OMPython is a Python interface that uses ZeroMQ to communicate with OpenModelica.

http://modelica.co.kr/board/describing-behavior/basic-equations/basic-equations_examples/an-electrical-example/

• Python 3.x supported
• PyZMQ is required

Installation using pip is recommended.

pip install OMPython

Clone the repository and 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.

The workshop/ directory contains comprehensive tutorial examples demonstrating OMPython usage:

Demonstrates heat transfer simulation using Newton's Law of Cooling.

Scripts:

• test_basic.py - Basic test and verification
• simple_example.py - Simple visualization
• simulate_cooling.py - Parameter study
• interactive_explorer.py - Interactive dashboard

Quick Start:

cd workshop/cooling
pip install -r requirements.txt
python3 test_basic.py

See workshop/cooling/README.md for details.

SMR (Small Modular Reactor) power plant simulation with thermal-to-electric conversion.

Scripts:

• test_basic.py - Basic SMR simulation test
• visualize_smr.py - Comprehensive visualizations (4-panel analysis, energy flow, transient response)
• parameter_study.py - Parameter sweeps and sensitivity analysis
• interactive_dashboard.py - Real-time interactive control

Quick Start:

cd workshop/smr
pip install -r requirements.txt
python3 test_basic.py
python3 visualize_smr.py  # Generates 3 visualization plots

See workshop/smr/README.md for details.

Model Equations:

dT_core/dt = (Q_fission - Q_transfer) / (m_coolant * Cp)
Q_transfer = UA * (T_core - T_steam)
P_electric = Q_transfer * eff_thermal

• Submit bugs through the OpenModelica GitHub issues.
• Pull requests are welcome.

It is recommended to set up pre-commit to automatically run linters:

# cd to the root of the repository
pre-commit install
