modelGenericHystTellinenHard
Generic flux tube with hard magnetic hysteresis based on the Tellinen model and simple tanh()-functions
Extends from BaseClasses.GenericHysteresisTellinen (Partial Tellinen hysteresis model).
Information
Flux tube element for modeling the ferromagnetic (static) hysteresis of hard magnetic materials. The ferromagnetic hysteresis behavior is defined by the Tellinen hysteresis model. The shape of the limiting hysteresis loop is described by simple hyperbolic tangent functions with 4 parameters.
