Convergent tangent plane integrators for the simulation of chiral magnetic skyrmion dynamics

Gino Hrkac, Carl-Martin Pfeiler, Dirk Praetorius +3

We consider the numerical approximation of the Landau-Lifshitz-Gilbert equation, which describes the dynamics of the magnetization in ferromagnetic materials. In addition to the cl…

Linear second-order IMEX-type integrator for the (eddy current) Landau-Lifshitz-Gilbert equation

Giovanni Di Fratta, Carl-Martin Pfeiler, Dirk Praetorius +2

Combining ideas from [Alouges et al. (Numer. Math., 128, 2014)] and [Praetorius et al. (Comput. Math. Appl., 2017)], we propose a numerical algorithm for the integration of the non…

Adaptive vertex-centered finite volume methods for general second-order linear elliptic PDEs

Christoph Erath, Dirk Praetorius

We prove optimal convergence rates for the discretization of a general second-order linear elliptic PDE with an adaptive vertex-centered finite volume scheme. While our prior work…

A linear Uzawa-type solver for nonlinear transmission problems

Thomas Führer, Dirk Praetorius

We propose an Uzawa-type iteration for the Johnson-Nédélec formulation of a Laplace-type transmission problem with possible (strongly monotone) nonlinearity in the interior domain.…

Adaptive IGAFEM with optimal convergence rates: Hierarchical B-splines

Gregor Gantner, Daniel Haberlik, Dirk Praetorius

We consider an adaptive algorithm for finite element methods for the isogeometric analysis (IGAFEM) of elliptic (possibly non-symmetric) second-order partial differential equations…
