On the proper treatment of grid sensitivities in continuous adjoint methods for shape optimization
Surface and field integral-based continuous adjoint sensitivities revisited. The effect of grid/mesh sensitivities on accuracy, in continuous adjoint. Physical interpretation of the so-called Leibniz term. Continuous adjoint including the adjoint to hypothetical grid displacement PDE. New, enhanced adjoint formulation, both cheap and accurate.
