Creating a New Scenario

Creating a new scenario

When you create a project, one new (empty) scenario will be created automatically.

To create a new scenario, follow these steps:

1. Open the New Scenario set-up window by doing one of the following: select Project | Add Scenario from the general app menu; press the button in the control panel; or, press the Ctrl + Q keyboard shortcut.

2. Specify the name of the new scenario in the Name field.

Each scenario in the project must have a unique name.

3. Select components in each group by clicking on names associated with previously existing scenarios. When you select a component group, all of its objects will be added to the preview area, which will show locations of said objects true to the scene they are taken from.

These actions are non-destructive and will not apply to the existing scenes.

4. Down the list, select a metadata set to be used in the new scenario. All selections together will be combined to create a new scenario.
5. Click Create. As a result, a new scenario will be added to the project and will become the active one.

Scenario components

Each scenario consists of three main component groups, and one additional:

• Topological components;
• Evacuation components;
• Fire components.

And, managed as a separate group is Metadata, which carries the object properties and simulation parameters saved for the scenario.

Any object created in the scenario can only belong to one of the main component groups.

All created objects are automatically assigned to the assigned component group.

In the New scenario window, you can hover your mouse over the component in the list to see which scenarios it’s used in.

Topological component

The topological component includes the following object types:

• Wall;
• Roof;
• Solid object;
• Room;
• Door;
• Window;
• Ventilation;
• Floor;
• Doorway;
• Staircase (flights and landings);
• Line;
• Inscription;
• Recorder;
• Detector.

As well as the following object properties:

• Name;
• Material;
• Geometric numerical values (width, height, length);
• Spatial (level and boundaries of an object);
• Transparency;
• Visibility;
• With caption;
• Do not consider in case of fire;
• With registering device.

Evacuation component

The evacuation component includes the following object types:

• Occupant;
• Exit;
• Waypoint.

Fire component

The fire component includes the following object types:

• Calculation area;
• Fire source.

While the “On fire” property can serve as a source of fire necessary for fire modeling, it’s assigned to the object’s metadata.

Metadata

Scenario metadata refers to the properties that affect the behavior of an element most relevant to simulating evacuation or fire dynamics. Metadata does not include the geometric properties of objects.

Scenario metadata includes values set in the Fire Dynamics Simulation Parameters, Evacuation Simulation Parameters, and Risk Calculation Parameters tabs. At the same time, the General Settings of the program are applied to the entirety of your project.

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

• Building:
  • Evacuation start time;
  • Fire alert delay.
• Floor:
  • Take into account the evacuation start time;
  • Evacuation start time;
  • Alert delay.
• Room:
  • Take into account the start time of the evacuation;
  • Start time of the evacuation;
  • Fire alert delay;
  • Take into account the temperature.
  • Temperature.
• Wall, Roof, Solid object, Floor slab:
  • Measure dangerous fire factors on surface.
• Staircase
  • Blocked;
  • Do not take into account in case of fire;
  • On fire;
  • Measure dangerous fire factors on surface.
• Door, Doorway:
  • Blocked;
  • Fire-resistant door;
  • With registering device;
  • With closer;
  • Account for leaks;
  • Leak characteristics;
  • Leak area;
  • Specific gas permeability resistance characteristics;
  • Gas permeability resistance characteristics;
  • Direction.
• Window:
  • Account for leaks;
  • Leak characteristics;
  • Leak area;
  • Specific gas permeability resistance characteristics;
  • Do not take into account in case of fire;
  • In fire;
  • Measure dangerous fire factors on surface.
• Output:
  • Available for M0;
  • Available for M1;
  • Available for M2;
  • Available for M3;
  • Available for M4.
• Fire source:
  • Start time;
  • End time;
  • Specify the maximum burning area;
  • Maximum burning area.
• Ventilation:
  • Type;
  • Air flow;
  • Activation time;
  • Delay time.
• Detector:
  • Threshold value.
• Person, Waypoint, Calculation area, Recorder, Label, Line — no metadata.
