Excerpt

You can generate an FMU (Functional Mock-up Unit) for external co-simulation of dynamic models that enables the exchange of simulation results between different simulation tools. The generated FMU exposes the defined input and output parameters of a model, as specified in a Simulation Configuration. The generated FMU runs the server-side simulation of a particular Simulation Configuration using given inputs and returns the outputs after each time step. FMUs can be generated for two platforms: Linux 64-bit and Windows 64-bit.

Note
titlePrerequisites
  • You must have OpenJDK to generate FMU from the modeling tool.
  • You must have a simulation server certificate to co-simulate the generated FMU.
  • You must use the generated FMU with tools that use the same JAVA version as the modeling tool; otherwise, you will not be able to run the generated FMU.

FMU generation uses selected Simulation Configuration properties, and can contain the following defined data:

  • Start Time, End Time and Step Size property values.
  • Input Parameters property value: the default values from the defined input parameters will be included in the generated FMU.
  • Output Parameters property value: the default values from the defined output parameters will be included in the generated FMU.


To generate an FMU

  1. Open a Teamwork Cloud project.
  2. Right-click a Simulation Configuration and select Simulation > Generate FMU.

  3. In the Generate FMU dialog specify the following:
    • In

...

    • the File Directory

...

    •  box, specify the location where the generated file should be stored.
    • Select the Win64 or Lin64 radio button, depending on the platform on which you will run the generated FMU. 

    • Optionally, select the Include login credentials check box and specify a server-side simulation server address and login credentials to be stored in the generated FMU file.

      Note

      You can leave

...

    • the Include login credentials

...

    •  check box

...

    • empty and provide the login credentials later as FMU parameters while importing an FMU file. In this case, the credentials will not be stored in the generated FMU file.
