Fenix+ 3 application allows you to display evacuation flow density maps for all floors in the building. Using these maps, you can learn the dynamics of human flow density on floors during evacuation.
To display a density map for a certain floor, select a desired floor in the scenario browser and then click 
button in the Density map section on the visualization panel.
Before you create evacuation flow density maps, run the evacuation simulation in the scenario.
A typical evacuation flow density map is illustrated in the picture below.
You can estimate changes in the density of evacuation flow from low to high using color indicator: dark blue (unimpeded evacuation flow) - light blue - green - yellow - red (dense evacuation flow).
You can configure density map parameters. For this, click the 
button in the Density map section on the visualization panel.
As a result, the following window opens.
In the BG discard field, specify the range of the blue-green spectrum, which must not be displayed on the maps.
In the Cell size field, specify the cell size, which is used when creating density maps.
We recommend you to change the cell size when you configure density map parameters only for stairways.
In the Algorythm field, select the algorythm to create density maps. It is recommended to use the With visibility option, which is selected by default. If the Nearest opton is selected, the density maps are created with the accent on the places where the evacuation flow is highly dense.
To create density maps for landings, select the Transfer from landings to stairways.
In the application, you can also display a graph of the maximum human flow density. For this, view the evacuation modeling results. For details, see Evacuation Simulation Results, select the building from the list of exits, and then switch to the Density, m²/m² tab at the top of the graph.
