Abstract : Aerodynamic analyses of weapon separation, missile launching and crew escape problems can be accomplished with the software package STORESIM. It is based on the numerical simulation of the systems of equations which govern fluid and rigid body dynamic motions. STORESIM represents a state of the art CFD capability for simulations of multiple, moving bodies. This capability is achieved through an integrated system of modules incorporating unstructured grid generation, finite element flow solution, six degree of freedom rigid-body motion, grid movement/restructuring and time dependent results visualization. Although the overall STORESIM package is tightly integrated and presents a uniform view of the simulation to the user, the individual modules may be used as standalone programs. This report describes each module in detail, as well as several validation and demonstration cases for typical separation environments consisting of regions of compressible, viscous flow.
