Adaptive multigrid and domain decomposition methods in the computation of electromagnetic fields
The authors propose the use of efficient and robust adaptive multigrid and domain decomposition methods for the computation of electromagnetic field in the low-frequency regime, which describe the quasistationary limit of Maxwell's equations based on curl-conforming edge element discretizations. Emphasis is on hybrid smoothing and nonmatching grids (mortar edge elements) as well as on adaptive grid refinement relying on residual type a posteriori error estimate. Numerical results are presented in order to illustrate the performance of the multigrid solver for the computation of eddy currents in converter modules as electric drives for high-power electromotors.
