modeFRONTIER 4.3 is a multidisciplinary and multi-objective optimization and design environment, written to allow easy coupling to almost any computer aided engineering (CAE) tool, whether commercial or in-house. Many companies today take advantage of virtual prototyping rather than physical testing for the former is usually faster and less expensive. With these purposes in mind ESTECO 2011 has developed a combination between virtual prototyping and experimental data calculation: the platform modeFRONTIER 2011, aimed at streamlining the entire design process. Optimization is the key to reach this goal, achievable through integration with multiple calculation tools and explicable by effective post-processing tools. Applications modeFRONTIER is being used in a wide range of applications across all industry sectors. Since almost every industry that involves advanced engineerign uses CAE packages, modeFRONTIER is expected to be a well-suited tool to push the envelope in product design.
