Abstract

The improved performance and capacity of networks has made the combined processing power of workstation clusters a potentially promising avenue for solving computationally intensive problems across such distributed environments. Moreover, networks provide an ideal platform to employ heterogeneous hardware and software to solve multibody dynamics problems. One fundamental difficulty with distributed simulation is the requirement to couple and synchronize the distributed simulations. This paper focuses on the algorithms necessary to couple together separately developed multibody dynamics modules so that they can perform integrated system simulation. To identify a useful coupling strategy, candidate numerical algorithms in the literature are reviewed briefly - namely, stiff time integration, local parameterization, waveform relaxation, stabilized constraint and perturbation. An unobtrusivealgorithm that may well serve this `gluing' role is presented. Results from numerical experiments are presented and the performance of the gluing algorithm is investigated.
