Abstract
We introduce the SNiMoWrapper, an FMI-compatible software tool which enables the integration of models with an integrated, adapted solver in the form of a co-simulation FMU into simulation tools by conducting the co-simulation and hiding its details from the simulator. We describe the used algorithm in detail, give a short proof for the order of convergence of the SNiMoWrapper, show results for its application to an academic test example and describe an industrial proof-of-concept application.
