Co-simulation

In co-simulation the different subsystems which form a coupled problem are modeled and simulated in a distributed manner. Hence, the modeling is done on the subsystem level without having the coupled problem in mind. Furthermore, the coupled simulation is carried out by running the subsystems in a black-box manner. During the simulation the subsystems will exchange data. Co-simulation can be considered as the joint simulation of the already well-established tools and semantics; when they are simulated with their suitable solvers. Co-simulation proves its advantage in validation of multi-domain and cyber physical system by offering aflexible solution which allows consideration of multiple domains with different time steps, at the same time. As the calculation load is shared among simulators, co-simulation also enables the possibility of large scale system assessment.

Establishing a co-simulation framework can be a challenging and complex task because it requires a strong interoperability among the participating elements, especially in case of multiple-formalism co-simulation. Harmonization, adaptation and eventually changes of actual employed standards and protocols in individual models need to be done to be able to integrate into the holistic framework. The generic layered structuration of co-simulation framework highlights the intersection of domains and the issues that need to be solved in the process of designing a co-simulation framework. In general, a co-simulation framework constitutes of five abstraction layers:
