Pathfinder 2015.1

What's New

This version of Pathfinder uses version 1.8.0_05 of the Java VM.

Changes since Pathfinder 2014.3.1208:

• Added dynamic contours / heat maps of occupant data to 3D results
• Added customizable fundamental diagrams to control occupant speed from density
• Improved flow rates through doors to better match SFPE flow rates in steering mode
• Improved occupant movement:
  • Improved acceleration model
  • Made occupants spread according to Fruin spacing diagram
  • Reduced chances of occupants turning 270 degrees to go around a corner
  • Added occupant avoidance of wall / doorway boundary layer
• Added ability to specify comfort distance in terms of occupant queuing density or area
• Made it faster to update camera views / tours in complex models
• Made it possible to hide occupants in the results (useful for displaying contours)
• Changed default comfort distance from 1 ft to .08 m to match SFPE density data as speed goes to zero
• Fixed a bug in SFPE mode that could cause occupants to flow at the wrong flowrate through doors leading out of a stairway
• Fixed a bug in SFPE mode that could allow occupants to fill a room slightly above the maximum density
• Fixed a bug that could cause occupants to go the wrong way through a one-way door
• Added warnings that will appear on simulation startup if an output file is locked by another application
• Fixed a bug that could cause occupants to become stuck if they have a room goal beyond a closed door
• Fixed a bug that could cause occupants to pass through others immediately when they turn around after choosing a different door
• Fixed a bug that could cause an occupant to go through a wall and become stuck
• Fixed a crash that could occur during selection or using of the drawing tools
