Getting Started: A 2D Electrostatic Problem Display the 2D Boundary/Source Manager To display the Boundary Manager: • Click Setup Boundaries/Sources. The 2D Boundary/Source Manager appears. Boundary Manager Screen Layout The Boundary Manager is divided into several sections, each displaying information about a � particular property of the model and its boundaries. Boundary Each time you choose one of the Assign>Boundary or Assign>Source commands, an entry is added to the Boundary list on the left side of the window. When you first access the 2D Boundary/ Source Manager, the Boundary list is empty. Display Area The geometric model is displayed so that you can select the objects or edges to be used as � boundaries or sources, using the Edit>Select commands. Boundary/Source Information The area that appears below the geometric model allows you to assign boundaries and sources to objects and surfaces and display the parameters associated with the selected boundary or source. 5-6 Defining Materials and Boundaries
Types of Boundary Conditions and Sources Getting Started: A 2D Electrostatic Problem There are two types of boundary conditions and sources that you will use in this problem: Balloon boundary Can only be applied to the outer boundary, and models the case in which the structure is infinitely far away from all other electromagnetic sources. Voltage sources Specifies the voltage on an object in the model. The electric scalar potential, �, is set to a constant value, forcing the electric field to be perpendicular to the objects’ surfaces. You must assign boundary conditions and sources to the following objects in the microstrip � geometry: Left microstrip This surface is to be set to 1 volt. Right microstrip This surface is to be set to –1 volt. Ground plane The grounded reference. This surface is to be set to zero volts. Background The outer boundary of the problem region. This surface is to be ballooned to simulate an electrically insulated system. Before you identify a boundary condition or source, you must first identify the surface to which the condition is to be applied. You will select and then assign boundaries and sources for the following objects: • left • right • ground • background There are several ways to select objects’ surfaces, but in this sample problem you will select each object individually. As a result, the object’s surface will be selected. There are also several ways to assign values to surfaces. The sample problem illustrates two ways to do so. Defining Materials and Boundaries 5-7
