Exploiting features for finite element model generation

The preparation of simulation models from CAD models is still a difficult task since shape changes are often required to adapt a component or a mechanical system to the hypotheses and specifications of the simulation task. Detail removal or idealization operations are among the current treatments performed during the preparation of simulation models. In this paper we introduce the concept of simplification features, which allows a user to improve the efficiency of the analysis model generation process. As a result, form feature semantics and simulation data are attached to a polyhedral model during the preparation phase to ease the Finite Element(FE) details identification and removal as well as to maintain the consistency between a CAD model and its associated F.E models.
