In order to solve structural problems submitted to a fluid-induced loading, we are interested in solving a fluid-structure interaction problem involving a deforming solid and a viscous fluid, under incompressible flow. We propose to use a partitioned but strongly coupled Gauss-Seidel scheme. We propose to solve the fluid part of the simulation by a finite element method with a scalable mixed domain decomposition strategy. A fictitious domain method enables taking into account the fluid-structure interface inside each fluid subdomain. Here, we describe the domain decomposition method and the coupling process on a stationary problem.
