A novel co-simulation algorithm, referred to as the Interface-Jacobian-based Co-Simulation Algorithm (IJCSA), has been developed. The algorithm can solve co-simulation scenarios involving an arbitrary number of fields and signals. Due to the fact that the IJCSA is based on the residual form it handles algebraic loops in a natural manner. Furthermore, the individual simulators can run in parallel without flow dependency reducing the wall-clock time of the simulation, since the subsystems do not have to be executed using the classical Gauss-Seidel pattern. A thorough stability analysis of the IJCSA is presented. Furthermore, the practical applicability of the algorithm is demonstrated by solving a fully coupled emergency brake maneuver of a wind turbine.
