The HPCMP worked with the Naval Surface Warfare Center Indian Head Division to use the Dynamic System Mechanics Advanced Simulation (DYSMAS) tool to predict the detonation, tearing of the hull, and blast fields inside a ship and on its deck in the event of a topside attack.
In addition to underwater threats, naval vessels are subject to threats above the waterline. Topside detonations can create both external and internal blast fields if the hull rips open. Engineers must assess how well a ship can withstand the impact of detonations above the sea surface. With platforms limited and testing expensive, high-performance computing augments live-fire test results and provides insights earlier in the design process.
