Abstract
This report describes a methodology for completing simulations of flow around a standard bare submarine hull using CFX-5. The simple case of zero yaw is used to demonstrate the process used to set up, run and analyze a simulation. The process of creating the geometry, mesh generation, boundary condition application, solution control and post processing is described. Particular emphasis is placed on building a high quality unstructured mesh for resolving boundary layer flows. Subsequently images of the mesh and results are shown to further the understanding of how to model a domain effectively and efficiently. Efforts to ensure a mesh insensitive solution are shown. Final values are validated against wind tunnel testing.
