SFILES 2.0 is an open-source Python package for converting process flow diagrams (PFDs) and piping and instrumentation diagrams (P&IDs) into an extended text-based representation. This package is developed in conjunction with the paper:

SFILES 2.0: An extended text-based flowsheet representation

The repository provides tools for:

• Representing flowsheets as graphs
• Converting graphs to SFILES 2.0 strings and back
• Demonstrating the notation rules, structure, and conversion algorithm for SFILES 2.0

If you use SFILES 2.0 in your work, please cite:

Install the package via pip:

pip install SFILES2

To explore the source code and examples:

git clone https://github.com/process-intelligence-research/SFILES2.git cd SFILES2 pip install .

Use the following to explore SFILES 2.0 capabilities:

• Run the Jupyter notebook demonstration.ipynb
• Or execute run_demonstration.py for a CLI-based example

These demonstrate SFILES 2.0 strings for a variety of PFDs and P&IDs.
