The goal of this paper is to test solids4Foam, the fluid-structureinteraction (FSI) toolbox developed for foam-extend (a branch of OpenFOAM), andassess its flexibility in handling more complex flows. For this purpose, weconsider the interaction of an incompressible fluid described by a Leray modelwith a hyperelastic structure modeled as a Saint Venant-Kirchhoff material. Wefocus on a strongly coupled, partitioned fluid-structure interaction (FSI)solver in a finite volume environment, combined with an arbitraryLagrangian-Eulerian approach to deal with the motion of the fluid domain. Forthe implementation of the Leray model, which features a nonlinear differentiallow-pass filter, we adopt a three-step algorithm called Evolve-Filter-Relax. Wevalidate our approach against numerical data available in the literature forthe 3D cross flow past a cantilever beam at Reynolds number 100 and 400.
