This report presents an overview of an explicit message-passing paradigm for a Eulerian finite-volume method for modeling solid dynamics problems involving shock wave propagation, multiple materials, and large deformations. Three-dimensional simulations of high-velocity impact were conducted on two scalable, high-performance computing systems to evaluate the performance of the message-passing code. Simulations were performed using 3 billion computational cells running on more than 8000 processor cores. The performance of the message-passing code was found to scale linearly on the two computer systems evaluated across the range of cases considered.
