Advanced Time-Domain Finite-Element Method for Electromagnetic Analysis
Time-domain finite-element method (TDFEM) is studied for electromagnetic analysis. Solutions to a series of open problems that impede the popularity of the TDFEM are presented. These problems include the development of accurate and efficient absorbing boundary conditions for the mesh truncation of …

Nonlinear electromagnetic-thermal modeling using time domain finite element method in the machinery design
… (EM) and heat transfer processes, the time-domain finite element method is employed for its capability of modeling complex geometries. Losses generated from EM fields lead to temperature increase, while the temperature change, in turn, modifies material properties and thus affects EM …
