AC conduction analysis is used to analyze electric field caused by time-harmonic voltages applied. The dielectric media is assumed to be non-ideal with a small but non-zero 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.
QuickField can perform AC conduction analysis for 2-D and axisymmetric models. The program is based on Poisson's equation. Following options are available for this analysis:
Material properties: air, orthotropic materials with constant electric permittivity and electric conductivity.
Loading sources: voltages, and concentrated electric currents.
Boundary conditions: prescribed potential values (voltages), prescribed values for normal derivatives (surface electric currents), and prescribed constraints for constant potential boundaries.
Postprocessing 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.
Special features: electric forces can be used for stress analysis (electro-structural coupling); power losses can be used as heat sources (Joule heating) for thermal analysis (electro-thermal coupling).
