winget install --id Thunderhead.Pathfinder.2026About Pathfinder 2026
Pathfinder delivers agent-based simulation through an intuitive interface to output clear and detailed results. Each occupant in a Pathfinder model is aware of their surroundings and constantly recalculates their next step based on present information. These decisions are informed by academic research and validation testing. This process allows the Pathfinder simulation engine to model realistic human behavior. 1. Thunderhead Engineering partners with leading researchers and hosts premier events to promote further...
What's new in 26.1.0211
Travel Distance Contours Pathfinder 2026.1 introduces new Travel Distance Visualization Contours that provide clear, post-processed views of how far Occupants traveled during a simulation. The new contours are calculated after the simulation completes, using the known total travel distance of each Occupant. The resulting values can be visualized either as a color-mapped contour overlaid on the geometry or by coloring individual Occupants themselves. Pathfinder includes two related contour options: Travel Distance, which shows the total distance traveled, and Travel Distance Remaining, which represents the distance an Occupant still had to travel to reach an exit. Figure 1. Example Travel Distance Remaining Contour These contours can be used to gain deeper insight into movement efficiency and spatial performance within a model. By examining Travel Distance, users can identify long or inefficient paths, potential circulation issues, or areas where design changes might reduce walking distances. The Travel Distance Remaining contour can help highlight locations where Occupants are still far from exits at specific simulation endpoints, supporting evaluations of egress design, exit placement, and overall building layout effectiveness. You can read more about Travel Distance and Travel Distance Remaining on the Occupant Contours and Occupant Coloring pages of the Results 2026.1 Documentation. Occupant Vision Contours Pathfinder 2026.1 introduces new Occupant Vision Visualization Contours that provide a powerful way to understand what parts of a model are actually seen by Occupants...
