Abstract: 
Magnetic patterns of ferromagnetic materials are described by the well-accepted model of Landau and Lifshitz. Over the last years, different strategies have been developed to tackle the related non-convex problem: direct minimization, convexification, and relaxation by using Young measures. Nonstationary ferromagnetic effects are considered by the extended model of Landau, Lifshitz and Gilbert (LLG). In the talk, we survey numerical analysis for solving the stationary problem. In the second part, we discuss proper projection/penalization strategies to discretize (LLG).
