000013742 520__ $$2eng$$aThe ability to perform time-accurate simulation of coupled fluid-structure interaction in the presence of large fluid pressures and severe structural deformation is important to a large number of applications, such as structure-blast interactions and underwater explosions (UNDEX). The latter application in particular is a very challenging problem, because the deformation of the structure evolves on a time scale coincident with pressure variations in the fluid, thereby requiring a tight coupling at the fluid-structure interface. A detailed understanding of this problem is also critical to assessment of vulnerabilities in national infrastructure. The importance of this problem has been recognized for many years. The GEMINI suite of codes, developed and maintained by researchers at NSWC/IH [1], is a set of programs designed to simulate this problem; to predict damage and failure of structural components when subjected to underwater explosions. The explosive, air and water surrounding the vessel are modeled with the GEMINI Euler solver, while the deformation of the vessel is simulated with the structural dynamics code DYNA_N [2]. The fully coupled code is referred to as DYSMAS.
