The study 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). The method is used to identify the B-H curves of anisotropic magnetic laminations in the direction normal to the sheet surface with the aid of a multiprocessor computer to benefit from parallel computing. The proposed approach, based on a non-deterministic algorithm, makes it possible to determine the entire B-H curve and is therefore an advancement on the commonly used assumption of constant permeability.
