Simulations of hypervelocity impact problems are performed frequently by government laboratories and contractors for armor/anti-armor applications. These simulations need to deal with shock wave physics phenomena, large material deformation, motion of debris particles and complex geometries. As a result, memory and processing time requirements are large for detailed, three-dimensional calculations. The large massively parallel supercomputing systems of the future will provide the power necessary to greatly reduce simulation times currently required by shared-memory, vector supercomputers. This paper gives an introduction to PCTH, a next-generation shock wave physics code which is being built at Sandia National Laboratories for massively parallel supercomputers, and demonstrates that massively parallel hydrocodes, such as PCTH, can provide highly-detailed, three-dimensional simulations of armor/anti-armor systems.
