English abstract:
In our contribution, we extend a P1 finite element scheme for the
discretization of the Landau-Lifshitz-Gilbert equation (LLG), which
has originally been proposed by Alouges [1] for a simpler model
problem. Unlike prior works [2], [5], we allow arbitrary
contributions to the effective field and elaborate the circumstances
under which weak subconvergence towards a weak solution can
mathematically be guaranteed. Our analysis particularly includes
nonlinear, non-local, and/or time-dependent operators. In addition,
we investigate coupling of LLG to the full Maxwell´s equations and to
the conservation of momentum equation in order to include
magnetostrictive effects.
