What's New

This release adds new features and bug fixes.

This version of PyroSim is designed for FDS version 6.7.5. It uses version 1.8.0_265 of the OpenJDK Java VM.

Changes since 2020.5.1118:

  • Added as-you-go undo/redo support for polygon geometry tools
  • The view setting Preview FDS Blocks will now be saved and restored with the PSM file
  • Fixed inconsistency of tooltips
  • Added the ability for the user to change the number of HOLE and OBST records to highlight in the Record View.
  • Fixed a bug that sometimes caused a control description to be unreadable
  • Fixed a bug that can cause a crash when copying table data in Materials Byproducts tab
  • Forced redraw after changing Angled Geometry settings in Simulation Params
  • Fixed incorrect unit for Extinguishing Coefficient in Edit Surface Dialog (Burner)
  • Added the ability to left-click an item in the navigation view and then left click again to rename
  • Added the ability to make a new scenario active when it is created
  • Added a name field to HVAC tool properties
  • Added move/copy mode information for the move, rotate, and mirror tools to status bar
  • Updated Keyboard Shortcut dialog to check for duplicate shortcuts on input, instead of when exiting the dialog

Changes to Results:

  • Added separate colorbar properties for each FDS quantity.
  • Fixed various issues related to specifying colorbar properties in the FDS preferences dialog and occupant contour dialog.
  • Fixed a crash that could occur activating 3d smoke results.
  • Fixed a crash that could occur opening an smvv or pfrv file.
  • Fixed a bug where 3d smoke might be missing from Results.
  • Added a "Social Distance" occupant contour that shows, for each occupant, the distance to the next closest occupant.
  • Improved the "Social Linkage" occupant contour so it more accurately reflects each occupant's value at their location on the contour.
  • Updated the "Social Linkage" contour to properly account for occupant movement groups. The simulation must be run again for this to work.
  • Improved smoke/fire rendering performance when smoke lighting is enabled.
  • Improved double-click functionality of the active view.
  • FDS output data inside obstructions is now hidden from view when obstructions are hidden or viewed as wireframe.
  • Significantly reduced time to open FDS results when there are many associated output files.
  • Fixed a typo in description of Ambient Occlusion.
  • Removed time device dots at the corner of meshes.
  • Added ability to view Mass Fraction in PPM.
  • Fixed a bug where plot axis labels and title might not be centered.
  • Fixed a crash that could occur when hiding occupant paths.
  • Fixed a crash when opening a pfrv or smvv file when coloring occupants by an occupant contour.
