Reusage and reanalysis of simulation data in structural dynamics

PN 7-6

Project description

The aim of this project is the reusage of previous simulation data to approximate, accelerate and improve future simulations. To this end, the corresponding dynamic bio and structural mechanics problems are analysed under the aspect of data-based approximations. For each of the resulting problem classes the success of such an approach of data reuse is investigated.
