Stellarator Geometry
====================

At the moment the stellarator version is separate from the main XGC code and located in `XGC-Devel/XGC-S <https://github.com/PrincetonUniversity/XGC-Devel/tree/master/XGC-S>`_. It is CPU only and limited to the closed flux-surface region (core) using VMEC as input for the magnetic equilibrium.
