Abstract

This paper is concerned with some of the major issues which have been addressed in the implementation of Arbitrary Lagrangian-Eulerian (ALE) finite element methods for transient fluid-structure problems. We first recall the basic concepts underlying the ALE kinematical description and present an automatic algorithm for assigning grid velocities and thereby provide the ALE finite element code with a continuous rezoning capability. Emphasis is then placed on time integration of the semi-discrete ALE conservation equations for mass, momentum and energy, on the incorporation of shock-capturing techniques in the ALE finite element context and on ALE stress update algorithms for materials exhibiting path-dependent constitutive behaviour.
