An Efficient Algorithm using a Meshfree Method for Nonlinear Electromagnetic Field Computation

This paper outlines a numerical procedure based on the magnetic field computation taking the hysteresis into account. The scalar Preisach model is integrated into a meshfree element-free Galerkin (EFG) method analysis. The hysteretic nonlinearity is handled by the fixed point iterative technique. The developed algorithm was applied to study an electromagnetic device containing a ferromagnetic core. Numerical simulations highlight, among other, the power of the EFG method in terms of time computation and accuracy. Results were compared to those provided by finite element (FE) method.
