To meet the design challenges of tomorrow, NASA and industry require advancements in the state-of-the-art for physics-based design and analysis frameworks. In particular, NASA needs the ability to make more use of physics-based models earlier in the design process. This will allow engineers to more accurately capture the complex coupling between engineering disciplines and to more accurately simulate the complex behavior of novel design configurations. Key technical barriers include long execution times, model and data complexity, and geometry management. In the Phase II project, Phoenix Integration will expand on the successful Phase I prototypes to develop new technologies and user interfaces that will help overcome these barriers. This project will focus on (1) the development of a flexible capability for implementing Multi-Disciplinary Analysis and Optimization (MDAO) strategies (such as multi-fidelity) in ModelCenter, (2) the creation of a flexible geometry visualization and monitoring capability for high-fidelity system models, and (3) the extension of Phoenix Integration's "Plug-In" infrastructure to better support a wide range of high-fidelity analysis and geometry management tools (CAD/CAE tools, meshing tools, mesh morphing tools). These technologies will combine with other NASA funded technologies to create a robust physics-based design and analysis framework for designing next generation air vehicles.
