The `Tokamak Modeling and Meshing Software (TOMMS) <https://doi.org/10.1016/j.cpc.2023.108982>`_ is used for the generation of meshes for XGC simulations. 
The tool is accessible to authorized users at:

`TOMMS Github Repository <https://github.com/SCOREC/tomms>`_

A user guide to use the tool can be found at:

`TOMMS User Guide <https://github.com/SCOREC/Fusion_Public/wiki/Tokamak-Modeling-and-Meshing-Software-(TOMMS)-User's-Guide>`_

The detailed description of individual parameters to control the geometry and meshing is avaialale at:
