This paper is concerned with an adapted version of AMLS for eigenfrequency analysis of fluid-solid interaction systems. Although fluid-solid vibrations are governed by an unsymmetric eigenproblem, the modified AMLS method needs approximately the same computational effort. An error bound related to the eigenvalue approximations is proved. © 2010 John Wiley & Sons, Ltd.en1099-150620113411427WileyAMLSAutomated multi-level sub-structuringEigenvalueFluid-solid interactionMathematicsJournal Article10.1002/nla.734Journal Article
