Executive Summary

Our project focuses on developing, testing, and validating a novel software tool that will, for the first time, provide efficient simulation of three-dimensional, multifluid plasma interactions that occur in high-energy-density physics research and laboratory simulations of astrophysical shocks. This software tool will support mission-related research in high-energy-density science and inertial confinement fusion.
