Coupling of intrusive and non-intrusive locally decomposed model order reduction techniques for rapid simulations of road systems (B05)

• Subject Area: Mechanics ; Applied Mechanics, Statics and Dynamics
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 453596084

TP B05 is concerned with the development of a novel coupled intrusive-nonintrusive model order reduction (MOR) technique, which allows to link purely data-based input-output correlations with physics-based models. By means of the local decomposition, the special structure of multi-physical problems can be taken into account. The new method is used to create a substitute model of the detailed tire-road system (TP A01), such that real-time calculations become feasible within the digital twin of the road system. TP B05 is essential to enable fast simulations of road systems under consideration of uncertain data (TP B04).
