This example considers the application of analyzing a Wi-Fi router in a building.
Adding Material Properties
To add material properties to the ceiling, doors, floor, windows and walls, the materials first need to be loaded from the Material Database. A property can be defined and assigned when the material is loaded into the model.
Applying Material Properties to the Model
Apply material properties to the floor, ceiling, doors, walls and windows.

    This example considers the application of analyzing a Wi-Fi router in a building.
    - Example Overview
      This example shows how to define and set up a radio coverage solution in Altair SimLab. The model is a single-storey building with doors and windows, solved using the Dominant Path model (DPM). The model is solved and the results are displayed.
    - Topics Discussed in this Example
    - Example Prerequisites
      Before starting this example, ensure that the system satisfies the minimum requirements.
    - Launching and Configuring SimLab
      Open SimLab and configure SimLab to only show the tools relevant to the selected solution.
    - Navigating the Graphics Window
      The graphics window is used to display and interact with the model. You can zoom, rotate and pan a 3D model using the keyboard, mouse, or a combination of both.
    - Defining the Sketch Plane
      Set up the XY plane as the sketch plane. The floor plan will be drawn on this plane.
    - Setting the Model Units
      Change the model units to meters, kilograms, and seconds.
    - Creating the Building Geometry
      Use 2D sketches to define the building floor plan, doors, and windows. The sketches are realized as single sheet bodies to create the building geometry.
    - Adding Material Properties
      To add material properties to the ceiling, doors, floor, windows and walls, the materials first need to be loaded from the Material Database. A property can be defined and assigned when the material is loaded into the model.
      - Loading Materials from DataBase into Model
        Select the material from the database and make it available by pulling into the model.
      - Applying Material Properties to the Model
        Apply material properties to the floor, ceiling, doors, walls and windows.
    - Hiding Selected Objects in the Graphics Window
      To make placing the antenna in an upcoming topic easier, hide the ceiling for now.
    - Defining a Radio Coverage Solution in SimLab
      Create a radio coverage solution for the model (bodies).
    - Adding an Antenna
      Add a Wi-Fi antenna to the model.
    - Adding a Prediction Plane
      Define a prediction plane where the results are to be predicted when running the WinProp Solver.
    - Specifying the Propagation Model - DPM
      Select the Dominant Path Model (DPM) as the computation method.
    - Defining the Result Requests
      Specify the predictions to be computed.
    - Solving the Model
      Compute the propagation for the antenna to obtain the prediction results.

Applying Material Properties to the Model

Apply material properties to the floor, ceiling, doors, walls and windows.

Assign the material brick to the walls with a thickness of 10 cm.
1. In the Assembly Browser, select all the wall geometry.
  
  Tip: Confirm that the wall outlines are highlighted in red to indicate selection.
2. On the Analysis tab, in the Property group, click the Property icon.
3. In the Name field, rename the property to Brick.
4. In the Entity field drop-down list, select Shell.
5. In the Material field drop-down list, select Brick.
6. In the table, in the Thickness field, change the value to 0.10 m.
7. Click OK to close the Create Property dialog.
Repeat Step 1 and assign the material wood to the doors with a thickness of 0.005 m.
Repeat Step 1 and assign the material glass to the windows with a thickness of 0.005 m.
Repeat Step 1 and assign the material cement to the floor with a thickness of 0.01 m.
Repeat Step 1 and assign the material plaster board to the ceiling with a thickness of 0.001 m.

Tip: Confirm that the materials are correctly assigned:

View the assigned material properties in the Assembly Browser.
Color the building by material or property by right-clicking in the graphics window and clicking Display in Color > Material or Display in Color > Property.
