Proximity Analysis and the Thunderhead development process

April 29, 2021
The upcoming release of Pathfinder Results version 2021.2 will include a Proximity Analysis feature based on the paper EXPOSED: An occupant exposure model for confined spaces to retrofit crowd models during a pandemic by Enrico Ronchi and Ruggiero Lovreglio. In the paper Enrico and Ruggiero lay out a method to create metrics that measure occupant ... Read More...

Queues in Pathfinder 2021.2

April 23, 2021

Queues introduce an entirely new concept of occupant movement to Pathfinder which is restricted by pre-determined Paths and waypoints called Services. This will allow users to better simulate behaviors at airports, restaurants, amusement parks, and more.  Read More...

User Experience Improvements to Pathfinder 2021.1

February 23, 2021
Pathfinder will also benefit from feedback from our users. This release focuses on incorporating their suggestions in to our products to improve the user experience. We have made several usability improvements to Pathfinder in the 2021.1 release, some of which are mentioned below. Update: The 2021.1 Pathfinder Release is available now.  Added copy/paste functionality to Occupant Profiles Expanding ... Read More...

Monte Carlo Improvements in Pathfinder 2020.5

November 13, 2020

Since Pathfinder 2018.3, users have been able to take advantage of Monte Carlo simulations through a command line interface. In modeling, the Monte Carlo method is used to randomize inputs across many simulation instances. With a statistical analysis applied, users can create probablistic interpretations of the resulting data sets. It is often used in research and is also required by regulations such as RiMEA. Read More...

Mars Colony Biome Evacuation Analysis by Szymon Matkowski

August 11, 2020
Our support team has been assisting Szymon Matkowski with his recent project based on a feasibility study, completed by a team at Wroclaw University of Science and Technology, of possible layouts and technical solutions for a theoretical base on Mars. The study was part of a competition sponsored by The Mars Society in which the ... Read More...

Social Distance Improvements in Pathfinder 2020.3

August 7, 2020
Pathfinder 2020.3 further enhances the user's ability to model social distance behavior as a method to address pandemic safety. Social Distance has been completely separated from Comfort Distance. Now, rather than Enable Forced Separation in the Simulation Parameters (retained in 2020.3 for legacy files), Social Distancing has its own selection field in the Advanced tab of the Edit Profiles dialog. With this recent development, occupants exhibit less "jostle" or "jitter" while smoothly and effectively maintaining distance. Read More...

Change Profile Dynamically with New Behavior Step

November 19, 2019
Coming soon in Pathfinder 2019.3 we will see a new Behavior step that allows occupants to dynamically change their Profile. A similar feature was added previously where occupants could change their behavior. The profile contains the occupant’s characteristics such as speed, door choice, and various settings related to interacting with other occupants in the model.  You ... Read More...

Save Settings for Results Visualizations

October 30, 2019
With the most recent release of PyroSim and Pathfinder, the Results tool has a new ability to save the settings and state of the Results Viewer, this newly saved data is known as a Results 'Visualization'. A 'Visualization' is a collection of settings that define which Pathfinder and FDS results are to be loaded and how those results are to be displayed. It also contains information entered by the user, such as views, tours, colorbar settings, time settings, annotations, object visibility, etc. Read More...

Data Visualization through Occupant Colors in Pathfinder 2019.1

June 13, 2019
Pathfinder 2019.1 introduces an additional way to visualize evacuation results through the color of occupants in the model. Occupants can be assigned a dynamic color value based on criteria such as behavior, profile, speed, and more. The video below illustrates many of these options within a single model. Read More...
