JOHANNES KEPLER UNIVERSITY LINZ Institute of Computational Mathematics A frequency-robust solver for the time-harmonic eddy current problem

چکیده
This work is devoted to fast and parameter-robust iterative solvers for frequency domain finite element equations, approximating the eddy current problem with harmonic excitation. We construct a preconditioned MinRes solver for the frequency domain equations, that is robust (= parameter– independent) in both the discretization parameter h and the frequency ω.

JOHANNES KEPLER UNIVERSITY LINZ Institute of Computational Mathematics A Robust Preconditioned-MinRes-Solver for Distributed Time-Periodic Eddy Current Optimal Control
This work is devoted to distributed optimal control problems for time-periodic eddy current problems. We apply the multiharmonic approach to the optimality system and construct a new preconditioned MinRes solver for the system of frequency domain equations. We show that this solver is robust with respect to the space discretization and time discretization parameters as well as all involved “bad...
متن کاملJOHANNES KEPLER UNIVERSITY LINZ Institute of Computational Mathematics A Robust FEM-BEM MinRes Solver for Distributed Multiharmonic Eddy Current Optimal Control Problems in Unbounded Domains
This work is devoted to distributed optimal control problems for multiharmonic eddy current problems in unbounded domains. We apply a multiharmonic approach to the optimality system and discretize in space by means of a symmetrically coupled finite and boundary element method, taking care of the different physical behavior in conducting and non-conducting subdomains, respectively. We construct ...
متن کاملChromosomal Aneuploidies and Early Embryonic Developmental Arrest
Background Selecting the best embryo for transfer, with the highest chance of achieving a vital pregnancy, is a major goal in current in vitro fertilization (IVF) technology. The high rate of embryonic developmental arrest during IVF treatment is one of the limitations in achieving this goal. Chromosomal abnormalities are possibly linked with chromosomal arrest and selection against abnormal fe...
