Serpent Wiki (original) (raw)
NOTE: Serpent is not open source software. The source code is proprietary and subject to export control limitations. The terms and conditions for using Serpent are listed in the software license agreement. For more information on distribution, see Serpent website.
NOTE: The Serpent Wiki is being replaced by new on-line documentation at: https://serpent.vtt.fi/docs/. The two documentations are currently used to complement each other, but the content of the Wiki is no longer updated.
Welcome to Serpent Wiki. This platform, set up in November 2015, serves as the on-line user Manual for Serpent 2, as well as a repository for input files, validation reports and other resources for Serpent users. A more general description of the code is found at the project website. This Wiki covers the features and capabilities of the most recent version of Serpent 2. The content is still very far from complete, and additional information can be found from the Serpent 1 Manual and the discussion forum
For general reference to Serpent, use:
