This update adds import support for FBX and OBJ files and adds detailed occupant exposure tracking based on FDS output. Read More...

Shopping Mall, Switzerland

February 10, 2016

Pathfinder case study by Christian Kohler from Swissi.

This evacuation simulation was conducted as part of a security screening of an existing shopping mall in Switzerland. Defined evacuation routes were simulated with a set pre-movement time to analyze jam times and total evacuation times.  Read More...

Evacuation using Familiar Routes

December 3, 2015
Using Pathfinder, we show how to require some occupants to evacuate using familiar routes. Read More...

Refuge Floor, Firefighters, and Elevators

December 1, 2015
In this example, we show some advanced evacuation features of Pathfinder: a refuge floor, evacuation using banks of elevators, and firefighters in stairs moving against the flow in the evacuation of a high-rise building. Read More...

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...

Training Events in Singapore, October 2015

The event "Best Practices for Fire Simulation: PyroSim and Pathfinder", will be hosted in Singapore at SCDF HQ, 91 Ubi Avenue 4, by our distribution partner Building System & Diagnostics Pte Ltd (BSD). Bryan Klein from Thunderhead Engineering will be presenting. Read More...

Advanced Up/Down Speed Properties

October 13, 2015
In the previous release, fundamental diagram customization added increased control over pedestrian movement by allowing users to define the relationship between speed and density. Pathfinder 2015.2 adds customization for stairs and ramps with independent up or down speed restrictions, and fundamental diagram customization. Read More...

Pathfinder 2015.2.1012

October 12, 2015
This update adds improved movement algorithms for group cornering and counterflow, separate speeds for moving up and down stairs, and import support for AutoCAD 2016. Read More...

Pathfinder: Merging Behavior on Stairs

September 9, 2015
During evacuation using stairs, the geometry of the stairs and landings can change the merging behavior. On the landing, the occupants entering from the floor must merge with the occupants already on the incoming stairs. This post discusses Pathfinder simulations of these effects. Read More...

Import Fire and Smoke Slices into Evacuation Results

July 7, 2015
Slices are results recordings that capture user-defined planar slices of information. This allows the user to spend minimal processing time recording important areas of analysis. Read More...
