Abstract

Adjoint based shape optimization methods have proven to be computationally efficient for aerodynamic problems. The majority of the studies on adjoint methods have used structured grids to discretize the computational domain. Due to the potential advantages of unstructured grids for complex configurations, in this study we have developed and validated a continuous adjoint formulation for unstructured grids. Initial results from this study was presented at the summer AIAA conference at Orlando in June, 2003. We have since tested the computational methodology on a few other aircraft configurations and also initiated a CAD based geometry handling process to support single and multidisciplinary analysis and design.
