CAD/CAE Associative Features for Cyclic Fluid Control Effect Modeling

Lei Li, Yongsheng Ma, University of Alberta

Abstract. Interfacing CAD and CAE tools is widely recognized as a technical gap without a general solution. There are two commonly applied approaches to establish the integration: one is to develop an integrated system with both CAD and CAE modules equipped, for which the feature-based techniques are supposed to maintain the semantic information during model conversion; the other is to develop a unified feature model incorporated with both CAD and CAE information, with which both CAD and CAE views could be extracted and the information consistency could be easily sustained. In this extended abstract, CAD/CAE associative feature is proposed to manage the geometric and semantic associations between CAD and CAE models based on the well-established associative feature concept. In addition, CAE boundary feature is put forward as a robust tool to maintain information consistency during the conversion. CAE effect feature is introduced by extracting the sensitivity information from the CAE results which are necessary for guiding the design modification properly. By utilizing these new concepts, a new CAD/CAE integration framework has been developed, which covers both the forward and reverse integrations and supports the automated cyclic product development.

Keywords. CAD/CAE Associative Feature, CAE Boundary Feature, CAE Effect Feature, Design Automation, CAD/CAE Integration
