Thunderhead Engineering solutions for Fire simulation.
Pathfinder is an emergency egress simulator that includes an integrated user interface and animated 3D results. Pathfinder allows you to evaluate evacuation models more quickly and produce more realistic graphics than with other simulators.
Pathfinder provides support for the import of AutoCAD format DXF and DWG files. Pathfinder’s floor extraction tool makes it possible to quickly use the imported geometry to define the occupant walking space for the evacuation model.
Pathfinder supports two simulation modes. In Steering mode, agents proceed independently to their goal, while avoiding other occupants and obstacles. Door flow rates are not specified but result from the interaction of occupants with each other and with boundaries. In SFPE mode, agents use behaviors that follow SFPE guidelines, with density-dependent walking speeds and flow limits to doors.

Pathfinder’s floor extraction tool makes it possible to quickly use the imported geometry to define the occupant walking space for the evacuation model. PyroSim or Fire Dynamics Simulator (FDS) models can also be used to extract the walking space.
If you have a blueprint, it can be imported in GIF, JPG, or PNG format and then used as a background to help you rapidly draw your model directly over the image.
