AC conduction analysis
AC Conduction
The AC Conduction module can be used to analyze electric field caused by timeharmonic voltages and currents on the region boundaries. The dielectric media is assumed to be nonideal with a small but nonzero electric conductivity. Generally the quantities of interest in AC Conduction analysis are voltages, active and reactive currents, electric fields, Joule losses, capacitances, and electric forces. The AC Conduction analysis module complements other types of electrical field analysis, available in QuickField  Electrostatic and DC Conduction, taking into account both resistive and capacitive effects.
The AC Conduction module can be used to design and analyze variety of conductive systems such as capacitors, insulation systems cables, and in other technical applications.
Features of the AC Conduction module:
 Anisotropic conductivity
 Anisotropic permittivity
 Voltage and current density sources
 Dirichlet or Neumann boundary conditions
 Results: voltages, electric fields, conductive and reactive (displacement) current densities, flux densities (electric displacements), Joule losses, self and mutual capacitances, forces, torques, and electric energy
 Couplings: power losses can be used as heat sources (Joule heating) for thermal analysis (electrothermal coupling). Electric forces can be used for stress analysis (electrostructural coupling)
See examples of AC Conduction problems:
Plane capacitor
Cylindrical capacitor
Slot insulation.
