Thunderhead Engineering Pathfinder
In modern buildings – from high-rise buildings, shopping malls to industrial plants – ensuring safe escape in case of emergency (fire, technical failure, natural disaster) is a mandatory requirement.
To evaluate the effectiveness of the system of exits, corridors, stairs and the density of people moving, engineers need tools to accurately simulate human behavior in real time.
That is the reason why Thunderhead Pathfinder was born – the world’s leading software in the field of evacuation simulation and crowd behavior analysis.
Thunderhead Pathfinder is a software to simulate escape and movement of people in buildings, developed by Thunderhead Engineering (USA).
It allows users to simulate the movement of individuals or crowds in emergency situations, helping engineers, architects and safety experts evaluate the escape capacity of buildings before putting them into use.
The software operates based on two main models:
Steering Mode – a realistic behavioral model where each person navigates, avoids collisions and finds the fastest route.
Flow Mode – a model that calculates the speed of movement based on the flow of people, suitable for high-density constructions. See more SCIA Engineer 2026
Features of Thunderhead Engineering Pathfinder
- Simulate real human behavior
- Each individual in the model can have different personalities and reactions – fast people, slow people, hesitant people, people who follow groups.
- This makes the simulation results closer to reality than traditional mathematical models.
- Direct integration with FDS fire software
- Pathfinder integrates perfectly with FDS (Fire Dynamics Simulator), allowing synchronization of fire and movement of people in the same scenario.
- Engineers can see how heat, smoke and visibility affect the speed of movement and direction of escape of people.
- Intuitive interface, easy operation
- The software has an intuitive 3D interface, allowing drag-and-drop objects, editing exit locations and adding people in just a few seconds.
- Models can be viewed from a real person’s perspective or a panoramic camera, which is very useful when presenting or presenting to investors.
- Optimized calculations, support large-scale simulation
- Thanks to multi-core processing technology, Pathfinder can simulate tens of thousands of people at the same time while still ensuring high speed and stability.
- Detailed reports and flexible data export
- After completing the simulation, the software provides:
- Average and maximum escape time.
- Person density chart over time.
- CSV data for processing in Excel or statistical software.
- A model in Pathfinder includes:
- Geometry: building geometry (floor, wall, door, stairs).
- Occupants: people – each individual has its own characteristics (gender, speed, reaction, priority).
- Behaviors: behavior – choosing direction, speed, reacting to smoke, avoiding crowds.
- Routes: moving route, safe assembly area.
- Events: simulate events such as fire alarms, smoke, door closures, elevator shutdowns.
- After running the simulation, the software will produce videos, heat maps and evacuation time charts, serving for technical evaluation and reporting.
- Thunderhead Pathfinder is an indispensable tool in the field of building safety analysis and simulation of human behavior in emergency situations.
- With the ability to handle complex models, simulate thousands of people and directly integrate with fire software, this is the perfect solution to ensure safety for all modern buildings.
- Thunderhead Pathfinder – Simulate people, protect lives, improve safety design.
