What magnetic calculation engine does it use?
SimulMag uses single-domain models to calculate the magnetic behavior of individual elements. Static and dynamic calculations are implemented. The static calculation is based on a semi-analytical Stoner-Wohlfarth model, while the dynamic method solves the Landau-Lifshitz torque equations. The elements interact via magnetostatic interactions and user specified exchange interactions. Fields due to applied currents are taken into account in the calculations. A complete description of the mathematical implementation of the physical model that represents the electromagnetic calculation aspects of the software can be found in Chapter 4 of the user’s manual.
