Fluid-structure interaction based upon a stabilized (ALE) finite element method

The computational procedure presented in this study is focussed on the time-dependent solution of two-dimensional coupled motions of geometrically nonlinear structures and viscous incompressible Newtonian fluids. For the fluid part a stabilized finite element method based upon an arbitrary Lagrangean-Eulerian (ALE) approach has been developed. For both the fluid and the structural systems direct time integration schemes, along with finite element spatial discretization, are employed. In order to enable large deformations of the flexible structures geometrically nonlinear effects are taken into account. The overall numerical model is treated as a three-field problem, including the moving mesh as an own system, and solved through partitioned procedures.
