If you have a question about this talk, please contact Alex Bespalov. The nonlinear Landau-Lifshitz-Gilbert equation (LLG) describes time-dependent micromagnetic phenomena in terms of a magnetization field m which solves LLG . Numerical challenges arise from an inherent non-convex constraint |m| = 1 and a possibly nonlinear coupling with other partial differential equations to describe, e.g., magnetostrictive effects or the interaction of m with spin-polarized currents. In our talk, we will discuss numerical integrators which are proved to be unconditionally convergent in the sense that any CFL -type coupling of the space discretization and the time stepping is avoided. A particular focus will be on IMEX -type integrators which also decouple the time stepping of LLG and the coupled second PDE .
