Error Analysis and Error Estimates for Co-simulation in FMI for Model Exchange and Co-Simulation v2.0

Conference paper
Part of the Differential-Algebraic Equations Forum book series (DAEF)

Abstract

Complex multi-disciplinary models in system dynamics are typically composed of subsystems. This modular structure of the model reflects the modular structure of complex engineering systems. In industrial applications, the individual subsystems are often modelled separately in different mono-disciplinary simulation tools. The Functional Mock-Up Interface (FMI) provides an interface standard for coupling physical models from different domains and addresses problems like export and import of model components in industrial simulation tools (FMI for Model Exchange) and the standardization of co-simulation interfaces in nonlinear system dynamics (FMI for Co-Simulation), see https://www.fmi-standard.org/. The renewed interest in algorithmic and numerical aspects of co-simulation inspired some new investigations on error estimation and stabilization techniques in FMI for Model Exchange and Co-Simulation v2.0 compatible co-simulation environments. In the present paper, we focus on reliable error estimation for communication step size control in this framework.

Blochwitz (Dresden), H. Elmqvist, H. Olsson (Lund), M. Otter (Oberpfaffenhofen) and other partners of the MODELISAR consortium. The work was supported by the German Minister of Education and Research, BMBF projects 01IS08002N and 03MS633A. The research on the convergence analysis for modular time integration methods applied to coupled systems in block representation was inspired by fruitful discussions with M. Busch (Kassel).
