A multiplicative Schwarz method and its application to nonlinear acoustic-structure interaction
ESAIM: Modélisation mathématique et analyse numérique, Tome 43 (2009) no. 3, pp. 487-506

A new Schwarz method for nonlinear systems is presented, constituting the multiplicative variant of a straightforward additive scheme. Local convergence can be guaranteed under suitable assumptions. The scheme is applied to nonlinear acoustic-structure interaction problems. Numerical examples validate the theoretical results. Further improvements are discussed by means of introducing overlapping subdomains and employing an inexact strategy for the local solvers.
