Keywords: fluid-structure interaction, vibro-acoustic, coupled problem, non-matching grids, sub-structuring method, domain decomposition method, parallel computing.

This chapter presents sub-structuring and domain decomposition approaches to solve coupled fluid-structure problems with non-matching grids and illustrates the efficiency of these methods when applied to vibro-acoustic problems. The coupling is ensured through the boundary conditions defined along the fluid-structure interface. In contrast with the mortar finite element discretization, the coupled quantities are here integrated over a set of quadrature points defined on the fluid-structure interface. This approach only involves the computation of nodal values and interpolation at given Gauss points which allows any type of hp-refinement.
