What's New

This is a major release of PyroSim.

This version adds import support for Autodesk DWG files and improves import support for DXF files. This version also adds a suite of new visual editing features. Highlights include: precise keyboard entry; pushing and pulling for selected object faces; surface "painting" tools for obstructions and vents; and improved snapping against meshes, objects, and angle constraints. For a complete description, please read the new Drawing in PyroSim chapter of the PyroSim Manual.

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).
