Stellarators are a promising type of fusion reactor that can run in steady-state with a low risk of disrupting. They need to be optimized for good particle confinement, however, and their complicated geometry makes these calculations expensive. We have developed the code DESC to compute three-dimensional equilibria by solving the magnetohydrodynamic force balance equations. In contrast to other stellarator equilibrium codes, DESC is fast, accurate, flexible, and easy to use. Our hope is that DESC will become a powerful tool for the design and operation of modern stellarator experiments.
