An Integration Framework for Simulations of Solid Rocket Motors

Abstract

Simulation of solid rocket motors requires coupling physical models and software tools from multiple disciplines, and in turn demands advanced techniques to integrate independently developed physics solvers e ectively. In this paper, we overview some computer science components required for such integration. We package these components into a software framework that provides system support of high-level data management and performance monitoring, as well as computational services such as novel and robust algorithms for tracking Lagrangian surface meshes, parallel mesh optimization, and data transfer between nonmatching meshes. From these reusable framework components we construct domain-speci c building blocks to facilitate integration of parallel, multiphysics simulations from high-level speci cations. Through examples, we demonstrate the exibility of our framework and its components.
