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
