Eddy current analysis

Eddy current problems:

  • involve coupling between electric and magnetic fields, which are solved for simultaneously;

  • solve Maxwell's equations describing electromagnetic phenomena under the low-frequency assumption that neglects the effects of displacement currents;

  • require the use of electromagnetic elements in the whole domain;

  • require that magnetic permeability is specified in the whole domain and electrical conductivity is specified in the conducting regions;

  • allow for both time-harmonic and transient electromagnetic solutions;

  • allow predefined conductor translation and rotation;

  • calculate as output variables, rate of Joule heating and intensity of magnetic body forces associated with eddy currents, and these output variables can be transferred from a time-harmonic electromagnetic solution to drive a subsequent heat transfer, coupled temperature-displacement, or stress/displacement analysis, thereby allowing for the coupling of electromagnetic fields with thermal and/or mechanical fields in a sequentially coupled manner; and

  • can be solved using continuum elements in two- and three-dimensional space.
