desc.vmec.VMECIO.load

classmethod VMECIO.load(path, L=None, M=None, N=None, spectral_indexing='ansi', profile='iota')[source]

Load a VMEC netCDF file as an Equilibrium.

Parameters:

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

  • L (int, optional) – Radial resolution. Default determined by index.

  • M (int, optional) – Poloidal resolution. Default = MPOL-1 from VMEC solution.

  • N (int, optional) – Toroidal resolution. Default = NTOR from VMEC solution.

  • spectral_indexing (str, optional) – Type of Zernike indexing scheme to use. (Default = 'ansi')

  • profile ({"iota", "current"}) – Which profile to use as the equilibrium constraint. (Default = 'iota')

Returns:

eq (Equilibrium) – Equilibrium that resembles the VMEC data.

Notes

To ensure compatibiltiy with different profile representations in VMEC, the resulting equilibrium will always have SplineProfile types for all profiles
