Abstract:
A flexible design study tool to couple optimization technology with third-party analysis programs is presented. The main objective of such a design study tool is to provide engineers with the necessary optimization tools so that optimization capabilities could be easily interfaced with analysis programs. This will provide the optimization capabilities where they do not exist. The basic architecture of the design study tool has been developed, and components are being added on an-ongoing basis. The architecture of this study tool is based on an object-relational database system, and object oriented programming methodology. Preliminary interfaces to the third-party software ABAQUS and LSDYNA3D have been developed, and similar interfaces to CAD/CAE packages are being considered. The development of such a study tool will provide the framework for developing multidiscipline design optimization (MDO) capabilities incorporating design information available from different disciplines of interest.
