PyroSim 2010.2.1114

Released on November 15, 2010

PyroSim now includes FDS version 5.5.3 and Smokeview version 5.6.

For more information on FDS 5.5.3, please read the FDS release notes.

New Changes:

  • Updated PyroSim to match various input file changes since the last supported version of FDS.
  • Added an option to write-protect the current model.
  • Added support for STL file import.
  • The 64-bit version of Smokeview is now bundled with the 64-bit version of PyroSim and FDS.
  • PyroSim will now automatically create a copy of the last successfully opened PSM file. This option can be disabled in the Preferences dialog.
  • Added support for INIT records.
  • The drop-down box used to select gas-phase quantities is now more concise.
  • Fixed a bug that caused PyroSim to crash when the latest NVIDIA driver (v260) is installed and the Threaded Optimization option is set to Auto.
  • Fixed a bug that occurred when trying to create a gas-phase device while using English units.
  • Added a 64-bit OpenMP executable.
  • When importing FDS input files, PyroSim will now correctly read integer values that have been written with a decimal.
  • Particle clouds now support periodic injection of particles.
  • Reorganized the Preferences dialog into multiple tabs.
  • In the Preferences dialog, PyroSim now displays the version of selected FDS executables.
  • In the About dialog, PyroSim now displays the supported version of FDS.
  • In the Simulation Parameters dialog, the baroclinic torque option is no longer reversed.
  • In the Surface dialog, Heat Release Rate was renamed Heat Release Rate per Area.
  • Fixed a bug that caused MPI authorization to fail when using a blank password.
  • Fixed a bug that caused PyroSim to crash after a mouse drag action in the Tree View.
  • Fixed a bug in the EVAC dependency system that suppressed the replacement prompt when deleting in-use records.
  • Fixed some usability issues with the table editors.
  • Fixed a bug that caused Convert to Blocks to crash when converting objects with zero area.
  • When converting solids to blocks, the resulting internal surfaces will match the external surface.
  • Changed the PyroSim launcher. VM arguments are now prefixed individually with -J rather than -vmargs.
  • Fixed a bug that caused certain rotated geometry to display an incorrect surface mapping in the Properties dialog.
  • Convert to blocks, when merging, now takes into account object names and visibility.
  • Updated the defaults for particles as per FDS updates. This prevents FDS crashes when using fuel sprays.
  • When importing FDS5 input files, RGB values between 0.0 and 1.0 are reinterpreted on the 0-255 scale.
  • When PyroSim detects a PSM file was saved with a newer version, it will no longer attempt to open the file.
