The Topology component includes the following objects:

  • Wall

  • Solid object

  • Room

  • Door

  • Window

  • Ventilation

  • Slab

  • Hole

  • Stairway (flight, landing)

  • Line

  • Text

  • Registering device

  1. In the left part of the window, select metadata that will be used in a new scenario.

Scenario metadata includes properties of all the objects located on the scene (for example, width, height, lower and upper level, presence of a registering device, material, etc.). When you select metadata for a new scenario, you define properties of the objects that are inluded into selected components.

  1. Click Create.

As a result, a new scenario will be created in the project.

Selecting the Current Scenario

In Fenix+ 3 Classic, a project may contain one or several scenarios. All scenarios, which are included into the project, are displayed in the scenario list in the left part of the program window.

Floor properties

In the opened window, you can change the following parameters:

  • Name — the name of the floor
  • Level (unit: m) — the lower level of the floor
  • Height (unit: m) — the height of the floor

By default the floor height is 3.0 m. The level of the ground floor is equal to 0 m. The level of every successive floor is equal to the sum of the level and the height of the lower floor.

  • The Number of people parameter is used only to display a total number of people on the floor (including rooms) at a specific moment.

  • The Use a specified value for the start time of evacuation (unit: s) — determines the start time of the evacuation for people located on the floor.

To view and edit levels and heights of all floors in the scenario, right-click the name of the building in the project tree and select Floors settings on the context menu.

Floors settings

In the opened window, a list of all floors with their levels and heights will be displayed.

Changing the height of a floor will change the heights of the objects that are located on this floor. Therefore, it is recommended to set the height of the floor immediately after you create it.

Editing a Scenario

To edit a scenario in a project, select it in the scenario list (for more details see Selecting the Current Scenario) and make necessary changes. All changes you make to the scenario are saved automatically.

In Fenix+ 3 Classic, a project may contain several scenarios. If you edit the current scenario and change one of its component, which is also used in another scenario in the same project, a window with a corresponding warning message will open.

Warning message

To introduce changes only to the current scenario, click Yes. A new component (different from the one used in other scenarios) will be automatically created for the current scenario. To introduce changes to all scenarios, where this component is used, click No. In this case, a new component is not created.

To save changes, click .

In Fenix+ 3 Classic, you can configure program settings so that changes you make to a scenario are saved automatically at specific time intervals. For more information refer to General settings).

Undoing And Redoing Actions

For convenience, Fenix+ 3 Classic allows you to undo and redo actions you perform in the scene editor and properties table. This feature applies to creating and deleting objects as well as changing the location, shape and properties of objects on the scene.

While working on a project, the program saves information about the last 10 actions. You can undo not only the last action, but even all of them.

To cancel the last action, press the button.

To redo the action, press the button.

Cancel and Undo buttons in the control panel{width=60%}

Hiding And Displaying Scenario Elements

Fenix+ 3 Classic allows to hide elements in the scenario that you do not need so that only necessary elements are displayed.

By default all scenario elements are displayed. If necessary, you can hide certain elements, groups of elements (for example, stairways) and floors with all the elements located on them.

Hidden elements are not deleted from the scenario. They are not displayed on the scene.

To hide a certain element, locate it in the scenario browser and clear the check box next to its name or right click the name of the element and select Hide. As a result, the selected element will not be displayed on the scene.

To select multiple elements, use the CTRL key.

To display a hidden element, locate it in the scenario browser and select a check box next to its name or right click the name of the element and select Show. As a result, the selected element will be displayed on the scene.

To hide a group of elements of a certain type, in the scenario browser switch to the Component tab, right click the name of a desired group and select Hide. As a result, the selected group will not be displayed on the scene.

To display a hidden group of elements, locate this group in the scenario browser on the Component tab, right click its name and select Show. As a result, the selected group will be displayed on the scene.

To hide a floor with all the elements, locate this floor in the scenario browser and clear the check box next to its name or right click its name and select Hide. As a result, the selected floor with elements will not be displayed on the scene.

To display a hidden floor with all the elements, locate this floor in the scenario browser and select the check box next to its name or right click its name and select Show. As a result, the selected floor with elements will be displayed on the scene.

To hide all elements on the scene, right click the name of the building in the scenario browser and select Hide. to display all hidden elements, right click the name of the building and select Show.

Exporting a Scenario To FDS Input File

In some cases, before running a fire dynamics simulation you may need to use FDS functionality, which is not available in Fenix+ 3 Classic. For this, you need to export a desired scenario to the FDS source data file and make necessary changes to it. After that, you should run a fire dynamics simulation using third-party software.

The FDS source data file does not include information about the evacuation component of the scenario.

To perform export successfully, the scenario shall contain registering devices, the fire source and the calculation area. Otherwise, the export will fail.

To export a scenario to the FDS source data file, do the following:

  1. Open a desired project (for more information, see Opening a Previously Created Project).
  2. Select a desired scenario (for more details, see Selecting the Current Scenario).
  3. Right-click the scenario name and select Export to FDS.

Exporting a scenario to the FDS Source Data File

  1. In the opened window, specify a destination folder where the FDS source data file will be stored and click OK.

By default, the program offers to export the FDS source data file to the folder where fire dinamics simulation results are stored (for more information, see Logical Structure of Project Folder).

When performing the export of a scenario to the FDS source data file, you cannot change the name of the generated file. By default, the name of the generated file is the same as the name of the scenario.

As a result, the FDS source data file will be created.

After you perform the export of a scenario to the FDS source data file, you cannot perform another export to the same destionation folder. If you want to perform another export, you should select a different destination folder.

Deleting a Scenario

If the scenario was created by mistake or you do not need it anymore, you can delete it.

After you delete the scenario, the project will store information about all its components (for more information, see Creating a New Scenario).

To delete the current scenario, follow these steps:

  1. Right click the name of a desired scenario in the scenario list and select Delete.
  2. In the opened window, confirm the deletion.
