Product: Abaqus/Standard
Benefits: You can now perform a transient eddy current analysis that accounts for full coupling between the electric and magnetic fields.
Description: You can now calculate the eddy currents that are induced in a conductor placed within a time-varying magnetic field. The magnetic field can be generated by a coil carrying a time-varying current, or it can be specified directly by means of appropriate boundary conditions/loads. The solution procedure is based on obtaining a transient solution to Maxwell's equations describing electromagnetic phenomena under the low-frequency assumption and, hence, accounts for strong coupling between the electric and the magnetic fields. Transient eddy current analysis is available with two-dimensional (planar) and three-dimensional continuum elements and is based on an element edge-based interpolation of fields instead of the usual node-based interpolation. The transient eddy current analysis can be driven by prescribed volume and/or surface current density vectors or by prescribed values of the magnetic vector potential on surfaces. The magnetic behavior of the medium can be linear or nonlinear and must be defined everywhere in the domain. Nonlinear magnetic behavior can be defined in terms of one or more B–H curves. Electrical conductivity must be defined in the conductor regions.
