A Reduced Magnetic Vector Potential Approach with Higher-Order Splines
Merle Backmeyer, Laura A. M. D'Angelo, Brahim Ramdane +1
This work presents a high-order isogeometric formulation for magnetoquasistatic eddy-current problems based on a decomposition into Biot-Savart-driven source fields and finite-elem…
Experimental Validation of HomHBFEM Simulations of Fast Corrector Magnets for PETRA IV
Jan-Magnus Christmann, Laura Anna Maria D'Angelo, Herbert De Gersem +5
This paper presents experimental validation of the homogenized harmonic balance finite element method (HomHBFEM), which we have developed as a dedicated simulation technique for ma…
DC-Biased Homogenized Harmonic Balance Finite Element Method
Jan-Magnus Christmann, Laura A. M. D'Angelo, Herbert De Gersem +2
The homogenized harmonic balance finite element (FE) method enables efficient nonlinear eddy-current simulations of 3-D devices with lamination stacks by combining the harmonic bal…
Homogenized harmonic balance finite element method for nonlinear eddy current simulations of fast corrector magnets
Jan-Magnus Christmann, Laura Anna Maria D'Angelo, Herbert De Gersem +5
This paper develops a homogenized harmonic balance finite element method (HomHBFEM) to predict the dynamic behavior of magnets with fast excitation cycles, including eddy current a…
A Dynamic Energy-Based Hysteresis Model for Pulsed-Operated Fast-Ramping Magnets
Dominik Moll, Laura A. M. D'Angelo, Herbert De Gersem +3
Due to the strongly nonlinear behavior of ferromagnetic yokes, the numerical analysis of fast-ramping magnets is highly cumbersome and, therefore, in practice overly simplified by…
