Design sensitivities are derived via the direct and adjoint methods for fully coupled nonlinear systems. These sensitivity derivations may then be used to create a concurrent engineering design environment where the individual systems are the product analyses and manufacturing process analyses. The sensitivity information, in turn, may be used in a trade-off study to quantify how product or manufacturing design changes affect any performance functional, e.g. cost, mass, stress, or cooling rate. Finally, it is noted that the necessary operator required for the sensitivity analyses is, in fact, the tangent operator of the coupled system analysis; and that this operator may be partitioned to take advantage of existing software capabilities.
