Release v0.5.2 · PlasmaControl/DESC

Major Changes

New objectives for MercierStability and MagneticWell
Change LinearGrid API to be more consistent with other Grid classes:
- L, M, N now correspond to the grid spectral resolution, rather than the number of grid points
- rho, theta, zeta can be passed as integers to specify the number of grid points (functionality that used to belong to L, M, N)
- rho, theta, zeta still retain their functionality of specifying coordinate values if they are not integers
- Other code that depends on LinearGrid was updated accordingly to use the new syntax
Poloidal grid points are now shifted when sym=True to give correct averages over a flux surface.
Added default continuation steps to converted VMEC input files

add option to plot_comparison and plot_surfaces to not plot vartheta contours
Add better warnings for gpu and jax issues
add volume avg force and pressure gradient to the compute functions
change is_nested function to use jacobian sign instead of looking for intersections between surfaces
Allow alternate computation of multi-objective derivatives, computing individual jacobians and blocking together rather than computing all at once.

Fix nfev=1 and Some scalar solver Issues
Fix some formula errors in second derivatives of certain magnetic field components, caused by some hanging expressions.
fix bug where node pattern is always jacobi when force is used as objective
Allow hdf5 to store None attributes correctly
Fix profile parity and Z axis coefficients in VMECIO.save
Ensure axis coefficients are updated correctly after solving equilibrium
