Pathfinder 是由美国Thunderhead engineering公司开发的一个基于人员进出和运动的模拟器。它提供了图形用户界面的模拟设计和执行，以及三维可视化工具的分析结果。该运动的环境是一个完整的三维三角网格设计，以配合实际层面的建设模式。可以计算每个乘员独立运动并给予了一套独特的参数（最高速度，出口的选择，等等)。 Pathfinder可以导入FDS模型，FDS在模拟火灾的同时，可以在相同时间内模拟人员疏散。同步跟踪不仅可以科学地分析出人员疏散的相关数据。这样既直观，又有可靠的数据，还可以分析出人员疏散的最佳时间，减少人员伤亡。
Pathfinder的人员运动模式包括SFPE模式和steering模式。SFPE行为是最基本的行为，以流量为基础的选择意味着人员会自动转移到最近的出口。人员不会相互影响，但是列队将符合SFPE假设。这种模式是基于SFPE消防手册保护工程和SFPE工程指南:人类行为
，利用空间密度，以确定运动速度。steering模式使用路径规划，指导机制，碰撞处理相结合控制人员运动。如果人员之间的距离和最近点的路径超过某一阀值，可以再生新的路径，以适应新的形势。
Thunderhead Engineering Consultants, Inc. has released Pathfinder 2024.2 (1209). This release enhances modeling capabilities in Pathfinder and adds scenarios, allowing for one model to contain multiple variations of a model.
Pathfinder Scenarios
When creating pedestrian movement or evacuation models, you will often desire to create multiple different configurations of a single model. These configurations often involve changes to Occupants or geometry. You might be interested in how Occupants would react to different influences, how changing geometry might affect the flow of Occupants, or what effects changing a Profile property had on Occupant movement. In prior versions of Pathfinder, you would have to make separate model files to investigate each of these configuration changes, adding unnecessary work and increasing file management overhead. Pathfinder 2024.2 simplifies this process with the introduction of Scenarios. Pathfinder Scenarios allows you to create different configurations of a model within a single model file. With Scenarios, you can manage things like geometry changes, profile parameters, Occupant position, and much more.
Pathfinder Scenarios also provides quick visual indications of Scenario changes with color-coded UI elements and a high-level overview of changes for each Scenario.
– Fixed a bug that could cause a crash when selecting multiple triggers with different Awareness Requirements and clicking the <mixed> value for this property.
– Fixed a bug where some objects could reference other objects that are no longer in the model.
– Fixed a bug that could cause a crash opening some models made prior to Pathfinder 2024.1.
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.
