Assigning a Current Density Excitation for a 2D Transient Solver

This command specifies the applicable component (depending on the XY or RZ type of application) of the transient current density in an object. If the current density is a function of position, the value is entered in ampere/m², even if you change the units in the problem.

To define the current density:

1. Select the section of the geometry (i.e., the conductor) in which you want to apply the excitation (typically a 2D object).
2. Click Maxwell 2D > Excitations > Assign > Current Density.
   The Current Density Excitation dialog box 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 the current strength in the Value box. The value may be a single numeric value or a spatial function.
2. If a spatial function is entered for the Value, select the Coordinate System from the drop-down menu.
5. Optionally, click Use Defaults to revert to the default values in the dialog box.
6. Click OK to assign the excitation to the selected object.
