The ability to model the different regimes of a physical event using different numerical techniques has a number of advantages. Instead of applying the same general solver to all domains of a problem, a solver optomized for a particular regime of material behavior may be used. Thus, in a single analysis, one type of solver may be used for fluid behavior while another type is used for solid/structural response. The various domains in the problem are then coupled together in space and time to provide an efficient and accurate solution. Examples in the use of Eularian, Lagrangian, Arbitrary Langrange Eulerian (ALE), Structural, and Smooth Partcle Hydrodynamics (SPH) techniques, in various combinations, will be applied to general problems in flui-structure interaction and impact problems. The relative advantages and limitations of such coupled approaches will be discussed.
