Starscream is a code that I have developed for creating galaxy progenitors for N-body codes. The code implements a Springel-Hernquist model with a dark matter halo and a stellar disk, in a nutshell, and can write these initial conditions to a GADGET2 input file or others. More information is available in the manual.

Version 1.x The code is free to anyone who would like to use it, but comes with no warranty, neither expressed nor implied.

There are some videos of galaxy collisions created with Starscream and GADGET2 on Youtube.

Release Status: v1.1– 20110625, available here. Made a fix to support FFTW-3.2.2.

Repo Update: Replaced Autoconf with CMake!

License Info: Starscream 1.x is released under the GPL.

Version 2.x Development on Starscream 2.0 has started and is, as usual, infinitely delayed. All I really know at the moment is that Starscream 2.0 will be written in 100% Java and it will be a plugin of my other project, the NEAMS Integrated Computational Environment (NiCE). I'm doing this because for a lot of reasons and I will try to find time to document those on the wiki. Right now I am busy re-designing and re-implementing a lot of the underlying math pieces of Starscream 1.x to work in Java. Version 2.0 will be released under the New/Modified BSD License.
