Abstract:

This report presents an overview of an explicit message-passing paradigm for an 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 the Sun HPC 10000 computer system. The scalability of the message-passing code on this symmetrical multiple processor architecture is presented and is compared to the ideal linear multiple processor performance. The computed results are also compared to experimental data for the purpose of validating the shock physics application on the Sun HPC 10000 system.
