Coupling field analysis and non-deterministic optimization by means of multiprocessor parallel computation for characterizing magnetic anisotropy

The paper proposes an automated procedure for linking an identification algorithm implemented in a general-purpose environment (MatLab™) with a commercial Finite-Element code for magnetic field analysis (VF-Opera™). This procedure is applied to identify automatically the B-H curve of anisotropic magnetic laminations in the direction normal to the sheet surface. A multiprocessor computer made it possible to perform parallel computations. An identification procedure based on a non-deterministic algorithm allows finding the whole B-H curve for sheet samples.
