Is it possible to model hysteresis with Flux?
Altair EmployeeThe hysteresis is a complex phenomenon related to physically irreversible processes. In fact, at a given moment the value of a material property depends not only on the intrinsic properties of the material, but also on its ‘history’. Since, there is an infinite number of possible B(H) curves, modeling of the whole hysteresis is a difficult problem.
In Flux version 12.1, the Jiles and Atherton model has been implemented and allows modelling static hysteresis effects. The model used in Flux is an isotropic, vector and static Jiles-Atherton (J-A) model. This model is composed by 5 parameters that the user must still. A Matlab tool is available with Flux and allows identifying these parameters from major hysteresis loop measures.
This model is available in 2D and 3D only for transient magnetic applications.
