In the last 20 years computer simulation has become an indispensable tool in automotive development. Tremendous progress in software and computer technology makes it possible today to assess product and process performance before physical prototypes have been built. Applications of computer simulation cover nearly all aspects of product and process design from crashworthiness to manufacturability.

Challenges in virtual vehicle development

Despite of significant progress in simulation technology and impressive results in industrial application there remains a number of challenges which prevent a “100% digital prototyping”.

Grand Challenge as a platform for dialog

The automotive CAE Grand Challenge stimulates the exchange between users, scientists and software developers in order to solve these challenges. Annually the current challenges in automotive CAE are being identified through a survey among simulation experts of the automotive industry. In the conference one session will be dedicated to each of the 6 most critical challenges, the “Grand Challenges”. In each session CAE experts from industry, research and software development will explain the importance of the individual Challenge for the virtual development process and talk about their efforts to solve the challenge.
