Installation

CubitPy is developed with python3.12. Other versions of Python might lead to issues. It is recommended to use a python environment container such as conda or venv.

• conda: A conda environment can be created and loaded with

  conda create -n cubitpy python=3.12
  conda activate cubitpy

• venv: Chose an appropriate directory for this, e.g., /home/user/opt. A virtual environment can be setup with
  • On Debian systems the following packages have to be installed:

    sudo apt-get install python3-venv python3-dev

  • Create and load the environment

    cd <path-to-env-folder>
    python -m venv cubitpy-env
    source cubitpy-env/bin/activate

To install cubitpy go to the repository root directory

cd path_to_cubitpy

And install cubitpy via pip

pip install .

If you intend to actively develop cubitpy, install it in editable mode

pip install -e .

To run CubitPy it is required to set an environment variable with the path to the Cubit directory. This should be the "root" directory for the installation.

export CUBIT_ROOT=path_to_cubit_root_directory

To check if everything worked as expected, run the tests from within the tests directory

cd path_to_cubitpy/tests
pytest -q testing.py

If you intend to actively develop CubitPy, please make sure to install the pre-commit hook within the python environment to follow our style guides:
