【 摘 要 】

A monolithic semi-implicit method is presented for three-dimensional simulation of fluid−structure interaction problems. The updated Lagrangian framework is used for the structure modeled by linear elasticity equation and, for the fluid governed by the Navier−Stokes equations, we employ the Arbitrary Lagrangian Eulerian method. We use a global mesh for the fluid−structure domain where the fluid−structure interface is an interior boundary. The continuity of velocity at the interface is automatically satisfied by using globally continuous finite element for the velocity in the fluid−structure mesh. The method is fast because we solve only a linear system at each time step. Three-dimensional numerical tests are presented.
