The Capriccio method developed during Sebastian’s doctorate couples a particle-based domain with a continuum. It concurrently employs molecular dynamics and the Finite Element Method. At present, the Capriccio method is being enhanced for more complex systems and it is also part of the individual research grant “Identification of Interphase Properties in Nanocomposites” by the German Research Foundation (DFG) as well as of the Research Training Group GRK 2423 “FRASCAL – Fracture across Scales”.
