To display the lifetime of each specimen digitally the group Digital Twin and Simulation is focused on the simulation of all experiments conducted on the spin test and MTC test facilities. It aims to create a digital twin of each test stand and specimen with all its characteristics. Using the digital twins it is possible to validate the simulations in real time by linking simulation and experiment. This way it is also possible to gain additional understanding of the material behavior. The results will be integrated in the Virtual Engine.
