Machwave is a Python library for chemical propulsion simulation. The library makes it easy to model solid or biliquid rocket engines, analyse performance and integrate the results into trajectory simulations.
Getting Started
Installation
Install Machwave using pip:
pip install machwave
macOS prerequisite: gfortran
Machwave depends on rocketcea, which does
not publish macOS wheels on PyPI. On macOS, pip therefore builds rocketcea from
source and needs a Fortran compiler. Homebrew's gcc formula installs only
versioned binaries (e.g. gfortran-15), so an unversioned gfortran symlink
must be added to PATH before pip install machwave:
brew install gcc
ln -sf "$(ls "$(brew --prefix)"/bin/gfortran-* | sort -V | tail -n 1)" "$(brew --prefix)/bin/gfortran"
Linux and Windows users do not need this step — rocketcea ships prebuilt wheels for those platforms.

Development Setup
If you're contributing to Machwave, you'll need uv for dependency management.
Installing uv
macOS / Linux:
curl -LsSf https://astral.sh/uv/install.sh | sh
Windows (PowerShell):
powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
For more details, visit the official uv installation guide.
Clone and Install
Clone the repository and install dependencies:
git clone https://github.com/felipebogaertsm/machwave.git
cd machwave
make install
Publishing a New Release
-
Create a release on GitHub with a tag matching
vX.Y.Z(e.g.v1.2.0). The version is derived automatically from the git tag. -
The publish workflow builds the package and publishes it to PyPI via trusted publishing (OIDC).
