Simulation-oriented Transformation of CAD models

Andrae René, Peter Köhler, University of Duisburg-Essen

Abstract. Computations and simulations during the design process are performed with a variety of Computer-Aided Design (CAD) systems. For the integration of analytical calculation methods, KBE (Knowledge-Based Engineering) approaches have been integrated quite successfully. This is particularly true for parameter-oriented inference mechanisms. Numerical methods require further developed methods especially in the consolidation between design and simulation models. This paper presents a methodological approach that automates the model transformation from the design to simulation environment. This approach bases upon so-called “smart” component models, which are processed rule-based and are enriched with component-specific knowledge for the integration of design, computation and simulation. By using simulation-oriented features and components, the preprocessing becomes more efficient. Comprehensive products, rising product variants and the flexible reaction to customer requirements increases the complexity of the developing process. To tackle these demands more integrated methods and software tools are required. CAD has become a standard tool for the development process in many companies. Due to extensive possibilities of modern CAD-software, the classic approach turns into a more integrated one. This opens up the possibility to regard influences from the production and computation at an early stage of the design process, which leads to a higher complexity in the simulation process as well.

Keywords. CAD, Model transformation, FE-analysis, Knowledge-Based Engineering
