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...
