Assigning a Current Excitation for a Magnetostatic Solver

Specifies the total current in a conduction path. The conduction path may be contained completely within the problem region (for example, a coil), or may touch the edges of the problem region.

To set a current excitation:

  1. Select the section of the geometry (i.e., the conductor) on which you want to apply the excitation (typically a face or other 2D planar object).
  2. Click Maxwell > Excitations > Assign > Current.
    The Current Excitation window appears.
  3. Enter a name for the excitation in the Name box, or accept the default.
  4. In the Parameters section, specify the following options:
    1. Enter a value for the current in the Value box, and select the units from the drop-down menu.
    2. Select Solid or Stranded as the Type of conductor. For a stranded conductor, a uniformly distributed current density is assumed.
    3. Click Swap Direction to change the direction of the current flow.
  5. Optionally, click Use Defaults to revert to the default values in the window.
  6. Click OK to assign the excitation to the selected object.
