Specifically at NASA we see direct application in the efficient integration into the optimization environment of analysis modules already built in the Object-Oriented Optimization Tool. At the conclusion of Phase I we see immediate benefit to optimizing for Weight or to determine sizing and shape for structural members of aircraft. Mechanical Deflection, Stress, and Strain analysis, and Buckling analysis codes will also benefit. Frequency and Mode Shape analysis and others future modules can then provide first order sensitivity. This information can then be fed directly to the optimizer or to an approximation concepts approach. Having standalone sensitivity modules will also provide NASA flexibility in evaluating constraints and responses not necessarily available in standard commercial codes.
Sensitivity analysis is required for efficient optimal design and reliability analysis. Optimization is today widely used in the aerospace industry, automotive industry, sports equipment design and medical equipment design, just to mention a few. Building sensitivity analysis modules that can flexibly connect with analysis and finite elements has a tremendous potential for these industries since we can provide tailored solutions for their particular needs. Not only has the optimization become more efficient but also sensitivities provide guidance on determining the importance of variables by their effect on other system components.
