  6. 4. Design Automation for Multidisciplinary Optimization : A High Level CAD Template Approach

    Author : Mehdi Tarkian; Johan Ölvander; Xiaolong Feng; Fredrik Elgh; Linköpings universitet; []
    Keywords : ;

    Abstract : In the design of complex engineering products it is essential to handle cross-couplings and synergies between subsystems. An emerging technique, which has the potential to considerably improve the design process, is multidisciplinary design optimization (MDO).MDO requires a concurrent and parametric design framework.
