PyroSim is a graphical user interface for the Fire Dynamics Simulator (FDS). PyroSim helps you quickly create and manage the details of complex fire models.
PyroSim imports AutoCAD DXF and DWG files. When PyroSim imports a DWG/DXF file, it will treat all 3D face data as obstructions and all other data (lines, curves, etc.) as separate CAD data. The left image of the figure shows the DWG file face data and the right image shows the grid representation that will be used in the FDS analysis.
PyroSim includes tools to help you create and validate multiple meshes.
PyroSim includes support to launch a parallel simulation using MPI. For a single machine with multiple cores or CPUs, parallel processing is an integrated tool and all details are managed for you.
Pathfinder is an emergency egress simulator that includes an integrated user interface and animated 3D results. Pathfinder allows you to evaluate evacuation models more quickly and produce more realistic graphics than with other simulators.
Pathfinder provides support for the import of AutoCAD format DXF and DWG files. Pathfinder’s floor extraction tool makes it possible to quickly use the imported geometry to define the occupant walking space for the evacuation model.
Pathfinder supports two simulation modes. In Steering mode, agents proceed independently to their goal, while avoiding other occupants and obstacles. Door flow rates are not specified but result from the interaction of occupants with each other and with boundaries. In SFPE mode, agents use behaviors that follow SFPE guidelines, with density-dependent walking speeds and flow limits to doors.
