Simulex also attempts to simulate overtaking, body rotation, side-stepping, and small degrees of
back-stepping as it moves occupants throughout the building.
Output: The output consists of a 2-D visualization of the evacuation. Also, the following is
provided as output by Simulex:
• General overview of the building input: including number of floors in the building, number
of created staircases, number of exits in the building, number of created links, and the
number of occupants evacuating from the building.
• Floor input: initial number of occupants placed on that floor, link positions on the floor plan
and connections to the corresponding staircases, and positions of the exits on that floor (if
any).
• Stair input: number of occupants initially located in the stair and the link positions and
corresponding connections to the floor plans.
• Overall evacuation time of all occupants reaching the exits
• Number of people passing through all exits over 5-second intervals
• Number of people through each exit (1 and 2) over 5-second intervals
