Abstract

This paper gives an overview on our recent research activities on a fixed grid fluid-structure interaction scheme that can be applied to the interaction of most general structures with incompressible flow. The developed approach is based on an eXtended Finite Element Method (XFEM) based strategy to allow moving interfaces on fixed Eulerian fluid grids. The enriched Eulerian fluid field and the Lagrangian structural field are partitioned and iteratively coupled using Lagrange multiplier techniques for non-matching grids. The approach allows the simulation of the interaction of thin and bulky structures exhibiting large deformations. Extensions towards automatic adaptivity and fluid boundary layer meshes are sketched and the principle applicability to contact simulations of submerged structures are presented.
