Automotive CAE | VDI Conference

The current debate is about unresolved issues in the field of Computer Aided Engineering, which will be addressed at the conference. Learn how the use of Artificial Intelligence (AI) and Reduced Order Modeling (ROM) can really push vehicle development in the automotive sector.

Get your simulation results even faster

Automobile manufacturing is characterised by diminishing development cycles and rising demands. In order to shorten development schedules and this way reduce costs, car manufacturers have long been relying on CAE methods. Now simulation methods like the Reduced Order Modeling plus the use of Artificial Intelligence in CAE are promising major time savings for developers. Then VDI Conference will discuss the use of AI and ROM, specifically in crash, aero and thermal simulation.

The conference will highlight current research findings and developments and show examples of industrial applications on the use of AI and ROM in computer-based vehicle development. It provides a comprehensive overview on the whole topic backed up by evidence from  enterprises and research facilities across Europe, North America and Asia.  

Top Topics

  • Real-time interactive aerodynamic and crash simulation
  • Integration of AI in CAE solvers
  • New approaches of AI and ROM in the area of vehicle safety
