On bridging domain methods to couple particle‐ and finite‐element‐based simulations

Abstract

This contribution investigates schemes to couple domains of different resolutions in space, a problem frequently arising in multi-scale modelling of materials. To couple a standard finite element domain with a high resolution atomistic or molecular, i.e. particle-based domain, a so-called bridging domain is considered, e.g. Xu and Belytschko [1], Zhang, Khare, Lu and Belytschko [2] and Bauman et al. [3]. The main goal is to separate the computation of finite element and atomistic domains as much as possible, amongst others, to calculate the different domains on several CPUs.
