Abstract
Due to the advancements made in computing technology during the past couple of decades, “Computational Design” has become a widely-used tool, enabling the engineers and scientists to design state-of-the-art technologies and configurations that can improve performance, reduce costs, and maximize energy efficiency, to name a few. In particular, for the aeromechanical and aero-thermo-elastic applications, the computational design relies heavily on the Computational Fluid Dynamics (CFD) and Computational Structural Dynamics (CSD) analyses. Therefore, extremely robust CFD/CSD simulation frameworks are required to drive and accelerate the design process. On the other hand, for high-fidelity optimization and design studies, it is useful to know the gradient (also called the sensitivity) of a set of global quantities with respect to many input design variables. The computed sensitivity information can then be used to step towards an optimum design that can achieve the desired objectives. In recent years, the “adjoint method” has gained a lot of traction and is being used for determining the sensitivity of an objective function to a set of design variables. Among many other areas, adjoint-based methods have been used in design and topology optimization, uncertainty quantification (UQ), validation and verification (V&V), error estimation, and adaptive mesh refinement. However, despite many years of development and advances made in adjoint techniques, there are still challenges that hinder their more widespread use due to significant effort needed for code development, cumbersome debugging process, large memory footprint, and high computational cost. In this talk, a set of enabling techniques for computational design are introduced that have advanced the state-of-the-art in CFD and design optimization. Such transformative leaps forward would greatly reduce the time and cost of computational design in many engineering applications.
