Using Parametric Effectiveness for Efficient CAD-Based Adjoint Optimization

Parametric effectiveness is a measure of the ability of the parameters defining a CAD model to be used for optimization. It compares the optimum change in performance that can be achieved using a CAD model’s parameterization, to the maximum performance improvement that could be obtained if the model is free to move. In this work, the approach is applied to the shape optimization of an S-Bend duct for minimizing the power-loss and an automotive car mirror for minimizing the noise perceived by the driver of the car.
