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
