Coupling simulations: A simple way to increase results accuracy

Coupling simulations from different domains is becoming increasingly important, considering the evolution of CAE toward multi-physics problems. As an example, utilizing residual stress/strain as well as thinning information from metal-forming simulation is gaining rapid acceptance in the structural CAE community. Most of the time, components of full-car crash models are defined independently from any residual stresses and strains, and thicknesses are considered as nominal, whereas a lot of these ones have been manufactured thru stamping or bending processes.
