A generic FMU interface for modelica

• This paper discusses technical issues and implementation of a generic interface to import a Functional Mock-up Unit (FMU) into Modelica simulators, specifically the Open- Modelica environment. Whereas other approaches for importing the FMUs rely on functionality specific to the simulator environment, this approach tries to provide a generic Modelica interface for embedding an FMU to be imported into a Modelica model. In this way any FMU conforming to the Functional Mock-up Interface (FMI) for Model Exchange v1.0 Specification for model exchange from MODELISAR can be imported into any Modelica simulator. When importing an FMU into a model, the resulting Modelica model can be used just like any pure Modelica models. Hence, a better reusability and interoperability for both sides, namely the external models provided via FMI and the Modelica environment, are achieved.
