Patent ID: 7058527

Claim:
A computer-implemented method, comprising receiving an input of a parameter of a micromagnetization vector assigned to a center of a divided microelement of an area to be analyzed, and a parameter of vector potential assigned to a side or node of the microelement; generating a magnetic field equation for providing an external magnetic field for micromagnetization using the input parameters, and initializing a time; obtaining a solution of the magnetic field equation; obtaining a time integral of Landau Lifshitz Gilbert (LLG) equation using the solution as an external magnetic field for an unstationary LLG equation; determining whether or not micromagnetization obtained by the time integral satisfies a convergence condition; correcting the magnetic field equation using the obtained micromagnetization when the convergence condition is not satisfied, and stepwise increasing the time; and repeating the process of obtaining a solution of the magnetic field equation and subsequent processes.
