Concurrent optimization of mesh refinement and design parameters in multidisciplinary design

accuracy in terms of discretization error. Further discussed are the challenges that a design-optimization setting poses to the estimation of discretization error and how the ‘optimum’ mesh-refinement assessment is, in fact, nested within the design-optimization problem. The paper puts forth two significant contributions for multidisciplinary design-optimization formulations: 1) investigation of the impact of the so-called design inputs to discretization error in multidisciplinary design optimization, and 2) development of a concurrent optimization framework for simultaneous mesh refinement and design parameter optimization for multidisciplinary systems. The proposed method is illustrated using a simplified aircraft wing-design problem. I. Introduction I
