Abstract

There is a strong international trend towards collaborative engineering and reduction of organizational barriers in product development (PD). The organizational changes combined with the new and evolving CAD/CAE technology strongly enable finite element analysis (FEA) to efficiently assist the engineering process. Collaborative engineering benefit from a rich and flexible modeling environment that allows conceptual finite element (FE) models of product behavior to be created, detailed and expanded throughout the products life-cycle. Requirements on a product modeling methodology with associative models of physical behavior, i.e. a meta-model approach, is presented. The methodology that is based on commercial state-of-the-art CAD/CAE software is exemplified with two case studies.
