A SYSTEMS APPROACH TO CFD CODE DEVELOPMENT

Keywords: cfd, systems approach

We discuss the idea of developing a CFD code using a systems integration approach. The approach considers identification of intended applications, determination of functional requirements, system architecture, selection/development of components, and trades of component technology. This is in contrast to the approach of connecting research components into an engineering code. This systems approach is illustrated by the successful transonic cruise design and analysis code, TRANAIR. We then identify Navier-Stokes analysis for separated flows as the key capability to support providing aerodynamic data base in an airplane development process. This new challenge requires further algorithm research. The necessary algorithm advancements are discussed.
