Our codes:
These codes are available for free download, and for use in building your own code. (Note some subroutines are copyright (c) Matthew Choptuik, and are not necessarily available for more than pedagogical uses.) However, we do not maintain or "support" them. We are happy to collaborate with anyone wishing our assistance in developing more sophisticated codes.
