsteady heat equation with linear boundary conditions and for the steady heat equation with non-linear boundary conditions.
Webthe optimized Schwarz methods on the optimal control problem is still open. Of course, other domain decomposition methods are also applicable, see for example [28] for FETI-DP methods; [26,27] for balancing Neumann–Neumann methods. For other type of domain decompositions and other type of governing equations, we refer the reader to [31].
