Linear second-order IMEX-type integrator for the (eddy current) Landau–Lifshitz–Gilbert equation
No full textCombining ideas from Alouges et al. (2014, A convergent and precise finite element scheme for Landau–Lifschitz–Gilbert equation. Numer. Math., 128, 407–430) and Praetorius et al. (2018, Convergence of an implicit-explicit midpoint scheme for computational micromagnetics. Comput. Math. Appl., 75, 1719–1738) we propose a numerical algorithm for the integration of the nonlinear and time-dependent Landau–Lifshitz–Gilbert (LLG) equation, which is unconditionally convergent, formally (almost) second-order in time, and requires the solution of only one linear system per time step. Only the exchange contribution is integrated implicitly in time, while the lower-order contributions like the computationally expensive stray field are treated explicitly in time. Then we extend the scheme to the coupled system of the LLG equation with the eddy current approximation of Maxwell equations. Unlike existing schemes for this system, the new integrator is unconditionally convergent, (almost) second-order in time, and requires the solution of only two linear systems per time step

Simple error estimators for the Galerkin BEM for some hypersingular integral equation in 2D
No full textA posteriori error estimation is an important tool for reliable and
efficient Galerkin boundary element computations. For hypersingular
integral equations in 2D with positive-order Sobolev space, we
analyze the mathematical relation between the (h− h/2)-error
estimator from [Ferraz-Leite, Praetorius 2008], the two-level error
estimator from [Maischak, Mund, Stephan 1997], and the averaging
error estimator from [Carstensen, Praetorius 2007]. All of these a
posteriori error estimators are simple in the following sense: First,
the numerical analysis can be done within the same mathematical
framework, namely localization techniques for the energy norm.
Second, there is almost no implementational overhead for the
realization
