Abstract

This paper presents an approach to shape optimization that integrates the tasks of geometric modeling, design parameterization, design characterization, response analysis, sensitivity analysis, and optimization. The developed approach integrates the response analysis, sensitivity calculation and optimization around the modeling code. All data preparation and post- processing tasks can be performed from within modeling software. To interface with commercially available software packages, several techniques for using existing functions have been developed. Other desired functions have been added using command language functions, menu customization features and external codes. An overview of the shape optimization process is given with some design examples, in order to demonstrate the ease and efficiency of the developed approa
