It's free to download and try, with a low-cost personal license ($39, unchanged for 15+ years) for continued full-featured use - '''free for .edu (student/education) users'''; see [https://burnsim.com/Download.asp the download page] for details. This wiki documents '''BurnSim 4''', the current cross-platform (Windows, Mac, Linux) rewrite of BurnSim, and covers general topics related to experimental solid propellant motors: propellant characterization, motor testing, data acquisition, and more. Still running BurnSim 3? Its interface differs substantially from what's shown below - see the [[:Category:BurnSim 3 (Legacy)|BurnSim 3 documentation]] instead. Visit [https://burnsim.com burnsim.com] for downloads, news, and release history.
