Sensitivity Analysis for Design Optimization Integrated Software Tools, Phase I

Completed Technology Project

Project Introduction

The objective of this proposed project is to provide a new set of sensitivity analysis theory and codes, the Sensitivity Analysis for Design Optimization Integrated Software Tool set, to work within the existing NASA O3 Tool. In this Phase I effort, the sensitivity approach will be implemented for two basic types of analysis, namely static systems of equations (linear and non-linear) and eigen-problems. This implementation will focus on the elements most commonly used for aerospace design; beam, plate, and shell elements. The following specific goals are identified: 1 Integrated Multidisciplinary Sensitivity Analysis Toolset for Design Optimization (software) 2 Use of Advanced Algorithms to Maximize Computational Efficiency (analytic sensitivities) 3 Compatibility with Existing NASA Software Design Tools for computational integration to O3.
