Pyrosim Slideshow

PyroSim is a graphical modeling tool built around the Fire Dynamics Simulator (FDS) from NIST that allows users to create large, complex fire models more quickly and easily compared to manually creating FDS input files. Key features include the ability to import CAD files and sketch models using floor plans as guides, draw and arrange geometry using interactive tools, automatically decompose geometry for FDS, and generate complete FDS input files from the PyroSim model.

Powerful Fire Modeling


Create large, complex fire models quickly and easily with PyroSim. You can develop advanced simulation models in a small ll f fraction ti of f th the ti time required to manually create FDS input files.

Draw Using Floor Plan Guides


Accurately sketch model geometry using background images. images You can quickly create fire model geometry directly from floor plan data without repetitive coordinate entry.

Import CAD Geometry


Import geometry from AutoCAD DXF files. PyroSim can import 2D and 3D geometry files. Geometry can be used as a background guide and extruded to create walls.

Extrude 2D Objects

Import 3D Geometry

Represent Complex Objects


Import arbitrary geometry and convert into blocks for FDS input.

Interactive Drawing Tools

Graphical tools for drawing geometry in 2D and 3D let you quickly create objects with the help of instant visual feedback. A variety of different tools are available for fast creation and editing of geometry with full undo/redo capability.

Move and Copy Objects


Save time by moving and copying objects to new locations. You can move, copy, scale, and replicate all geometry in your model to quickly accomplish repetitive tasks and leverage existing g models.

Rotate Objects

You can also Y l rotate t t geometry in PyroSim to quickly arrange geometry p and create circular shapes.

Automatic Geometry Decomposition


PyroSim automatically breaks up complex di diagonal l and d curved d geometry into the gridaligned blocks required for FDS input. p

Model Organization

Save time and simplify edits to your large models with tools to group similar geometry and manage multiple floors.

Simplified FDS Input

Organized input forms simplify the specification of fire and material properties and significantly reduce errors.

Automatic FDS File Creation


All FDS input records are automatically generated from the PyroSim model, so you don't have to remember FDS input file syntax or spend time entering hundreds or thousands of lines of text. text

Integration with FDS


Run FDS seamlessly y from within the PyroSim user interface and quickly interpret results using PyroSim and Smokeview.

High Quality Graphics

Create realistic presentation graphics with support for textures, advanced shading, and fly-through modes.

International Versions

Simulation Software for PerformancePerformance-Based Design

Graphical p User Interface for FDS
