title: Data simulada de Procesos Físicos Ferro Magnetismo

description: This study validates the potential of SimuDS, a native system dynamics (SD) software implemented in R, for simulating ferromagnetic properties through phenomenological and spatial models. The objective was to demonstrate that SD can reproduce fundamental features of phase transitions and hysteresis while providing a reproducible computational framework. The methodology integrated Landau 0D equations for equilibrium analysis and hysteresis, complemented by two-dimensional Ginzburg–Landau simulations to capture spatial domain dynamics.
