Abstract:

The results of the Phase I study on Design Optimization of Systems Governed by Partial Differential Equations are presented. The optimization algorithm used is the Pironneau-Polak method of feasible directions with Armijo step size. This algorithm, and related ones are uniquely applicable to practical engineering and science problems whose constraints are defined implicitly in terms of possibly discontinuous functionals of the solution to te PDEs. The objective cost and constraint functions are evaluated by execution, from the optimization code, of a separate and complex user-oriented PDE code gradients are determined numerically. Feasibility is convincingly demonstrated by the design optimization of several practical laser electrode problems.
