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…
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…
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…
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…
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…
Efficient Reduced Magnetic Vector Potential Formulation for the Magnetic Field Simulation of Accelerator Magnets
Laura A. M. D'Angelo, Dominik Moll, Andrea Vitrano +5
The major advantage of reduced magnetic vector potential formulations (RMVPs) is that complicated coil structures do not need to be resolved by a computational mesh. Instead, they…
Quasi-3D Magneto-Thermal Quench Simulation Scheme for Superconducting Accelerator Magnets
Laura A. M. D'Angelo, Yvonne Späck-Leigsnering, Herbert De Gersem
To tackle the strong multi-scale problem in the quench simulation of superconducting accelerator magnets, this work proposes a hybrid numerical method which uses two-dimensional fi…
Quasi-3-D Spectral Wavelet Method for a Thermal Quench Simulation
Jonas Bundschuh, Laura A. M. D'Angelo, Herbert De Gersem
The finite element method is widely used in simulations of various fields. However, when considering domains whose extent differs strongly in different spatial directions a finite…
Magnetodynamic Finite-Element Simulation of Accelerator Magnets
H. De Gersem, I. Cortes Garcia, L. A. M. D'Angelo +1
This lecture note describes how to set up and what is behind a magnetodynamic field simulation for an accelerator magnet. The relevant formulation of Maxwell's equations is derived…
