DC conduction

DC conduction

The DC conduction (current flow) module allows to simulate DC current distribution in conducting media. In QuickField DC Conduction module the currents may be induced by voltages applied to conductors, or the known current density on the region boundaries. The DC Conduction analysis module complements other types of electrical field analysis, available in QuickField - Electrostatic and AC Conduction.
The DC conduction module can be used to design and analyze variety of conductive systems such as ground connectors, PCB, biological objects in biomedical researches, and others.

Starting from version 6.2 DC Conduction analysis is possible not only in 2D Plane-Parallel and 2D axisymmetrical formulations, but also as a 3D Extrusion and 3D Import.

Features of the DC Conduction module:

  • Anisotropic conductivity
  • Voltage and current density sources
  • Dirichlet or Neumann boundary conditions
  • Results: Voltage, current density, electric field, power losses, electric current through a surface, and other integral quantities
  • Couplings: power losses can be used as heat sources (Joule heating) for thermal analysis (electro-thermal coupling)
