Assigning a Current Excitation for the Eddy Current Solver

Specifies the total AC 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 specify the total AC current:

1. Select the 2D section of the geometry on which you want to apply the excitation.
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. Enter the current strength in the Value box.
5. Enter the phase for the current in the Phase box.
6. 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.
Note: The Solid/Stranded setting is not available for a 3D Eddy Current A-F design. The Solid type is always used for this type of design.
7. Optionally, click Ref. Direction to change the direction of the current flow.
8. Optionally, click Use Defaults to revert to the default values in the window.
9. Click OK to assign the excitation to the selected object.
