Abstract

CAD-FEA coupling has been the subject of research for a long time. Initially developed with the aim of connecting single applications, requirements due to the interfaces rose along with increasing application of computer-aided methods in product development. The introduction of the termproduct data model in combination with object-oriented technology, allowed progressive work towards the integration of product data. First results have been given in form of a standardized product data model called STEP (ISO 10303) to serve for CAE product data exchange. The authors have had the opportunity to examine the data model introduced by STEP in general and depicting the CAD-FEA connection as well as to implement a prototype STEP interface.

The article first presents some fundamentals of product data modeling and related aspects of design and analysis product data, then gives a survey of the case study being done in CAD-FEA coupling with STEP and in conclusion sketches the concept of an object-oriented CAD-FEA integration model to allow for bidirectional and process conform data exchange.
