DESC

New Features Add profiles for kinetic quantities to Equilibrium Add compute functions and objectives for the bootstrap current for stellarators near quasisymmetry. Added ability to solve equilibria with the axis held fixed, or by constraining the O(rho) behavior from a near axis expansion. New objective for penalizing plasma-vessel distance All objectives now have a bounds argument, and the loss will be zero if within bounds. Added compute functions for field line quantities such as field line label alpha, unit vector b, field line curvature kappa etc. Add compute functions for covariant components of current. Equilibrium.compute will now automatically use the correct grids for surface and volume averages. Added a number of fields to VMEC output from DESC equilibria. Minor Changes Improved handling of indefinite hessian matrices in fmintr Bug Fixes Fix issue with composite profiles parsing parameters incorrectly Loading an equilibrium from VMEC now uses spline profiles to ensure consistency, as VMEC does not always save the input profile Full Changelog: https://github.com/PlasmaControl/DESC/compare/v0.7.2...v0.8.0If you use this software, please cite it using the metadata from this file.
