The sequence shows one cycle in the design process. The upper left figure illustrates the packaging of engine, axle, transmission, and HVAC components. The image to the right is the design space for the components. The organic red shape, from OptiStruct, is a density plot indicating an optimal structure. The recognizable grid of beams is an engineering and manufacturable interpretation of the OptiStruct plot. The rectangular beams have been optimized for size and the final picture shows components and structure.
