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.
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.

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.
