Remarks on the gluing algorithm for multibody systems co-simulation

This paper briefs a part of authors’ study on co-simulation techniques and their application to multibody system dynamics. The main concern of the study is on construction and properties of algorithms that are suitable for such purpose. One of the proposed methods from literature is so-called “gluing-algorithm” by Wang et al. These authors proposed Newton iteration to couple several simulators of mechanical subsystems through constraints/reactions, and provided numerical examples to suggest efficiency of the method. Here we re-investigate the method in order to underline some problems that one might meet when using the “gluingalgorithm”.
