This paper presents a comprehensive approach for CAD based geometry handling in support of single and multidisciplinary
analysis and design. Unlike previous schemes, the model presented here allows for hands-on automated
meshing, a requirement for design studies. Multidisciplinary analysis is handled through solid modeling constructs,
using the geometry as a transfer media. For design applications, the engineer specifies the design space directly by the
parameters of the CAD model. Key defining values in the model specified during part synthesis are later exposed to
carry out design studies and optimization. Proper layout and definition of the CAD model facilitates design changes
and use across all stages of design. A turbine blade model suitable for detailed aero/structural/thermal analysis is
used to illustrate these concepts.
