PyroSim——消防火灾模拟软件

PyroSim 是一款用于消防模拟的软件。

PyroSim是一款运用于消防环境设计的仿真模拟设计软件,其主要提供了多种场合的消防火灾救援与防范方案,可以对停车场、商业中心、住宅区等不同的环境进行仿真分析,为用户提供最安全、最稳定的消防系统,软件可以对温度、通风系统、排烟系统进行设计,根据不同的报警参数设置合理的研究方案;PyroSim具有设计领域的专业技术,提供FDS模拟、Merve Altay建模、压力区泄漏建模、FDS燃烧和燃料组分计算器、FDS网格分配给特定的MPI进程等多个设计模块。


PyroSim适用于FDS version 5和SMV(Smokeview)。安装好后安装目录下带有实例文件(SAMPLES文件夹内)。软件本身具体建立模型工具,可导入FDS文件。它的图形用户界面可以用来当作动态消防仿真器。可以对火灾中烟气的温度、毒气浓度和动进行准确预测分析。PyroSim是设计运行于微软视窗操作系统。

Fire Dynamics and Smoke Control

Quickly build Fire Dynamics Simulator (FDS) models with PyroSim.


Powerful Fire Simulation

PyroSim is the leading software for quickly and accurately working with FDS models.


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.

Import CAD 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.


Alternately, a drawing in GIF, JPG, or PNG format can be imported and then used as a background to help you rapidly draw your model directly over the image.

Managing Multiple Meshes

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 of regions of interest.

Integrated Parallel Processing

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. All you need to do is define multiple meshes and then select Run FDS Parallel from the solution menu.


PyroSim can also be upgraded to run an FDS simulation on a network cluster of multiple computers. Before launching a cluster simulation from within PyroSim, the node installer is installed on each computer that will participate. You will now be able to run the simulation on any number of computers.

Multiple Language Translations

Working with our international resellers, native language versions of PyroSim are available in Chinese Simplified, German, Japanese, Korean, Polish, and Russian. We expect that Portuguese (Brazilian) and Spanish will be available soon.


For more information, contact our resellers for your region as listed on the Purchase page of the PyroSim web site.

HVAC Systems

A major new feature in FDS 6 is the integration of HVAC (Heating, Ventilation, and Air Conditioning) systems into the CFD simulation. The HVAC system can transport contaminants and heat through the building. HVAC systems are defined using ducts, nodes, fans, heat exchangers (aircoils), and dampers. All can be edited and visualized in PyroSim.


The HVAC system can model flow independent of any fire analysis. They may also serve as part of the fire protection system for a building when used to exhaust smoke or maintain stairwell pressurization.


Import Existing FDS Models

If you have an existing FDS model, you can simply import it into PyroSim. All the model information will be imported and available for editing and visualization.


This shows an FDS verification model that was imported into PyroSim.


Property Libraries

PyroSim provides libraries of properties that you can customize and import into your current model. This speeds model creation and reduces error. Libraries can include reactions, heat detectors, materials, particles, surfaces, and other model parameters.


Edit all Model Objects Interactively

PyroSim allows you to interactively view and modify properties associated with all objects in a model. This visual feedback speeds model creation and reduces error. Here we see a surface that includes a tangential velocity to simulate a vent louver.


Drawing Tools

A complete set of drawing tools is provided in PyroSim that allow you to rapidly create your model. The tools include support for all the FDS objects, copy and paste functions, and attachment of textures to surfaces.


Smokeview Post-Processing

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