Automated configuration for non-iterative co-simulation

Abstract

Virtual engineering becomes more and more relevant for different industries to reduce development efforts in terms of costs and time. Especially for large dynamical systems co-simulation is a promising approach for performing system simulations, where subsystems are modeled as well as simulated via tailored simulation tools in a distributed manner. In contrast to general purpose simulation tools for co-simulations an additional higher-level numerical solver (Master Algorithm) is mandatory, which has to be configured by the user and leads to significant additional application efforts: therefore benefits of modular development are strongly limited. Within this paper the occurring coupling challenge for non-iterative co-simulation is investigated and recently proposed solutions are reviewed. On this basis, the necessary information for configuration is identified and an approach for fully automated configuration of non-iterative co-simulations is derived. The proposed concepts are examined.
