7 Automotive Grid Challenges in Automotive Industry The challenge of integrating different disciplines: –Design (CAD) –Simulation (CAE) –Test (CAT) different locations different organisations

8 Automotive Only the CAE engineer knows, which part is used and in which form it is represented Product Structure - Simulation Structure CAD – CAE Integration Situation: For build-up of a simulation model structural information geometric and material data from CAD are needed Structure differs from load case to load case Geometric representation of the parts differs from load case to load case
