06.Set the Boundary Conditions

We set the boundary condition for the integral path and also set the outer boundary

You need to set boundary conditions
on some parts of model's body (topology).
It varies depending on the analysis.

The boundary conditions are distinguished by name. It is not allowed to assign the same name to the different boundary conditions
 

Procedure

  1. On the [Model] tab, go to



    and click [Select Edge] on the drop-down list at .

     

  2. How to Switch the Object to Select
     

  3. Concept of Body and Topology

 

 

  1. First, select the integral path

 

Click

Highlight

 

Selected

  1. On the right-click menu, select [Boundary Condition]

 

  1. In the [Boundary Condition] dialog box, enter

    Boundary Condition Name: INTEG

    and click .
     

  2. Any name is acceptable.
     

  1. In the [Edit Boundary Condition] dialog box,

    go to the [Electric] tab,

    set Boundary Condition Type: Integral path

    and click .

    Then click to exit the
    [Boundary Condition] dialog box.

     

  2. The integral path is required to set the reference impedance.

  1. We set the outer boundary condition.

    On the [Model]
    tab, go to ,

    and click [Outer Boundary Condition] .
     

 

  1. In the [Edit Boundary Condition] dialog box,

    go to the [Electric] tab, and

    confirm that the Boundary Condition Type is Electric Wall.

    Then click .

    Now the outer boundary condition is confirmed to be Electric Wall.

     

  2. More on the outer boundary conditions

    There are two types of boundaries: the outer and the inner boundaries.
    The outer boundary is the area where a body meets just the surrounding.
    The inner boundary is the area where two bodies are contacting each other.
    For the outer boundary, the electric wall is not so common, even though it is the default.
    "Electric wall" or "conductor wall" is suitable for a shielded model like waveguide. For other cases, "open boundary" will be more suitable.

    For setting, on the [Model] tab, go to then click

    [Outer Boundary Condition]



    The outer boundary condition is explained here.

     

The boundary conditions have been set.
