CFAST Online was created to quickly and easily run zone model fire simulations in your browser, without installing any software. It can also be used to quickly generate case files, then download a ZIP archive of the results to your local computer.

Many of the CFAST input parameters that are not available in the web interface utilize the default values. For more detailed control over the simulation, select the "Download CFAST output" option from the Simulation Parameters tab to download the case to your local computer.

This website is a frontend for the CFAST zone model (version 6.2.0), which is maintained by the National Institute of Standards and Technology. The results and CFAST case files are for educational purposes only, and any output should be reviewed by a qualified person. The accuracy of the results is not guaranteed in any way.
