Thunderhead Engineering PyroSim 2011.1.1409 (x86/x64)

PyroSim is a graphical user interface for the Fire Dynamics Simulator (FDS). It is used to create fire simulations that accurately predict smoke movement, temperature, and toxin concentrations during a fire.

Key Features
PyroSim 2011 is a graphical user interface for version 5 of FDS and Smokeview. Some of PyroSim's key features include:
* Edit geometry using floor plan images, angled walls, and other powerful tools.
* Integrated execution of FDS and Smokeview
* Full support for 64-bit operating systems
* Run multi-CPU simulations with a single click
* Import existing FDS4 and FDS5 models.
* Convert FDS4 input files to FDS5
* Import AutoCAD DXF models directly or as background images.
For a list features and bug fixes new in PyroSim 2010, please read the release notes.

PyroSim is designed to run on MS Window operating systems. Apple users have reported success using PyroSim with both VMWare Fusion and Parallels.

Bigger Models with PyroSim 64-Bit Edition
As of PyroSim 2008.2, registered users can take advantage of 64-bit hardware using a 64-bit version of PyroSim. The key simulation components (PyroSim, MPI, FDS) of this version are provided as 64-bit software. This allows access to memory beyond the traditional 3 GB limit in Windows operating systems - making it possible to create fire models with many more cells than with a 32-bit system. The 64-bit version requires a 64-bit computer and operating system.

Verification and Validation
The developers of FDS at the National Institute of Standards and Technology (NIST) use the model verification techniques outlined in ASTME 1355 to ensure the accuracy of the numerical solutions given by FDS. Additional information can be found in Part III of the FDS Users Guide.

FDS was also the subject of a verification and validation study sponsored by the US Nuclear Regulatory Commission and the Electric Power Research Institute. This work compares 5 different simulators based on several fire scenarios.
