GenetIC—A New Initial Conditions Generator to Support Genetically Modified Zoom Simulations
Abstract We present genetIC , a new code for generating initial conditions for cosmological N -body simulations. The code allows precise, user-specified alterations to be made to arbitrary regions of the simulation (while maintaining consistency with the statistical ensemble). These “genetic modifications” allow, for example, the history, mass, or environment …
