A question about the material model of hysteresis

yugang

Hello 

I try to use hysteretic, preisach model described by 4 parameters of a typical cycle.

I try to get some information or formula of the model , but i can not find it in help document.

Can any one share the excate B-H formular definition using these 4 parameters.

It is tanh used right ? But i want to the mathmatic formular used for B-H curve calculation.

Thanks.

Hello

most of the information is on this page : https://help.altair.com/flux/Flux/Help/english/UserGuide/English/topics/HystereticMaterialsInFlux_IsotropicPreisach.htm?hl=preisach

 

I recommend you to use the Material Identification tool in order to fit any curve you have to these parameters if needed

Yes, I have already read this page, and also i use material identification tool.

But, can you share the excat formular used to create B-H curve.

 

Below it is formular used in activate.

Does Flux use same formular.

Thanks.
