Periodic Adjoint Sensitivity Analysis
Julian Sarpe, Andreas Klaedtke, Herbert De Gersem
This paper proposes the utilization of a periodic Parareal with a periodic coarse problem to efficiently perform adjoint sensitivity analysis for the steady state of time-periodic…
Transient Forward Harmonic Adjoint Sensitivity Analysis
Julian Sarpe, Andreas Klaedtke, Herbert De Gersem
This paper presents a transient forward harmonic adjoint sensitivity analysis (TFHA), which is a combination of a transient forward circuit analysis with a harmonic balance based a…
A Stabilized Circuit-Consistent Foil Conductor Model
Elias Paakkunainen, Jonas Bundschuh, Idoia Cortes Garcia +2
The magnetoquasistatic simulation of large power converters, in particular transformers, requires efficient models for their foils windings by means of homogenization techniques. I…
Transmission operators for the non-overlapping Schwarz method for solving Helmholtz problems in rectangular cavities
Nicolas Marsic, Christophe Geuzaine, Herbert De Gersem
In this paper we discuss different transmission operators for the non-overlapping Schwarz method which are suited for solving the time-harmonic Helmholtz equation in cavities (i.e.…
Tensor train based isogeometric analysis for PDE approximation on parameter dependent geometries
Ion Gabriel Ion, Dimitrios Loukrezis, Herbert De Gersem
This work develops a numerical solver based on the combination of isogeometric analysis (IGA) and the tensor train (TT) decomposition for the approximation of partial differential…
Approximation and Uncertainty Quantification of Systems with Arbitrary Parameter Distributions using Weighted Leja Interpolation
Dimitrios Loukrezis, Herbert De Gersem
Approximation and uncertainty quantification methods based on Lagrange interpolation are typically abandoned in cases where the probability distributions of one or more {system} pa…
A Structural Analysis of Field/Circuit Coupled Problems Based on a Generalised Circuit Element
Idoia Cortes Garcia, Herbert De Gersem, Sebastian Schöps
In some applications there arises the need of a spatially distributed description of a physical quantity inside a device coupled to a circuit. Then, the in-space discretised system…
Isogeometric Analysis and Harmonic Stator-Rotor Coupling for Simulating Electric Machines
Zeger Bontinck, Jacopo Corno, Sebastian Schöps +1
This work proposes Isogeometric Analysis as an alternative to classical finite elements for simulating electric machines. Through the spline-based Isogeometric discretization it is…
A Defect Corrected Finite Element Approach for the Accurate Evaluation of Magnetic Fields on Unstructured Grids
Ulrich Römer, Sebastian Schöps, Herbert De Gersem
In electromagnetic simulations of magnets and machines one is often interested in a highly accurate and local evaluation of the magnetic field uniformity. Based on local post-proce…
