IFC Import to Pathfinder (and PyroSim)

November 14, 2018
The next releases of Pathfinder and PyroSim will include the capability to import Industry Foundation Classes (IFC) files that describe building data. In Pathfinder, this can significantly speed model creation since it includes automatic extraction of  floors, doors, and stairs. This post demonstrates this feature.  Read More...

Modelling of Pulsing Post-flashover Compartment Fires

November 12, 2018
One poorly understood compartment phenomenon is pulsating fires. Under certain circumstances, pulsing behaviour have been observed in both pre- and post-flashover compartments and have been identified with poorly ventilated compartments. In this paper, a series of small scale post-flashover compartment fires that exhibited sustained harmonic pulsing are simulated in FDS6. Read More...
