Abstract

This paper introduces severalmethods of cooperative simulation. Apart from the general classification and method descriptions, the numerical stability and consistency of one loose coupling approach is discussed. It is shown that consistency is maintained, although possibly of lower order, and zero stability persists as long as no algebraic dependencies between partial systems occur. The methodology of Jacobi-Type loose coupling is applied for a case study using the cosimulation tool BCVTB. The study shows that this tool is well suited for the fast co-simulation of many instances of certain simulators, but allows no synchronisation step size control and only equidistant synchronization step sizes.
