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…

Transient Nonlinear Electrothermal Adjoint Sensitivity Analysis for HVDC Cable Joints
M. Greta Ruppert, Yvonne Späck-Leigsnering, Herbert De Gersem
Efficient computation of sensitivities is a promising approach for efficiently of designing and optimizing high voltage direct current cable joints. This paper presents the adjoint…

Multivariate sensitivity-adaptive polynomial chaos expansion for high-dimensional surrogate modeling and uncertainty quantification
Dimitrios Loukrezis, Eric Diehl, Herbert De Gersem
This work develops a novel basis-adaptive method for constructing anisotropic polynomial chaos expansions of multidimensional (vector-valued, multi-output) model responses. The ada…
