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 development of pedestrian movement understanding. 2. We validate and publish our own tests of Pathfinder against research data to ensure our tool can be trusted. Pathfinder scales to the size and complexity of your project. Simple experiments can be setup in minutes. Pathfinder also pushes past the limits of other tools with Monte Carlo sensitivity analysis, smoke contaminant exposure, social distance modeling, and more. Thunderhead Engineering supports you every step of the way. Whether you want in-depth training or self-taught materials, you can learn performance-based design modeling with greater efficiency and proficiency. We design our software for anyone to learn, and our customers are delighted when our support team helps them succeed.
What's new in 25.1.0826
What's New This release adds a lot of improvements for Scenario based workflows, alongside a flurry of User Experience Improvements. This version of Pathfinder uses version 21.0.2+13 of the OpenJDK Java VM. Monte Carlo UI Pathfinder's old Monte Carlo utility has now been moved in to the Pathfinder User Interface. Creating tens, hundreds, or even thousands of variations of your movement models, complete with randomizations of Occupant positions, Profiles, and Properties, has never been easier. The new Monte Carlo Parameters UI allows you to easily control all of these variables. Monte Carlo variations are also created for each Scenario in the model, making it even easier to analyze Occupant behavior in your movement space. Create multiple randomized variations using the Monte Carlo Paramters dialog. Running these variations is also seamless. Any variations specified in the Monte Carlo Parameters dialog are run automatically when you click Run Simulation. Run multiple Monte Carlo variations with the click of a button. You can read about these changes in the Monte Carlo chapter of the Pathfinder User Manual. Pathfinder 2025.1 also includes changes to Results that make viewing the Results of multiple Monte Carlo variations much easier. See more about those changes in Scenarios and Variations Support. Improved Scenarios This release makes Scenarios even easier to set up. Prior releases of Pathfinder required that you select Object properties to customize using the Scenario Setup dialog. This is still present, however Pathfinder 2025.1 streamlines this process by allowing you to control the customization of Object properties by shift-clicking them with a Scenario active. Shift-clicking to enable/disable object property customization in a Scenario. This feature makes setting up your Scenarios even more of a breeze. You can read about these changes in the Customizing Property Shortcuts section of the Pathfinder User Manual. Pathfinder 2025.1 also includes changes to Results that make viewing the Results of multiple Scenarios much easier. See more about those changes in Scenarios and Variations Support. User Experience Improvements Pathfinder 2025.1 also contains a long list of other User Experience improvements. PDFs as Background Images PDF files can now be imported for use when drawing your Pathfinder geometry. The process to import these files is the same as for importing Background Images. …
