Door

You can use the Door tool to place one or several doors in a wall.

You can place a door in a wall that has the shape of the following figures: straight wall, polyline, rectangle, circle, and arc. For more details, see Wall.

To place a door in a wall, the height, width, and lower level of the door must be such that the door completely fits within the wall.

To activate the Door tool, click the button or navigate to Tools | Drawing | Door.

You can also use the* **Alt + D** hot key.

To create a door, do the following:

1. Press the LMB to select a wall, where you want to create a door (the selected wall becomes transparent).
2. Move the mouse pointer to select the desired position of the door in the wall. Press the LMB to “lock” the door in the desired place.
3. If you need to place several doors in the wall, repeat the previous step to create the remaining doors.
4. Press the RMB to deselect the wall (the wall will return to its original appearance).

After the door placement, the tool remains active. You can repeat steps 1-4 to create doors in other walls.

Before the door is locked in place, you can change the location of the base point (edge - middle - edge) used when creating the door in the wall. To do this, press the Space key while placing the door.

You can define door parameters before, after and at the moment you create the door on the scene.

The picture below shows an example of creating a door in a wall. After you select the wall, where you want to create a door, this wall becomes transparent, allowing you to crteate a door in a desired location if an underlay is used.

In Fenix+ 3 application, a door can have the following properties:

• Blocked - people cannot evacuate through a blocked door.

• Fire-proof - dangerous fire factors spread through the door when it is open, and do not spread through the door, when it is closed. The door is equipped with an automatic closing device. For details, see the description of a door with a closer.

• With registering device - the door has a Registering device. The registering device is located in the doorway at the height of 1.7 m from the bottom level of the floor.

• With a closer - the door is equipped with an automatic closing device. This parameter determines behavior of doors during the fire dynamics simulation. See Setting Fire Dynamics Simulation Parameters. The default closing time of the door is not set and can be changed after the door is “locked” in place of the wall. To do this, select the door and specify the desired value in the door properties.

For each door you can specify one or multiple properties. For example, a door can be fire-proof and have the registering device or it can be fire-proof and blocked.

You can use locking doors to change the direction of human traffic flow. It is highly not recommended to lock doors by placing obstacles in doorways as well as in front of them, in the form of other objects, for example, walls, solid bodies. Otherwise, the simulation will end with a Looping status.

For more information on looping, see Problems That May Occur During the Evacuation Simulation.

Doors with different properties are visually distinguishable. The image below shows a graphical representation of doors with various properties in the application. Any door can be marked as With a closer. In this case, a rectangle - “Closer” is displayed in one of the corners of the door.

The application allows to determine the behavior of doors and specify the time for closing doors with closers. For details, see Setting Fire Dynamics Simulation Parameters.

For doors with a registering device, you can change the critical visibility value. For more information, see Registering Device.

For any door in the scenario, you can define the material from which it is made.

If the door does not act as a barrier to the spread of dangerous fire factors, it can be disregarded during fire dynamics simulation. For more details, see Ignoring Objects in Fire Dynamics Simulation.

To make air exchange more realictic during the fire dynamics simulation, the application can consider the penetration of air and combustion products through the imperfections of closed doorways. To do this, select the desired doors and check the box for the Account for leaks option in the door properties. If necessary, change door characteristics used to consider leaks. For this purpose, in the properties of the doors, set the desired characteristic: leakage area, specific gas penetration resistance characteristic or gas penetration resistance characteristic. Then specify the required value. Results will be displayed in Smokeview application. For more information, see Fire Dynamics Simulation Results.
