Pathfinder, De Vest Alkmaar by Van Hooft Adviesburo

May 24, 2011

Simulation from the model of "De Vest Alkmaar" by "Van Hooft Adviesburo" with modifications by Thunderhead to test our latest version of Pathfinder. This is a short evacuation demonstration of 2177 occupants, with our latest behavior models.


Script Occupant Movement

April 21, 2011
This system can be used to give individual occupants or groups a sequence of intermediate goals that they will follow during the simulation. Read More...

Pathfinder Case Study, Door Selection

February 16, 2011

Recent Pathfinder development has been, to a large extent, focused on our new Locally Quickest approach to controlling how an occupant moves out of its current room. One of the toughest challenges during this sort of simulator development is identifying what the simulator should do. When we find published research that can be compared to our answers, its exciting and very helpful.


Pathfinder 2011.0.0215 (Beta)

February 15, 2011
This release is an update to the Pathfinder 2011 Beta. This version includes changes that improve local door selection in SFPE mode. Now, occupants estimate queue sizes rather than sample density along proposed local door routes. This queue size estimate is now used in steering mode simulations as well.  Read More...

Pathfinder 2011.0.0210 (Beta)

February 10, 2011

Pathfinder 2011 is now available for beta testing. This version includes our new Locally Quickest path selection algorithm and an improved exit specification model. This version has not been run against our V&V test set and is not recommended for "real world" use.
