abstract

Denmax finds gravitationally bound groups in cosmological
N-body simulations. Denmax takes input files in the tipsy binary format.
Denmax groups different types of particles depending on the type of
input binary file. The type may be dark matter particles, gas particles,
star particles, or gas and star particles.
Once groups with at least a certain minimum number of members
have been determined, denmax will remove particles which are not
bound to the group, using a procedure called unbinding. Denmax
produces output files in tipsy array, vector, and binary formats.
