cfdlost New Member Steve Gormley Join Date: May 2014 Posts: 3 Rep Power: 12	Hi I have to model an atrium to look at asset times for each level with a 2.5MW fire at the base. I have to have a extraction ventilation system from the roof. I have tried to control it by a smoke detector but cannot seem to get it to work. I have made the domain higher so I can see the smoke leaving the vent. I also have to supply ventilation in through a door. I am newcomer to FDS and am struggling with this for my college work. Many thanks Steve Q4.txt PS. fds5 is what I have been told to use
