OMPython is a Python interface that uses ZeroMQ or CORBA (omniORB) to communicate with OpenModelica.

• Python 2.7 and 3.x supported
• PyZMQ is required

• Currently, only Python 2.7 is supported
• omniORB is required:
  • Windows: included in the OpenModelica installation
  • Linux: Install omniORB including Python 2 support (the omniidl command needs to be on the PATH). On Ubuntu, this is done by running sudo apt-get install omniorb python-omniorb omniidl omniidl-python

Installation using pip is recommended.

Install the latest OMPython master by running:

python -m pip install -U https://github.com/OpenModelica/OMPython/archive/master.zip

Install the version packed with your OpenModelica installation by running:

cd %OPENMODELICAHOME%\share\omc\scripts\PythonInterface
python -m pip install -U .

To Install the latest version of the OMPython master branch only, previously cloned into <OMPythonPath>, run:

cd <OMPythonPath>
python -m pip install -U .

Running the following commands should get you started

import OMPython
help(OMPython)

from OMPython import OMCSessionZMQ
omc = OMCSessionZMQ()
omc.sendExpression("getVersion()")

or read the OMPython documentation online.
