Electrostatic Boundaries and Excitations

Specify at least one of the following excitations as a source of electric fields:

• The charge on a surface or object.
• The volume charge density inside an object.
• The voltage difference between conducting surfaces and objects. Define the electric potential on each surface and object using a voltage excitation.

Include at least one of the following as a reference for computing the electric potential:

• A voltage excitation.
• An odd symmetry (flux normal) boundary.
