This version of PyroSim is designed for FDS version 5.5.3 and Smokeview version 5.6. It uses version 1.6.0_31 of the the Java Runtime Environment.

Major changes since PyroSim 2012.1.0312 (beta) include:

  • PyroSim now has several new right-click menu options to split, merge, and refine meshes.
  • PyroSim now has a graphical tool to split a single mesh into multiple meshes.
  • The FDS Simulation dialog is now modeless, allowing the user to stop or cancel a simulation before exiting PyroSim in the event of a crash.
  • Gravity can now be specified as a function of time or the x-coordinate.
  • Greatly improved PyroSim’s performance when snapping the cursor to geometric objects.
  • Added support for particle activation (CTRL_ID and DEVC_ID).
  • HVAC name list support can be enabled by installing FDS6 executables and running PyroSim with the flag: -J-DHVAC
  • Objects in FDS input files specifying their color as “INVISIBLE” will no longer be imported as opaque.
  • Updated the Java Runtime Environment (JRE) shipped with PyroSim to version 1.6.0_31. This fixes a bug that prevented PyroSim from opening files located on MicroSoft Distributed File Systems (MS-DFS).
