Fire dynamics simulators are computer programs that model the spread of fire, helping predict how it will react to different scenarios. They divide fires into small sections, incorporating factors such as materials, temperatures, fuel sources, and wind. These programs rely on computational fluid dynamics and data from previous fires. Firefighters, manufacturers, and code developers use them for training, research, and design purposes. The most widely used program is the free “Fire Dynamics Simulator” by NIST, which is used to study fire and create visual representations of the data.
A fire dynamics simulator is a type of computer software designed to model the spread of fire. These modeling programs allow users to predict how fire will react to different scenarios, which could make it easier to fight both buildings and wildfires. Firefighters, manufacturers, and municipal code developers rely on fire dynamics simulation programs for training and research purposes. This software not only serves as an educational and investigative aid, but also helps companies design and test new fire protection systems.
Fire simulators divide a fire into small, manageable rectangles or squares. This grid system allows users to analyze a single section of the fire or view the entire scenario as a whole. Some of these programs also provide 3D visual modeling to make it easier to explain the effects of fire to those with less technical knowledge. A fire dynamics simulator incorporates factors such as materials, temperatures, fuel sources and wind to predict how a fire will react. Some even allow users to modify these features to study the fire under different types of conditions.
These programs rely on computational fluid dynamics to predict how heat and flames will spread under a given set of conditions. They also incorporate math, science and engineering principles to model wildfire scenarios. These programs rely heavily on data generated from previous fires, which is used as predictors of future fire emergencies.
One of the most widely used fire modeling programs was created in 2000 by the US National Institute of Standards and Technology (NIST). This free program is distributed under the name “Fire Dynamics Simulator” and is widely used by firefighters and manufacturing companies to study fire. NIST also provides a companion program known as Smokeview, which provides a visual representation of the data created by the fire dynamics simulator. Other visual programs and complementary software systems are also available from other sources.
A fire dynamics simulator serves as an invaluable training tool for firefighters, who are able to save lives and protect property based on what they learn from these models. These programs also help keep firefighters safe as they work around the fire. Investigation and insurance teams rely on this software to recreate a fire during an arson or other crime. Code developers use this software to determine the most effective building designs and fire protection measures. Finally, manufacturers use these programs to refine fire protection systems such as sprinklers and smoke detectors.
