Optimized schwarz method
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. WebAbstract Optimized Schwarz methods (OSMs) use Robin transmission conditions across the subdomain interfaces. The Robin parameter can then be optimized to obtain the fastest convergence. A new formulation is presented with a coarse grid correction.
