Fluid-structure interaction problems arise in many fields of application such as flows around elastic structures or blood flow in arteries. The method presented in this paper for solving such a problem is based on a reduction to an equation at the interface, involving the so-called Steklov-Poincaré operators. This interface equation is solved by a Newton… (More)

In this paper, we present some analysis and numerical studies on two partitioned fluid-structure interaction solvers: a preconditioned GMRES solver and a Newton based solver, for the fluid-structure interaction problems employing a nearly incompressible elasticity model in a classical mixed displacement-pressure formulation. Both are highly relying on… (More)

In this work, we propose a preconditioned GMRES solver for a Schur complement equation of the linearized fluid-structure interaction problem, with respect to the displacement unknowns only on the interface. The preconditioning for the Schur complement equation requires approximate solutions of the fluid and structure sub-problems with appropriate boundary… (More)

Flight rerouting is an important strategy in the airspace with the limit of heavy weather and flight conflict. First, the grid method was utilized to build the model for diverting airspace environment based on numerical weather prediction features in severe weather. In considering the air traffic rules and aircraft performance, a new rerouting path planning… (More)

In this work, a two-layer coupled fluid-structure-structure interaction model is considered, which incorporates an anisotropic structure model into the fluid-structure interaction problems. We propose two domain decomposition solvers for such a class of coupled problems: a Robin-Robin preconditioned GMRES solver combined with an inner Dirichlet-Neumann… (More)

In this work, the robustness of the fluid-structure interaction simulation with a nearly incompressible elasticity model from our previous work [Partitioned solvers for the fluid-structure interaction problems with a nearly incompressible elasticity model, Comput Visual Sci, 14:227-247, 2012] is improved. At each time step of the FSI simulation, using… (More)
