SQP method for adjoint based aerodynamic shape optimization

cfdbooks · May 25, 2009, 05:33

Could anyone tell me how to use the SQP(NPSOL package)method for adjoint based aerodynamic shape optimization? Or give me some references in detail. Thanks in advance.

Learn LNKS (Lagrange-Newton-Krylov-Schur) first, it provides a more powerful framework and RSQP drops out as an unpreconditioned and generally suboptimal case. Read the Biros & Ghattas papers, or the Akcelik et al. survey.

Thank you Jed. But I can not understand. Will NPSOL give a searching direction? I can not input objective function and constrains(also their gradients) analytically but in discrete form.
