Creating the Model

Import the protected patch antenna and place the antenna on the back of the helicopter fuselage.

  1. Use the model considered in Antenna Coupling Between Antennas and rename the file.
  2. [Optional] Add a workplane on the back of the helicopter fuselage where the protected patch antenna will be placed. Label the workplane Helicopter_workplane.
    Figure 1. A workplane was added on the back of the helicopter fuselage.


  3. Import the protected patch antenna model from Creating the Model1.
    Note: Protected models can only be imported using Home > Protection > Import Protected Model.
    Figure 2. The protected model was imported and is now located at the origin, below the helicopter.


  4. Align the protected model on the back of the helicopter fuselage using the workplane of the protected model (ProtectedModel1.Antenna_workplane). If a workplane was created in Step 2, use this workplane as the destination workplane (Helicopter_workplane).
    Figure 3. The protected model was placed on the back of the helicopter fuselage.


    Note: Geometry parts that overlap with the protected model results in sections of the simulation mesh being protected and not displayed in the 3D view.
  5. [Optional] For the sake of visualisation, to reduce the overlapping area with the protected model, create a rectangle slightly bigger than then the protected model and union with the helicopter model. This will reduce the area of protected mesh elements that are not displayed.
  6. Exclude the S-parameter configuration added in Defining Calculation Requests to reduce the runtime.
  7. When the password for the protected model is known, the model can be exposed by entering the password. For this example, the password was set to 1234.
    Figure 4. The protected model was exposed and shows the model details.
