Abstract

The very accurate magnetic hysteresis representation available from Preisach-based models is not currently offered in commercial finite element (FE) packages. The major obstacle to using more accurate magnetization models is that they can cause convergence problems in the FE solution cycle. A method has been developed to integrate the fast DOK (Della Torre-Oti-Kadar) model, a Preisach based magnetization model, into the ANSYS FE program. Small-scale tests show that the FE solutions match expected values and that the use of the Preisach model does not effect the convergence of the FE solution
