Release Notes

This release adds new Elevators operation types, adds UI and performance improvements, and fixes some bugs.

This version of Pathfinder uses version 11.0.16_8 of the OpenJDK Java VM.

Changes since Pathfinder 2022.3.1207:

UI Improvements and Changes
  • Added missing icons in the Model menu.
  • Changed to a two icon wide tool palette for consistency with PyroSim.
  • Replaced render options toolbar buttons with a dropdown.
  • Added lightbulbs to filter action icons.
  • Removed delete toolbar action.
  • Removed separators between combo boxes and button groups.
  • Matched the order of menu items.
  • Added missing menu icons.
Elevators
  • Added different modes of operation for Elevators. The EVAC elevator type will perform egress elevator operations, and the new SCAN elevator type will perform general-purpose elevator operations.
  • Added a new Target Floor field for the Goto Elevators Action, which will dictate the floor that occupants using the action will attempt to discharge at.
Monte Carlo
  • The monte carlo case generator now provides a profiles parameter for occupant profile reassignment.
Bug Fixes
  • The current expansion state of a group node is now preserved when dragging and dropping an item into the group.
  • Fixed a bug that broke Monte Carlo results plotting for internationalized versions
  • Fixed a crash that could occur when opening legacy models if the Behaviors group or Profiles group is expanded.
Other Improvements and Changes
  • Renamed Jam Time and related outputs to Congestion.
  • Updated Congestion (formerly Jam Time) calculation to compare the average velocity over a trailing time period to the threshold. This prevents resetting Continuous Congestion values due to small movements.
  • Improved snapping for planar geometry tools (e.g. rooms, occupant sources, measurement regions) when drawing in the Perspective View.
  • Improved distributions of certain random choices made by occupants over time, such as the choice of behavior when using a change behavior action or whether to choose an attractor.

Changes to Results:

Quantity Plotting
  • Added the ability to plot quantities related to a room, door, or occupant by right clicking them in Results.
UI Improvements and Changes
  • Added floor tool-bar above navigation view.
  • Removed separators between combo boxes and button groups.
  • Matched the order of menu items.
  • Added missing menu icons.
Bug Fixes
  • Fixed a bug where background images cannot be shown.
  • Fixed some screen artifacts when using SMAA 2x or motion blur.
  • Fixed a crash that could occur when trying to load a corrupt s3d file for fire/smoke. Results will now try to skip corrupt data.
  • Fixed an issue where the lower-left axes exhibited aliasing when using one of the SMAA anti-aliasing options.
