cofmpy 0.2.0

👋 About CoFMPy

CoFMPy is a Python library designed for rapid prototyping of digital twins through the co-simulation of Functional Mock-up Units (FMUs). It offers advanced master coordination features, such as solving algebraic loops between FMUs and managing the interaction between various simulation components. This library provides a seamless interface to orchestrate complex physics simulations and handle the data exchange between FMUs.

The documentation is available online: https://irt-saint-exupery.github.io/CoFMPy

🐾 Installation

CoFMPy is available on PyPI and can be installed using pip:

pip install cofmpy

🐍 Python interface

The Python interface allows users to use CoFMPy and run co-simulation. A high-level API is provided to easily run and visualize a co-simulation system. Advanced users can also dive deeper into the structure of CoFMPy for a more advanced control of the components.

Under the hood, CoFMPy is controlled by a component called the Coordinator. It is the entry point of CoFMPy and it manages all the other components:

• the Master algorithm which is the engine that runs the co-simulation of FMUs.
• the Graph Engine that builds the connections and interactions between the FMUs and the data sources and sinks.
• the data stream handlers that control the input data required by the co-simulation system.
• the data storages that allow to store or send the outputs of the simulation.

📜 JSON configuration file

To properly define the co-simulation system, a JSON configuration file must be created. This file is the only information required by CoFMPy to run the simulation. It must respect a specific syntax in order to define the FMUs, the interactions between them, the data sources and sinks, etc.
