Direct Preisach Hysteresis Model for Finite Element Analysis.
This project deals with the numerical analysis of ferromagnetic hysteresis in the laminated media by direct characteristic. The direct scalar or vector Preisach model is integrated into the two and three dimensional finite element analysis. The interface between the Preisach model and the finite element formulation is the fixed point iterative technique.
The main goals of this project are the implementation of the direct model in the nonlinear static magnetic fields and in the nonlinear eddy current fields, and the numerical analysis of three dimensional laminated problems e.g. transformers, electrical machines.
The first step in this project is solve the Problem No. 32 of the TEAM Workshops, and the numerical results are validated by comparison with the experiments.
