Resum
This paper presents advancements toward a monolithic solution procedure and anisotropic mesh adaptation for the numerical solution of fluidstructure interaction with complex geometry. First, a new stabilized three-field stress, velocity, and pressure finite element formulation is presented for modeling the interaction between the fluid (laminar or turbulent) and the rigid body. The presence of the structure will be taken into account by means of an extra stress in the NavierStokes equations. The...
