Pathfinder 2009.1.0417

Released on April 17, 2009

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.
