An Iterative Method for Transient Finite Element Simulations of Non-Linear Eddy Current Problems
Karl Hollaus, Haik Silm
A method is presented to carry out a transient simulation of eddy current problems with nonlinear materials. Coils are voltage-driven. The magnetic field due to currents in coils a…
Multiscale Finite Element Formulations for 2D/1D Problems
Karl Hollaus, Markus Schöbinger
Multiscale finite element methods for 2D/1D problems have been studied in this work to demonstrate their excellent ability to solve real-world problems. These methods are much more…
An Equilibrated Error Estimator for the 2D/1D MSFEM T-Formulation of the Eddy Current Problem
Markus Schöbinger, Karl Hollaus
The 2D/1D multiscale finite element method (MSFEM) is an efficient way to simulate rotating machines in which each iron sheet is exposed to the same field. It allows the reduction…
Effective Medium Transformation: the Case of Stratified Magnetic Structures
Markus Schöbinger, Karl Hollaus, Igor Tsukerman
Effective medium theory replaces a given fine-scale heterostructure with a homogeneous one in such a way that the physically measurable quantities, e.g. reaction fields and losses,…
