pyOFM: Python wrapper for OpenFOAM meshes

pyOFM

pyOFM is a Python wrapper for OpenFOAM meshes that provides a simple mesh reading class to parse OpenFOAM polyMesh directories and store mesh data in Python for user interaction.

Features

• Automatic Build System: Modern pyproject.toml-based build system with automatic Cython extension compilation
• Flexible Installation: Works with or without OpenFOAM environment (falls back to pure Python)
• OpenFOAM Integration: Direct reading of OpenFOAM polyMesh format
• Python 3.8+ Support: Compatible with Python 3.8 through 3.12
• MPI Support: Includes MPI capabilities via mpi4py

Requirements

• Python 3.8 or higher
• NumPy >= 1.16.4
• mpi4py >= 3.0.0
• OpenFOAM environment (optional, for Cython extensions)
• Cython >= 0.29.0 (for building from source)

Installation

Quick Installation (Recommended)

For most users, simply install via pip:

pip install -e .

The build system will automatically:

• Detect if OpenFOAM environment is available
• Build Cython extensions if OpenFOAM is present
• Fall back to pure Python package if OpenFOAM is not available

Building from Source Distribution

When installing from a source distribution (e.g., from PyPI):

pip install pyofm_orion

The package will automatically handle compilation during installation.

Build System

The package uses a modern build system with:

• pyproject.toml: Modern Python packaging configuration
• Automatic Extension Building: Cython extensions are built automatically during pip install
• Environment Detection: Automatically detects OpenFOAM availability
• Fallback Support: Works as pure Python package when OpenFOAM is unavailable
• Cross-Platform: Supports Linux environments with proper OpenFOAM setup
