ParaStell

Parametric 3D CAD modeling tool for stellarator fusion devices. This toolset takes VMEC plasma equilibrium data to build intra-magnet components of varying thickness from a user-specified radial build, as well as corresponding coil filament point-locus data to build magnet coils of user-specified cross-section.

Dependencies

This tool depends on:

• The VMEC tools developed by @aaroncbader
• CadQuery
• MOAB
• Coreform Cubit or Cubit by Sandia National Laboratories
• cad-to-dagmc
• Gmsh

Install with Mamba

This guide will use the mamba package manager to install dependencies in a conda environment. Conda allows for easily installing and switching between different versions of software packages through the use of environments.

If you have not already installed conda, you can use one of the following installers to do so: Miniconda, Anaconda, or Miniforge.

Mamba is available through conda with conda install -c conda-forge mamba. Begin by creating a new conda environment with mamba installed.

conda create -n parastell_env
conda activate parastell_env
conda install -c conda-forge mamba

The subsequent mamba and pip install commands should be run with this environment activated.

Install Dependencies using Mamba and Pip

Install ParaStell dependencies available on conda-forge.

mamba install -c conda-forge cadquery moab

Install pystell_uw dependencies.

mamba install matplotlib

Pip install remaining pystell_uw dependency.

pip install netCDF4

Pip install remaining ParaStell dependencies.

pip install cad-to-dagmc
pip install gmsh

Coreform Cubit

Download and install version 2023.11 from Coreform's Website, then add the /Coreform-Cubit-2023.11/bin/ directory to the PYTHONPATH by adding a line to the .bashrc file like the following:

export PYTHONPATH=$PYTHONPATH:$HOME/Coreform-Cubit-2023.11/bin/

Replace $HOME with the path to the Cubit directory on your system. Additional information about adding modules to the PYTHONPATH can be found here. While it is possible to use ParaStell with older versions of Cubit, additional steps not in this guide may be required.

If you do not have a Cubit license, you may be able to get one through Cubit Learn at no cost.
