Optimized schwarz method

WebOver the last decade, optimized Schwarz methods have been developed for elliptic partial differential equations. These methods use more effective transmission conditions between subdomains,... WebRecently, Optimized Schwarz strategies have been proposed for the coupling of heterogeneous models, such as in Fluid-Structure Interaction problem (Gerardo-Giorda et al. (2010)) and in the coupling of Bidomain and Monodomain models in electrocardiology (Gerardo-Giorda et al. (2011)). The paper is organized as follow.

Web2 Optimized Restricted Additive Schwarz Methods Historically, domain decomposition methods were formulated at the continu-ous level. We consider a decomposition of the original domain Ω in (1) into two overlapping sub-domains Ω1 and Ω2, and we denote the interfaces by Γij = ∂Ωi ∩ Ωj, i 6= j, and the outer boundaries by ∂Ωj = ∂Ω ... The convergence speed depends on the size of the overlap between the subdomains, and on the transmission conditions (boundary conditions used in the interface between the subdomains). It is possible to increase the convergence speed of the Schwarz methods by choosing adapted transmission conditions: theses methods are then called Optimized Schwarz methods.
