Key Features

PyroSim 2012 is a graphical user interface for FDS and Smokeview. Some of PyroSim’s key features include:

• New 3D geometry creation and editing tools.
• Integrated execution of Official NIST versions of FDS and Smokeview
• Full support for 32 and 64-bit operating systems
• Run multi-CPU simulations with a single click
• Run simulations across multiple computers on a shared network (cluster)
• Import existing FDS4 and FDS5 models.
• Convert FDS4 input files to FDS5
• Import 2D/3D AutoCAD DWG, DXF, and STL models.

For a list new features and bug fixes in PyroSim, 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.

To assist users in making informed estimates about the run-time and memory requirements of models with similar properties, please see the page detailing our benchmarking for PyroSim and FDS_5.

Verification and Validation

The developers of FDS at the National Institute of Standards and Technology (NIST) use the model verification and validation techniques outlined in ASTM E 1355 to ensure the accuracy of the numerical solutions given by FDS. Additional information on Verification and Validation of FDS can be found in Volume 2 and Volume 3 of the FDS Technical Reference 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.
