Assigning a Balloon Boundary Condition for a 2D Electrostatic Solver

To set a balloon boundary:

1. Select the section of the geometry on which you want to apply the boundary condition (typically an edge).
2. Click Maxwell 2D > Boundaries > Assign > Balloon.
   The Balloon Boundary dialog box appears.
3. Enter a name for the boundary in the Name box, or accept the default.
4. Select Voltage or Charge as the Balloon Type.
5. Optionally, click Use Defaults to revert to the default values in the dialog box.
6. Click OK to assign the boundary to the selected object.
