Assigning a Volume Charge Density Excitation for an Electrostatic Solver

This type of excitation defines the volume charge density on an object.

To define the charge density on a 3D object:

1. Select the 3D section of the geometry on which you want to apply the excitation.
2. Click Maxwell > Excitations > Assign > Volume Charge Density.
   The Volume Charge Density 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 charge density in the Value box.
5. In the Parameters section, select the type of coordinate system from the Coordinate System drop-down menu.
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.
