DESC solves for and optimizes 3D MHD equilibria using pseudo-spectral numerical methods and automatic differentiation.

The theoretical approach and implementation details used by DESC are presented in these papers [1]_ [2]_ [3]_ [4]_ and documented at Theory_.
Please cite our work if you use DESC!

Quick Start
===========

.. role:: console(code)
   :language: console

The easiest way to install DESC is from pypi: :console:`pip install desc-opt`

For more detailed instructions on installing DESC and its dependencies, see Installation_.
The code is run using the syntax :console:`desc <path/to/input_file>` and the full list of command line options are given in `Command Line Interface`_. (Note that you may have to prepend the command with :console:`python -m`)
DESC requires an input file to specify the equilibrium and solver options, and can also accept VMEC input files.
Refer to Inputs_ for documentation on how to format the input file.
The equilibrium solution is output in a HDF5 binary file, whose format is detailed in Outputs_.

As an example usage, to use DESC to solve for the equilibrium of the high-beta, D-shaped plasma described with the DSHAPE input file, the command from the :console:`DESC` directory is
:console:`desc -p examples/DESC/DSHAPE`
Where the :console:`-p` flag tells DESC to plot the results once it finishes.
