Requesting a Near Field Boundary

Add a near field boundary request to the model. This type of request allows you to define a cuboidal near field request where the request points are located on the surface of the cuboid, but you have the option to exclude specific surfaces (faces).

Figure 1. An example of a Cartesian boundary near field request with only the +N surface and -V surface included (faces shown in blue).


  1. On the Request tab, in the Solution Requests group, click the  Near Fields icon.
    Figure 2. The Request Near Fields dialog.


  2. Under Definition method, from the drop-down list, select Cartesian boundary.
  3. In the , select one of the following:
    • To specify the start and end points and the number of field points, select Specify number of points.
    • To specify the start and end points and the increment between points, select Specify increments.
    Tip: The actual end point (depends on the start point, the number of field points and increment) may not coincide with the specified end point.
  4. Under Boundary surface, click the applicable button if you want to exclude a surface from the Cartesian boundary near field request. Click on one or more of the following to exclude:
    • -U: Exclude the surface in the negative U direction.
    • +N: Exclude the surface in the positive N direction.
    • +U: Exclude the surface in the positive U direction.
    • -V: Exclude the surface in the negative V direction.
    • -N: Exclude the surface in the negative N direction.
    • +V: Exclude the surface in the positive V direction.
  5. [Optional] Select the Sample on edges check box to disable sampling on the edges of the Cartesian boundary.
  6. In the Label field, add a unique label for the request.
  7. Click to request the near field result and to close the dialog.
