Assigning a Current Excitation for a DC Conduction 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 > 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, enter the current strength in the Value box.
5. Optionally, to change the direction of the current flow, click Swap Direction.
6. Optionally, click Use Defaults to revert to the default values in the window.
7. Click OK to assign the excitation to the selected object.
