Sensitivity Calculations for Poisson's Equation via the Adjoint Field Method

The Adjoint Variable Method for the Sensitivity Analysis of Multibody

Extended Abstract The multibody system approach is widely used for analyzing the dynamic behavior of mechanical systems with large motions, and several programs are available for this task 1]. But there is still a lack of tools for synthesizing nonlinear dynamic systems systematically. This synthesis requires an optimal choice of the system parameters with respect to a given performance measure...

Revised methods for Adjoint Calculations

A common class of shielding problems involves the calculation of biological dose rates from large distributed sources at localised positions. A typical example is that of calculating the dose at points around a transport cask. Sophisticated variance reduction methods must be used in Monte Carlo calculations to sample from the important parts of the source and to propagate particles towards the ...

Adjoint sensitivity computations for an embedded-boundary Cartesian mesh method

1 Introduction Cartesian-mesh methods [I] are perhaps the most promising approach for addressing the issues of flow solution automation for aerodynamic design problems. In these methods, the discretization of the wetted surface is decoupled from that of the volume mesh. This not only enables fast &id robust mesh generation for geometry of arbitrary cQing&eziQ:> but &o facili@$es _accezs to geoa...

Wing Planform Optimization via an Adjoint Method

This dissertation focuses on the problem of wing planform optimization for transonic aircraft based on flow simulation using Computational Fluid Dynamics(CFD) combined with an adjoint-gradient based numerical optimization procedure. The adjoint method, traditionally used for wing section design has been extended to cover planform variations and to compute the sensitivities of the structural wei...
