desc.objectives.get_fixed_axis_constraints

class desc.objectives.get_fixed_axis_constraints(eq=None, profiles=True, iota=True, kinetic=False, anisotropy=False, normalize=True)Source

Get the constraints necessary for a fixed-axis equilibrium problem.

Parameters:

• profiles (bool) – Whether to also return constraints to fix input profiles.

• iota (bool) – Whether to add FixIota or FixCurrent as a constraint.

• kinetic (bool) – Whether to add constraints to fix kinetic profiles or pressure

• anisotropy (bool) – Whether to add constraint to fix anisotropic pressure.

• normalize (bool) – Whether to apply constraints in normalized units.

Returns:

constraints, tuple of _Objectives – A list of the linear constraints used in fixed-axis problems.
