Freezing HRR in PyroSim

November 11, 2015

A common strategy when modelling a fire with sprinklers is to assume the fire will be held at a constant heat release rate (HRR) when the first sprinkler activates. This post shows how to do this by automatically “freezing” the HRR at a constant value when a sprinkler activates.


Improved Cornering in Pathfinder 2015.2

October 21, 2015
Changes in the movement algorithms for Pathfinder 2015.2 have improved the cornering capabilities of occupants in high density, wide corridor turns. The cornering behavior seeks to steer agents so that they can take wide turns as part of a group without cutting in front of each other. Read More...
