Because of geometry based communication between CAD and CAE system, their integration is still an open problem. Currently tedious manual process for CAE modeling and lacking of high level explanation to CAE analysis result significantly restrict the use of CAE. With the development of concurrent design and computer integrated manufacturing, there strongly exists a need for the integration of CAD and CAE. In this paper, a feature based product information model was built, and a feature based CAE modeling method and feature knowledge based intelligent explanation mechanism for CAE analysis result were discussed. With feature as a carrier of information, the integration between commercial CAD and CAE system was achieved and a case study of stamping part was presented to demonstrate the feasibility.
