✨ OpenFOAM Package Index (OPI)

styro automatically discovers packages from the community-maintained OpenFOAM Package Index.

styro install cfmesh

🖥️ Local packages

Install packages from your local filesystem:

styro install /path/to/my-custom-package

Pro tip: Add a metadata.json file to the package directory to customize installation behavior.

🌎 Git repositories

Install directly from any Git repository:

styro install https://github.com/username/my-openfoam-package.git

Just like local packages, add a metadata.json file to the repository root for custom installation settings.
