Introduction
• FEA is „de-facto“ standard in all industries for virtual product development
• After 60 years of FEA efficient application has still much room for improvement
• Software development is still primarily feature and function driven

Introduction
• Strategic aspects are still not of majotinterest– Methodology development– Integration of simulations into development
and innovation processes
• Main cause for lack of efficiency is conflict between– Software training– Application of software for specific tasks

Benefits of Simulation Process Modelling
• Disadvantage– Simulation process model must have a
minimum detail and completeness level• Needs critical mass of potential applications
• Benefits are significant and manifold– typically short-term noticeable

innovations– More freedom in design decisions– Design changes can be evaluated without
building physical prototypes• Advantages are not only limited to
component level– Impact also on system level
