Arbitrary Lagrangian Eulerian (ALE) ®nite element methods gain interest for the capability to control mesh geometry independently from material geometry. In ¯uid±structure interaction problems, where the ¯uid mesh near the structure undergoes large deformations and becomes unacceptably distorded, wh

In this work we describe and compare two monolithic models for fluid-structure interaction problems: First, the well-established ALE model using natural Lagrangian coordinates for the structural model and using an artificial coordinate system for the flow problem. Then, a novel approach, the fully E
## Abstract A numerical method, which relaxes limitation of small time increment in fluid–structure interaction (FSI) simulations with hard solid, is developed based on a full Eulerian FSI model (Sugiyama __et al__. __Comput. Mech.__ 2010; **46**(1):147–157). In this model, the solid volume fractio
