This paper presents a framework of performing aerodynamic shape optimization using the feature-based CAD system, which is widely used in aerospace industry. An interface is set up to communicate between the system installs the CAD package and the system installs the CFD solver. Mesh is adapted to fit the new CAD model after each parametric update by performing surface mesh deformation and volume mesh deformation in sequence. The proposed framework can be easily integrated into the industrial product design and analysis process.
