This presentation will describe the development of a design study tool to couple optimization technology with sophisticated analysis software graphical user interface. Primary objective has been to create a graphical user-interface (GUI) to the general purpose optimization software DOC/DOT, from V R&D, Inc. The second objective was to interface DOC/DOT with a number of third-party analysis software products to provide flexible optimization capabilities. DOC/DOT has already been interfaced with ABAQUS and other commercially available software, and the details of the developed capabilities will be discussed in this presentation.
