==Running a SBR Analysis==
At this time, you are ready to run a quick SBR analysis of your propagation scene and visualize the received power coverage map. Since a But keep in mind that in indoor propagation scenes, an extremely large number of receivers are located inside reflected rays may be produced due to successive bounces from all the buildingwalls, ceilings and floors. If you need to freeze don't limit that maximum number of ray bounces, the box object to see the coverage map insidesimulation time may increase significantly. Open the simulation run dialog and click the {{Notekey| You can freeze individual objects or groups Settings}} button next to the simulation engine type drop-down list. This opens up [[EM.Terrano]]'s Ray Tracing Engine Settings dialog. At the top of objects from their contextual menuthe dialog, you will see a box labeled '''Max No. Freezing an object shows Ray Bounces''' that has a wireframe default value of its geometry and doesn't let you select, mouse-over or highlight the frozen object10. Reduce this value to N<sub>ref</sub> = 4.}}

Run a quick SBR analysis of your propagation scene and visualize the received power coverage map. Since a large number of receivers are located inside the building, you need to freeze the box object to see the coverage map inside.
{{Note| You can freeze individual objects or groups of objects from their contextual menu. Freezing an object shows a wireframe of its geometry and doesn't let you select, mouse-over or highlight the frozen object.}}
