Note

The pip installation uses the h5py backend by default, which does not require MOAB/pymoab. As pymoab is not currently available on PyPi it can’t be included in the PyPi distributed pip cad_to_dagmc pip package. If you want to use pymoab backend and you installed via pip you’ll need to install MOAB separately. The Conda/Mamba installed version of cad-to-dagmc includes pymoab.

Optional: Installing pymoab#

pymoab is optional and only needed if you want to use the h5m_backend="pymoab" option.

Option 1: Via Conda

conda install -c conda-forge moab

Option 2: Via extra index

pip install --extra-index-url https://shimwell.github.io/wheels moab

Option 3: From source

pip install git+https://bitbucket.org/fathomteam/moab/

Optional: Installing OpenMC#

To use the generated h5m files in neutronics simulations, you’ll need a DAGMC-enabled transport code like OpenMC.
