Abstract
Co-simulation methods can be used advantageously not only in the field of multidisciplinary simulations, but also to parallelize large monodisciplinary dynamical models. This paper focuses on the reduction of computation time that can be achieved in the simulation of multibody systems by partitioning a monolithic model into a variable number of coupled subsystems. The connection between the subsystems can be described in various ways. In this work, different subsystems are coupled by nonlinear constitutive equations (applied-force coupling approach). Exchange of coupling information takes only place at distinct macro-time points. The essential point is that the subsystems are integrated independently of each other between the macro-time points. If a Jacobi-type co-simulation scheme is used, all subsystems can be solved in parallel.
