What's New

Pathfinder first commercial release.

Thank you very much to our beta testers who helped identify the issues resolved below.

Improvements over the Previous Release:

  • The Users Guide, Examples, and Technical Reference have been updated to represent the current version of Pathfinder.
  • Created a Getting Started document to help introduce new users to Pathfinder.
  • The default value for "Max Room Density" (SFPE mode only) has been lowered from 3.55 pers/m^2 to 1.88 pers/m^2. The original value approximately the maximum possible fill, the new value is D[max].
  • The "runtime visualization" is now only available from the Run Simulation dialog (click Debug).
  • Increased the size of the recently opened files list (from 4 to 10).
  • The busy cursor will now appear during several long actions that previously could cause the software to appear frozen.
  • When occupants are drawn as disks or cylinders, an inset triangle will now be drawn to indicating the facing direction.
  • In the 3D results, it is now possible to view all floors of a building simultaneously in a tiled layout.
  • Merged the 2D and 3D floor extraction tools. The 2D Z-based floor extraction dialog has been removed.
  • Time history plots can now be viewed with a 5 time step (output) moving average.
  • Fixed a bug in the steering mode calculation for movement speed on stairs. This fix will cause occupants to move more slowly on stairs in steering mode simulations.
  • Added additional logging for crashes. Crash logs will usually be created in your simulation model directory or home directory (if unsaved).
  • Fixed a bug that caused Pathfinder to crash while drawing doors.
  • Fixed a bug that prevented Pathfinder from saving or running correctly when the simulation contained a large number of floors (50+).
  • The copy/transform tool will now append "(Copy n)" to the name of copied objects.
  • Simulations can now be resumed from snapshot even if the simulation folder has changed.
  • Fixed a tolerance bug that was causing occupants to become stuck.
  • Fixed several bugs related to movement across hilly mesh surfaces.
  • Simulation CPU time is now included in the summary results file.
  • Fixed a tolerance bug that caused the simulation to become stuck when an occupant arrived very near an exit door.
  • Removed the option to view occupants as spheres.
  • Closing the simulation dialog will now prompt to save a simulation snapshot.
  • Fixed a bug that caused occupant now to exit if they unintentionally crossed an exit door.
  • Fixed a bug that could cause agents to become stuck when rounding corners or when traversing "skinny" triangles.
  • In the Simulation Parameters, for SFPE-mode simulations, renamed the "Collision Handling" option to "Add Basic Collisions."
  • Fixed a bug that caused Pathfinder to crash when changing the View mode to "View as People" after zooming in.
  • Fixed a bug in the undo system that was interfering with room deletion.
  • When splitting rooms, the larger room will now retain its color.
  • Fixed a bug that caused the door tool to incorrectly "lock in" for thin doors.
  • Fixed several bugs that could prevent the Add Occupants action from correctly filling under-sized room with a smaller group of occupants.
  • Re-selecting the current floor via the Floors box will now cause the current floor to be shown.
  • In the 3D results, improved the appearance of the playback controls.
  • Live video recording will no longer offer AVI as a format option.
  • Live video recording will now use variable bit rate encoding.
  • Modified the screenshot and video recorder subsystems for improved hardware compatibility.
  • Fixed a bug that was causing tiny mysterious boxes to appear in text fields on computers with limited font support.
  • Fixed several bugs that could cause SFPE-mode simulations to become stuck in crowded, counterflow situations.
