Coupling PyroSim Fire Results with Pathfinder Movement

February 14, 2018
We have begun coupling PyroSim fire results with Pathfinder movement. The first major task was to create a Results Viewer that could merge and display PyroSim and Pathfinder results simultaneously. That has largely been completed. We have also completed limited capability to calculate the Fractional Effective Dose (FED) as occupants move through changing CO, CO2, and O2 concentrations. Future development will use PyroSim results to alter occupant movement and decision making within the Pathfinder simulation. In this post, we demonstrate the capability currently available in Pathfinder 2018.1 and PyroSim 2017.2. See the post Manually Coupling FDS and Pathfinder to Respond to Smoke for instructions on how to link fire simulation output with evacuation simulation movement  Read More...

Pathfinder at People Movement and Management Show

July 31, 2017
In July of 2017, Thunderhead participated in the People Movement and Management Show held in Derby, UK. Our goal was to introduce Pathfinder to the people movement audience. Pathfinder was originally developed for emergency evacuation simulation as a companion product to PyroSim, our fire simulator. But we are adding features that will make it possible ... Read More...

Subway Station Passenger Movement using Pathfinder

March 27, 2017
This post demonstrates how to use Pathfinder to simulate movement in a subway station, with trains arriving and departing from the station. A growing list of features not specific to evacuation, such as occupant sources and assisted evacuation, make Pathfinder applicable to a much broader range of pedestrian movement problems. Read More...
