Creating a New Scenario

When creating a project, a new (empty) scenario is created automatically.

To create a new scenario in the project, do the following:

1. Navigate to Project | Add scenario or click the button on the control panel.

You can also use the Ctrl + Q hot key.

A window opens in which you need to select components for the new scenario.

2. In the Title field, enter the name for the new scenario.

Every scenario in the project must have a unique name.

3. In the left part of the window, select components of the new scenario. When you select a component, the preview area displays all the objects included in it, as well as their relative positions on the scene.

Every scenario consists of several independent components. In fire risk calculation projects, the scenario consists of 3 components:

• Topological;
• Evacuation;
• Fire.

When working on a scenario, all its components are created automatically. Any object created in the scenario belongs only to one of the specified components.

The Topological component includes the following objects:

• Wall;
• Roof;
• Solid object;
• Room;
• Door;
• Window;
• Ventilation;
• Floor slab;
• Opening;
• Stairway (flight, landing);
• Line;
• Text;
• Registering device.

The Evacuation component includes the following objects:

• Occupants;
• Exit.

The Fire component includes the following objects:

• Calculation area;
• Fire source.

After you specify all the components for the new scenario, the final appearance of the scene is displayed in the preview window.

4. In the left part of the window, select the metadata to be used in the new scenario.

Scenario metadata refers to the properties of objects placed on the scene that determine the behavior of an element during evacuation or fire dynamics simulation. Metadata does not include the geometric properties of objects.

Depending on the selected set of metadata, objects in the new scenario receive various properties.

Below is a list of metadata for each object in the scenario:

• Building:

  • Evacuation start time.
  • Alarm delay.

• Fire source:

  • Starting time.
  • End time.
  • Specify the maximum burning area.
  • The maximum burning area.

• Door:

  • Is blocked.
  • Fire resist door.
  • With a registering device.
  • With a closer.
  • Consider leaks.
  • Leakage characteristics.
  • Leak area.
  • Specific characteristics of resistance to gas permeation.
  • Characteristics of resistance to gas permeation.

• Exit:

  • Available for M0.
  • Available for M1.
  • Available for M2.
  • Available for M3.
  • Available for M4.

• Floor:

  • Consider the evacuation start time.
  • Evacuation start time.
  • Alarm delay.

• Room:

  • Consider the evacuation start time.
  • Evacuation start time.
  • Alarm delay.
  • Consider the temperature.
  • Temperature.

• Stairway:

  • Is blocked.
  • Ignore in case of fire.
  • On fire.
  • Measure DFF (dangerous fire facrors) on a surface.
  • With a registering device.

• Ventilation:

  • Type.
  • Airflow.
  • Activation time.
  • Activation delay.

• Window:

  • Consider leaks.
  • Leakage characteristics.
  • Leak area.
  • Specific characteristics of resistance to gas permeation.
  • Ignore in case of fire.
  • On fire.
  • Measure DFF on a surface.

5. Click Create.

A new scenario is created in the project.
