Simulation and digital twin for mechatronic product design

The use of digital twins and simulation models to construct, evaluate and validate designs has become an intrinsic part of every product creation process. The use in production, operation and service has been increasing in the last years, for example model predictive control or simulation-based assist systems. The challenges - and opportunities - however are multifold. Interoperability of models, model transformation and co-simulation are key to realize system level simulation. Computing performance alone cannot address the requirements posed by ever more complex systems and applications like massive design space exploration or interactive simulation, expressing the need for disruptive solver solutions. But also modeling technology needs to be extended. Integrating the digital twin with data measured on the physical assets, reusing all previously established engineering knowledge, allows new applications such as virtual sensing, model based control and hybrid system modeling including hardware, software and numerical components.
