class desc.vmec_utils.make_boozmn_output(eq, path, surfs=128, M_booz=None, N_booz=None, verbose=0)Source

Create and save a booz_xform-style .nc output file.

based strongly off of https://github.com/hiddenSymmetries/booz_xform/tree/main

Parameters:

  • eq (Equilibrium) – Equilibrium to save.

  • path (str) – File path of output data.

  • surfs (int) – Number of flux surfaces to calculate Boozer transform at (Default = 128). NOTE: because this is performed on the so-called “half-grid”, this will result in an output of size surfs-1, since for surfs number of surfaces there is only surfs-1 surfaces on the half-grid, the first one being the surface at s = 0.5 / surfs where s = rho**2 is the normalized toroidal flux coordinate

  • M_booz (int, optional) – poloidal resolution to use for Boozer transform. Default is 2 * eq.M.

  • N_booz (int, optional) – toroidal resolution to use for Boozer transform.Default is 2 * eq.N.

  • verbose (int) – Level of output (Default = 1). * 0: no output * 1: status of quantities computed * 2: as above plus timing information

Returns:

None
