Thunderhead Engineering PyroSim

Free Download Thunderhead Engineering PyroSim for Windows PC is a graphical user interface for the Fire Dynamics Simulator (FDS). PyroSim helps you quickly create and manage the details of complex fire models.

Overview of Thunderhead Engineering PyroSim

PyroSim imports AutoCAD DXF and DWG files. When PyroSim imports a DWG/DXF file, it will treat all 3D face data as obstructions and 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 It will use in the FDS analysis.

This program, PyroSim, includes tools to help you create and validate multiple meshes. Multiple meshes allow you to: use parallel processing to speed the solution, conform your meshes to the geometry to reduce the number of cells and solution time, and change the resolution of different meshes to focus on regions of interest.

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. You must define multiple meshes and select Run FDS Parallel from the solution menu.

A complete set of drawing tools is provided in PyroSim that allows you to create your model rapidly. The tools include supporting all the FDS objects, copying and pasting functions, and attaching textures to surfaces.

Any time during the analysis, It can launch the Smokeview program from NIST. This program allows you to view the smoke, temperatures, velocities, toxicity, and other outputs of the FDS analysis. PyroSim also includes support for XY time history plots.
