This paper discusses technical issues and implementation of a generic interface to import a Functional Mock-up Unit (FMU) into Modelica simulators, specifically the OpenModelica 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 i...

Since the FMI technology gains ground in industrial environment, the demand for robust co-simulation increases. In a master-slave concept the master algorithms define the quality of a co-simulation whereas the properties of the coupled FMUs for co-simulation restrict the variety of possible master algorithms. In this paper an existing experimental master tool with three basic master algorithms ...

The mild chronic inflammatory state associated with obesity may be an important link between adiposity and insulin resistance (IR). In a sample of 137 overweight and obese Chilean adolescents, we assessed associations between high-sensitivity C-reactive protein (hs-CRP), IR and adiposity; explored sex differences; and evaluated whether hs-CRP mediated the relationship between adiposity and IR. ...

We discuss the application of the FMI Co-Simulation technology to building energy performance simulation, where detailed physical building models are coupled to Modelica-based HVAC component and plant models. First, we describe the generation process of the building FMU from our stand-alone building simulation program NANDRAD and sketch out internal algorithms for FMI version 2 capabilities. Th...

Digital twins enable the observation, prediction, and optimization of a physical system thus allow to realize their full potential. However, functionality is mainly based on simulation models entire behavior. For modular multi-domain systems, this requires extensive use dynamically composed that are made up individual component models. The FMI-Standard forms solid foundation for problem very we...
