dc.description.abstractThis work presents a non symmetric Finite-Boundary Element Tearing and Interconnecting (FE-BETI) formulation for acoustic FSI problems, where the finite element method is used to model the structure, while the acoustical fluid domain is represented by the boundary element method. The method interconnects fluid and structure domains using the localized Lagrange multipliers, allowing the use of non-matching meshes on the interfaces. Furthermore, the methodology proposes a preconditioned projected biconjugate gradient solver, that presents good scalability properties in the solution of large problems.
