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.
A graphical user interface for the existing DOC software has been developed. This
provides a useful tool for developing and testing new ideas as well as creating a user-friendly
interface to the DOC software. Different GUI objects are used to generate project information
consisting of a catalog of variables and responses, design variables, objective function(s), design
constraint(s) and other problem parameters.
A catalog of variables and responses to be used in the optimization process is created first.
The basic idea is to identify all the input and output parameters that will be used during
optimization, and include them in the project catalog. From this project catalog, user can create
multiple "task files" to solve particular design optimization problems. The project catalog
information will be created only once, and could be used and accessed by one or more users to
create their particular optimization task.
When the design variable window is opened, the user sees only those entries in the catalog
that were identified as inputs, because these are the parameters that can be changed during
optimization. Here the user specifies the variable(s) to be used during optimization, prov
