Getting Started: A 2D Electrostatic Problem
5. Click Assign>Boundary>Balloon. The balloon1 boundary appears in the Boundary list, and
the following types of balloon boundaries appear at the bottom of the window:
Charge Models an electrically insulated system. That is, the charge at infinity
balances the charge in the problem region, forcing the net charge to be zero.
Voltage Models an electrically grounded system (voltage at infinity is zero).
However, the charge at infinity may not exactly balance the charge in the
problem region.
6. Verify that Charge is selected, and then click Assign to define the balloon boundary. The
background is ballooned, and balloon replaces NEW next to balloon1 in the Boundary list.
Leave Substrate with a Natural Surface
The substrate is to remain with a natural surface. Therefore, its boundary does not need to be
explicitly defined.
Exit the Boundary Manager
Once the boundaries and sources have been defined, you can exit the Boundary Manager.
To exit the Boundary Manager:
1. Click File>Exit. A window appears, displaying the following prompt:
Save changes to “microstrip” before closing?
2. Click Yes.
You are returned to the Executive Commands window. A check mark now appears next to Setup
Boundaries/Sources, and Setup Solution Options and Solve are now enabled.
