The software SESMoPy has been developed by the research group Computational Engineering and Automation (CEA) at Wismar University of Applied Sciences. The software implements a modelbuilder according to the System Entity Structure / Model Base (SES/MB) infrastructure introduced for automatic execution of simulation experiments. The focus of the software is the model generation for different simulators. Please read the documentation for further information. A comprehensive introduction to the SES/MB theory is given in the documentation of the SES modeling tool SESToPy. The software is written in Python3 with PyQt5 as user interface. It was tested with the simulation softwares Matlab R2018a (for Simulink), OpenModelica 1.12.0, and Dymola 2018. Furthermore it makes use of the FMU Compliance Checker developed by Modelon AB.


Copy the directory SESMoPy in your home folder, e.g. C:\Users\<Username> (necessary if simulation models are built for Dymola, simulation cannot be executed in Dymola otherwise). Make sure, that the command "omc" is on the path and the program is thus startable from the shell (needed for model generation using the Functional Mock-up Interface (FMI)). If models using FMI model generation are built for Dymola, the command "dymola" has to be on the path as well. This is described in the documentation in detail.
The program can be executed from source. Python3 with PyQt5 needs to be installed and the Python executable needs to be on the path. Open a shell and change with the cd command to the SESMoPy directory. The program then can be started with the shell command:

  • in Windows: python
  • in Linux: python3

Build as executable
SESMoPy can alternatively be built as executable for Windows and Linux. More information on this is in the documentation. This is not preferred and not tested in new program versions. The created executable file in the program directory has the name "SESMoPy".



  • Usage of the Experimental Frame

  • Simulink models can be nicely arranged with the Matlab command: Simulink.BlockDiagram.arrangeSystem('<systemname>');
