Omnigenous Umbilic Stellarators

This repository contains all the data and analysis files used to generate and analyze omnigenous umbilic stellarators in this preprint. These script were written to run with commit 24887e4af18f9a2b7da6b5161ccb11d277a4704c To reproduce these results, you must install/build DESC (not the pip install way) and

git checkout 24887e4af18f9a2b7da6b5161ccb11d277a4704c

The only files that have been removed are four large data files (> 100 MB) such as output from the FIELDLINES code and mgrid files which can be generated by running FIELDLINES and DESC.

The structure of files and directories is shown below
