Python-Based eSES/MB Infrastructure

H. Folkerts


Abstract

The Python-based extended System Entity Structure / Model Base (eSES/MB) infrastructure has been developed by the research group Computational Engineering and Automation (CEA) at Wismar University of Applied Sciences. It is intended to automatically execute a number of simulation experiments using the components in the figure below. It extends the ideas of the SES/MB framework introduced by B.P. Zeigler with new modeling features, methods, and components. These extensions allow the automatic processing of SES as well as automatic model generation and execution.


Extended SES/MB Infrastructure for Modeling and Simulation.


Motivation

Today's simulation softwares provide powerful numerical methods for simulation, but lack comprehensive support for the conceptual modeling phase. In order to tackle this lack, the research group CEA developed the SES Toolbox for MATLAB/Simulink. The toolbox implements the components and methods of the eSES/MB framework and supports model generation for MATLAB/Simulink models, but lacks general interfaces for an Execution Unit and an Experiment Control as well as support for different simulation software. The Python toolset offered on this site provides general interfaces with special focus on the possibilty to support different simulation environments.

Software

The Python-based eSES/MB infrastructure consists of following tools available as OpenSource software on GitHub: The tools have a comprehensive documentation in the file "doc.pdf" in the main directory of each tool (except for SESViewEl). In the documentation of SESToPy an introduction and background information to the eSES/MB infrastructure is given.
Currently SESMoPy supports the simulators Simulink, OpenModelica and Dymola natively. A general interface supported by a number of simulators is the Functional Mock-up Interface (FMI). SESMoPy supports model generation via FMI. Advantage of using FMI is that a general non simulator specific modelbase can be used to support all simulators. Please see the documentation of SESMoPy for more information.

Usage

Detailed information are provided in the documentation of the respective tool (except for SESViewEl).
Quick start information for the software are provided in the readme files of the respective tool.
For using this infrastructure the following steps need to be taken:
