Micro Abstract:
An approach for controlling the macro-step size in connection with explicit co-simulation methods is suggested. The method is tailored for applied-force coupling techniques. Each macro-time step is carried out with two different explicit co-simulation methods. By comparing the variables of both results, an error estimator for the local error can be constructed. A step-size controller for the macro step-size can be implemented. Examples are presented demonstrating the applicability and accuracy.
