Build Stadiums and Theaters with Inferred Stairs

December 9, 2021
Sometimes Pathfinder models include stair access for occupants which are modeled without any of the user-defined stairs tools. In Pathfinder 2021.4 this modeling technique is automatically detected and occupants traversing the stairs now move according to stair behavior appropriate for the determined riser and tread distances. With the inferred stairs feature, Pathfinder users now have more flexibility in creating complex stairs without sacrificing in movement accuracy. Read More...

Occupant Targets add Seat Reservations to Pathfinder

November 12, 2021
In Pathfinder 2021.4 we will introduce a new object for occupant behaviors called a Target. Occupant targets represent a 1-person location which can be reserved by an occupant through a behavior action. This location remains assigned to the occupant even if they temporarily depart, unless a behavior action triggers them to Abandon the target. Targets are an excellent choice for modeling seating for entertainment venues such as stadiums, auditoriums, or theaters as well as waiting lobbies for medical, commercial, or transit locations. Read More...

Attractors Preview for Pathfinder 2021.3

August 6, 2021
Pathfinder 2021.3 introduces Attractors as a brand new way to allow occupants to interact with objectives outside of their main behavior. Perhaps some airline passengers are tempted by a cafe on their way to their gate, museum attendees are swayed to visit the gift shop, or subway commuters have a few spare minutes to use the restroom before their departure. In each of these scenarios, there is some percentage of the population which will be attracted to a secondary objective. Read More...

2021.2 Patch Release – Available Now

May 26, 2021

One of our Reseller Partners identified an issue when dragging items in the navigation view. When this happens, the application freezes and requires a forced shutdown to proceed. This issue was introduced in the 2021.2.0512 release of both PyroSim and Pathfinder. 

We have identified the problem, and have uploaded patch releases that addresses the bug. The updated versions of PyroSim and Pathfinder are available now.

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.
