One of the main difficulties in micromagnetics simulation is the severe time step constraint introduced by the exchange field. Using standard explicit integrators leads to a physical time step of sub-pico seconds, which is often two orders of magnitude smaller than the fastest physical time scales.
In 1991 A. D. Gunawardena et al. reported that the convergence rate of the Gauss-Seidel method with a preconditioning matrix Z + S is superior to that of the basic iterative method. In this paper, we use the preconditioning matrix Z + S(a). If a coefficient matrix A is an irreducibly diagonally domi
In the case of convection dominated problems, multigrid methods require an appropriate smoothing to ensure robustness. As a first approach we discuss a GauΓ-Seidel smoothing with a correct numbering of the unknowns and if necessary a special block partitioning. Numerical experiments show that, in th
