 The structural mechanics problem is solved using a FE structured mesh conformed by around 3.3k linear quadrilateral elements implementing a Total Lagrangian formulation. On the other hand, the fluid dynamics problem is solved using a FE unstructured mesh of around 30k linear triangular elements implementing an ALE ASGS Navier-Stokes formulation. The obtained fluid velocity and structure displacement fields, together with the deformed geometry, are shown below. The obtained results are in agreement to the ones in the reference publication.
