A Sensitivity-Based Design Environment

Abstract

This report contains a summary and highlights of the work funded by the Air Force under AFOSR Grant F49620-98-1-0246, titled "A Sensitivity-Based Design Environment". This effort, funded under the Defense University Research Instrumentation Program (DURIP), was conducted by the Center for Optimal Design and Control (CODAC), at Virginia Tech during the period 1 February 1998-31 January 1999. The objective of the grant was to assemble the computational facilities to implement a sensitivity-based design environment. In recent years researchers at CODAC have developed mathematical foundations and a computational framework for the rapid calculation of design-sensitivities for aerospace applications. Implementation requires approximate solution of certain linear partial differential equation. In aerodynamic applications, for example, these solutions describe in linear approximation how the flow will change with a given change in a (geometric) design parameter. We have acquired an SGI Origin 2000 computer with 16 processors and two SGI Octane workstations to provide the computational platform for these calculations.
