This version of PyroSim is designed for FDS version 6.5.1 and Smokeview 6.3.9. It uses version 1.8.0_101 of the Java VM.

Changes since PyroSim 2016.1.0425:

  • Updated FDS from version 6.4.0 to version 6.5.1 (see FDS release notes).
  • Updated Smokeview from version 6.3.6 to version 6.3.9 (see Smokeview release notes).
  • Updated the Java VM from version 1.8.0_60 to version 1.8.0_101 (see Java release notes).
  • Time history plots can now be refreshed during a running simulation.
  • In the Edit Meshes dialog, you can now click the cell dimension to specify cell size with a single input.
  • Visibility settings (e.g. Show Slices) are now saved with the PSM file and are restored when a model is opened.
  • MPI error messages that can appear when running parallel simulations have been improved.
  • PyroSim no longer writes hidden obstructions or meshes to the GE1 file used by Smokeview.
  • Mesh boundaries can now be optionally omitted from the GE1 file using a preference.
  • Smokeview units are now initialized to the same unit system used in the PyroSim model.
  • Statistics regions based on a mesh are now defined as a volume rather than a single point.
  • Fixed a crash that could occur when trying to open CHID_cpu.csv as a time history plot.
  • Fixed a crash that could occur when PyroSim tried to remove duplicate points from an obstruction.
  • Fixed a bug that could cause some non-English strings to appear corrupted in the Additional Records editor.
  • Fixed a crash that could occur when right-clicking a selection of many objects.
  • Fixed a bug that would undo user selection when choosing a Species Quantity for a device.
  • Removed invalid quantities SOLID CONDUCTIVITY and SOLID SPECIFIC HEAT from Animated Isosurfaces dialog.
  • Fixed a bug that caused PyroSim to become unreponsive after stopping an FDS simulation.
  • Fixed a bug that made it impossible to disable groups of HVAC objects.
  • Fixed a crash that could occur when importing a corrupt image.
  • Fixed a bug that prevented smokeview from rendering images.
  • Fixed a bug that could lead to HVAC components not correctly responding to controls.
  • Fixed a crash that could occur when launching the File Chooser dialog.
  • Fixed a crash that could occur after deleting objects through the Add From Libraries dialog.
  • Fixed a bug that could make the record preview for statistics collapse to an unusable size.
  • Fixed a bug that prevented users from opening a new model when working with write-protected files.
  • Removed unused Size and From Surface fields from various Tool Properties.
  • Fixed a bug that caused Zone records to not show leaks in the Record Preview.
  • Fixed a bug surfaces could use an invalid combination of RAMP_V and MASS_FLUX_TOTAL.
  • Fixed a crash that could occur when writing or previewing an FDS file containing a deadband control.
  • Fixed a bug that caused manipulations to rotated objects to sometimes be applied to the wrong face.
  • Fixed a bug that caused the state of active reactions to not be restored during undo.
  • Fixed a crash that could occur when pasting a group of reactions into a model.
