Design Sensitivity Analysis of Large-Scale Constrained Dynamic ...

WebDesign sensitivity analysis in ABAQUS is performed using the semianalytical method. The issue of obtaining accurate sensitivities with respect to design shape parameters using this method has been discussed extensively in the literature (for example, Pedersen et al., 1989; Barthelemy and Haftka, 1990; Fenyes and Lust, 1991; and Van Keulen and De Boer, 1998). WebA design sensitivity analysis can be restarted (see “Restarting an analysis,” Section 9.1.1). However, DSA must have been active in the base analysis, and no design parameter or gradient data can be modified in the restart run. The restarted analysis will follow all the DSA propagation rules that are applicable to a regular analysis. 08就33-1 https://meg-auto.com
