gyrfalcON: N-body code

gyrfalcON (GalaxY simulatoR using falcON) is a full-fledged N-body code using Dehnen's force algorithm of complexity O(N) (falcON); this algorithm is approximately 10 times faster than an optimally coded tree code. The code features individual adaptive time steps and individual (but fixed) softening lengths. gyrfalcON is included in and requires <a href=http://ascl.net/1010.051>NEMO</a> (ascl:1010.051) to run.
