PEGSUS 3.0 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 XMER3D. PEGSUS calculated the interactions between 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 of PEGSUS and describes techniques for the proper modeling of complex aerodynamic configurations.
