* MagneticsProblem Class for solving magnetics problems.

this = MagneticsProblem( model )

Construct problem, where model is an instance of RFmodel or MotorModelBase class.

Main methods:

solve_static : solve static problem with no damping effects.
solve_harmonic : solve harmonic problem.
solve_stepping : solve time-stepping problem.

* MagneticsProblem/get_component_property is a function.

prob = get_component_property(this, component, property, pars)

* MagneticsProblem/set_boundary_matrix is a function.

this = set_boundary_matrix(this, varargin)

* setting PM sources, if any

* solve_harmonic Harmonic solution of a MagneticsProblem.

Solves a Harmonic magnetics problem, with sinusoidal time-variations.

solution = solve_harmonic(this, pars), where

pars : a SimulationParameters object
solution : a HarmonicSolution object.

Note: setting pars.isDC = true is recommended for synchronous machines; in this case the rotor is rotated by 90 electrical degrees for the imaginary/sinusoid component of the solution, compared to the real/cosinusoid part. This provides an approximation of the effect of rotor saliency.

NOTE: The real and imaginary fields are coupled in the rotor, which is incorrect for synchronous machines (as f_rotor = 0). As a result, the rotor reluctivity gets overestimated. This may be fixed in a future release. In the meantime, see MagneticsProblen.solve_quasistatic.

* solve_quasistatic Quasi-static a MagneticsProblem.

Almost like solve_harmonic with the ‘isDC’ parameter set to true; but only damping-related coupling between the d- and q-axes.

NOTE: Will probably be merged into solve_harmonic in the future.

* solve_static Static solution of a MagneticsProblem.

Solves a static magnetics problem, with no damping effects.

solution = solve_static(this, pars), where

pars : a SimulationParameters object
solution : a StaticSolution object.

* solve_stepping Time-stepping solution of a MagneticsProblem.

Solves a time-stepping problem.
