Modeling Structural - Dynamics Systems in MODELICA/Dymola, MODELICA/Mosilab and AnyLogic

With the progress in modeling dynamic systems new extensions in model coupling are needed. The models in classical engineering are described by differential equations. Depending on the general condition of the system the description of the model and thereby the state space is altered. This change of system behavior can be implemented in different ways. In this work we focus on three state-of-the-art DAE simulation environments, Dymola, Mosilab and AnyLogic, and compare the possibilities of coupling of different state spaces. This can be done either using a parallel model setup, a serial model setup, or a combined model setup. The analogies and discrepancies are figured out on the basis of the classical constrained pendulum as defined in ARGESIM comparison C7.
