New Visualization for Fire, Smoke, and More

September 7, 2016
We are currently developing new visualization for many fire and smoke effects that are needed for both fire and evacuation modeling. Much of this is driven by a need to integrate evacuation results with fire and smoke visualization, along with other representations of FDS data. The intention is to provide an alternative to Smokeview for PyroSim as well as all new capability for Pathfinder. We are aiming to deliver easy to use camera manipulation, high frame rate visuals, and video capture with many options among other features.  Read More...

Comparing FDS results to fire spill-plume calculations in BRE Annex D

August 4, 2016
The BRE guide Design methodologies for smoke and heat exhaust ventilation summarizes the advice available from the BRE Fire Research Station (UK)  to designers of atria and other buildings. Annex D of the BRE document compares different fire spill-plume calculation methods applied to a multistorey shopping mall. We compare Fire Dynamics Simulator (FDS) results to the calculations in Annex D.  Read More...

Assisted Evacuation & Vehicles Preview

July 13, 2016
Our Pathfinder developers have been working on the long-awaited assisted evacuation and custom vehicle features that will make more applications possible. Hospitals, nursing homes, and retirement homes all must accommodate people in wheelchairs, rolling beds, walkers, and more. The staff at these facilities are required to assist their patients or residents during evacuation. However all public ... Read More...

Critical Velocity in Tunnel Fires

May 17, 2016
Merve Altay contacted us with a tunnel model that was experiencing a numerical instability. He was simulating a set of experiments performed to evaluate the critical velocity in a tunnel fire. Answering his question eventually led to improvements in FDS and a better understanding of user applications of PyroSim/FDS.  Read More...
