In recent years a great deal of advances have been made with respect to Dirichlet-Neuman (DN) partitioned fluid-structure interaction (FSI) solvers. Problems of varying degrees of complexity can be solved with reasonable efficiencies through the use of the various interface coupling techniques. One particular class of problems which however cannot be solved is fully enclosed FSI problems for incompressible fluids (eg. balloon inflation problems). In this paper we explore the use of partitioned FSI using artificial compressibility (AC), whereby the fluid equations are modified to allow for compressibility which internally incorporates an approximation of the system volume change as a function of pressure.
