GPGPU enabled CFD simulation for fully coupled fire and evacuation modelling
Traditionally fire and evacuation models are run independently of one another to ascertain two key building safety parameters: ASET (available safe evacuation time) determined by the fire spread; RSET (required safe exit time) determined by the evacuation model. A building can be deemed to be safe …
