Assigning a Charge Excitation for a 2D Electrostatic Solver

This type of excitation defines the total charge on a surface or object. The potential distribution on the object with charge excitation is computed during the solution.

To define a charge excitation:

1. Select the section of the geometry on which you want to apply the excitation.
2. Click Maxwell 2D > Excitations > Assign > Charge.
   The Charge Excitation dialog box appears.
3. Enter a name for the excitation in the Name box, or accept the default.
4. In the Parameters section, enter the numerical value, parameter (design or project variable) or a spatial function in the Value box.
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.
