CANVAS system and check whether the work is successfully uploaded (by downloading
the file from CANVAS again). All claims on technical problem without strong evidence for
unsuccessful uploading shall not be accepted.
(8) It should be the students’ responsibility to double-check the readability (pdf or docx
format) of the submitted files.
(9) Administration team will not remove or replace student’s submitted assignment in
CANVAS or help students to upload the soft copy of his/her assignments to CANVAS.

FV2204 Computational Engineering – Assignment No.2
(Learning Outcome 4-6) The architectural layout of the 2-stories building is shown in
Figure 1 & Figure 2 as below. The ceiling height of G/F and 2/F is assumed as 5 m and
3 m respectively. The ultimate place of safety is defined at the open area leading to the
open street.

Assume the building has installed smoke detectors to cover the accommodation area
including the corridor and entrance lobby. No sprinkler system is provided for the
building. As a fire engineer, you are required to use the appropriate engineering software
to study the impact of fire and smoke on the occupants under the designed fire scenario.
- You are required to use Fire Dynamics Simulator (FDS) for the below TWO fire
scenarios. You shall describe the main assumptions for designed fire scenarios
including but not limited to the fuel type, fire bed area, building construction,
environmental conditions, etc. and indicate the boundary conditions and fire location
on the layout plan. The simulation time shall be not less than 10-mins for EACH fire
scenario to evaluate the Available Safety Egress Time (ASET) referring to
- Temperature distribution
- Carbon Monoxide distribution
- Visibility distribution
- Radiation heat flux along the egress route

Referring to the FDS simulation results, the time to reaching untenable criteria shall
be summarized to indicate the ASET for the designed fire scenarios. The study shall
provide model assumptions and discussion on the simulation results with at least 150
words and captured screenshots by Smokeview at every 100 seconds till the end of
the simulation. The student shall propose appropriate improvement measures by
provision of sprinkler heads, additional opening as smoke vents, mechanical smoke
extraction, or other solutions to increase the ASET with the 2
nd round of evaluation
using FDS simulation.

- You are required to use the evacuation model FDS+Evac to study the occupants’
evacuation of the whole building till all the occupants reaching the ultimate place of
safety for the following TWO evacuation scenarios. You shall state the main
assumptions with necessary calculation/analysis for the occupants’ characteristics
such as no. of occupants in each room/floor, pre-movement time, unimpeded walking
speed on horizontal floor or downward stairs, etc. for EACH scenario. Discussion on
the evacuation simulation results shall be summarized to indicate the RSET by
room/floor/building with at least 150 words and captured screenshots by Smokeview
at every 30 seconds till the clearance of the whole building.
a. Fire Drill Mode: No fire is involved. All the exits and staircases are available
during the evacuation. Detection time is assumed as 0s.
b. Evacuation Scenario: Left staircase will be blocked due to the fire spreading out
from the lecture room at 2/F. All the occupants at 2/F must use the right staircase
to reach the G/F. Detection time is assumed to be 30s
