Abstract
A method for determining an optimum design includes determining an initial field solution for a design configuration based on an initial set of design variables; determining an adjoint solution to the field solution; determining the regions of interest on the design configuration based on magnitudes and/or gradients of the adjoint solution; and establishing design variables at the regions of interest.
