PEGSUS 4.0 User's Manual

Abstract

Many aerodynamic configurations are too complex to be represented by a single computational mesh. A multiple-mesh domain decomposition method called chimera has been developed to allow complex aerodynamic configurations to be modeled by a system of individually generated meshes, each representing a component of the overall configuration. The chimera approach requires the use of two computer codes, PEGSUS and a flow solver. PEGSUS calculates the interactions among the meshes and produces a file consisting of interpolation information that is used by the flow solver to obtain a global flow-field solution for the entire mesh system. This report documents the design and use of the latest version (4.0) of PEGSUS, and describes techniques for proper modeling of complex aerodynamic configurations.
