ModelicaRes 0.12.2

Utilities to set up and analyze Modelica simulation experiments

Set up and analyze Modelica simulations

ModelicaRes is a free, open-source tool that can be used to

• generate simulation scripts,

• load and browse data,

• perform custom calculations,

• filter and sort groups of results,

• produce various plots and diagrams, and

• export data to various formats via pandas.

The figures are generated via matplotlib, which offers a rich set of publication-quality plotting routines. ModelicaRes has methods to create and automatically label xy plots, Bode and Nyquist plots, and Sankey diagrams. ModelicaRes can be scripted or used in an interactive Python session with math and matrix functions from NumPy.

Currently, ModelicaRes only loads Dymola/OpenModelica-formatted results (*.mat), but the loading functions are modular so that other formats can be added easily.

Please see the tutorial, which is available as an IPython notebook or online as a static page. For the full documentation and many more examples, see the main website.

Installation

First, install the dependencies. Most are installed automatically if you have the setuptools module. However, SciPy >= 0.10.0 must be installed according to the instructions at http://www.scipy.org/install.html. The GUIs require Qt, which can be installed via PyQt4, guidata, or PySide.

Then install ModelicaRes. The easiest way is to use pip:

pip install modelicares

On Linux, it may be necessary to have root privileges:

sudo pip install modelicares

Another way to install ModelicaRes is to download and extract a copy of the package. The main website, the GitHub repository, and the PyPI page have copies which include the source code as well as examples and supporting files to build the documentation and run tests. Once you have a copy, run the following command from the base folder:

python setup.py install

Or, on Linux:

sudo python setup.py install

The matplotlibrc file file has some recommended revisions to matplotlib’s defaults. To use it, copy it to the working directory or matplotlib’s configuration directory. See http://matplotlib.org/users/customizing.html for details.

Credits

The main author is Kevin Davies. Code has been included from:

• Richard Murray (control.freqplot—part of python-control),

• Joerg Raedler (method to expand a Modelica variable tree—from DyMat),

• Jason Grout (ArrowLine class), and

• Jason Heeris (efficient base-10 logarithm).

Suggestions and bug fixes have been provided by Arnout Aertgeerts, Kevin Bandy, Thomas Beutlich, Moritz Lauster, Martin Sjölund, Mike Tiller, and Michael Wetter.
