Assigning a Current Excitation for a 3D AC Conduction Solver

Note: This Current excitation is also applicable to the Eddy Current A-F solver.

To define a current across a surface:

  1. Select the 2D section of the geometry on which you want to apply the excitation.
  2. Click Maxwell 3D > 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:

    1. Enter the current strength in the Value box, and select the unit from the drop-down menu.
    2. Enter the phase angle in the Phase box, and select the unit from the drop-down menu.
    3. Select either Solid or Stranded to define the Type for the conductor. For a stranded conductor, a uniformly distributed current density is assumed without considering eddy effects.
      4. Note: The Solid/Stranded setting is not available for a 3D Eddy Current A-F design.
    4. Optionally, to change the direction of the current flow, click Ref. Direction.
  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.
