Abstract

The effect of approximations in the discrete adjoint on constrained shape optimization is investigated. The different approximations are compared with the exact discrete adjoint, which is capable of producing exact gradient/sensitivity information. The purpose of such a comparison is to understand whether or not approximate adjoint codes can be effective for shape optimization in spite of the error in the computed gradient.
