PyroSim's design assumes that most users want to use FDS with a single-fuel, "simple chemistry" combustion model. For simulations requiring multiple fuel species, a few extra steps are required. This post demonstrates how to perform a multiple-fuel simulation using PyroSim.  Read More...

PyroSim now installs a new results viewer to further integrate Pathfinder evacuation simulations, CAD model textures, and camera tours designed in PyroSim. Read More...

This release fixes problems with the HydrateResSim user interface, improves Petrel import support, and fixes crashes related to viewing results.  Read More...

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...

This release fixes bugs leading to incorrect output for sources, sinks, and wells.  Read More...

This release includes bug fixes for Petrel grid import and maximum available sources and sinks. Read More...

This version of PetraSim includes updates to the TOUGH2 source code to add support for several new features, with an emphasis on improved support of geothermal simulation. Read More...

The Debug feature in Pathfinder allows users to see detailed real-time information about the occupants, elevators, and other parts of their simulation. Read More...

The new Pathfinder features, including assisted evacuation, occupant sources, and refuge areas, will release soon in the 2016.2 version. Read More...

Circulation movement is often a critical part of the analysis for high occupancy areas with lots of foot traffic. As research and technology improves, engineers are adding non-evacuation investigations to their résumés. Jennifer Wiley, a Fire Protection Engineer at Jensen Hughes, will discuss these other uses for people movement models at the Fire and Evacuation Technical Modeling Conference (FEMTC).  Read More...
