该技术论文介绍了一个软件包，该软件包旨在在Horizon协作的背景下为大型宇宙学模拟产生初始条件。 “最初的条件，以大量累积的CPU和内存使用量。并用于生成大型流体动力和暗物质模拟的初始条件。
This technical paper describes a software package that was designed to produce initial conditions for large cosmological simulations in the context of the Horizon collaboration. These tools generalize E. Bertschinger’s Grafic1 software to distributed parallel architectures and offer a flexible alternative to the Grafic2 software for “zoom” initial conditions, at the price of large cumulated CPU and memory usage. The codes have been validated up to resolutions of 40963 and were used to generate the initial conditions of large hydrodynamical and dark matter simulations. They also provide means to generate constrained realizations for the purpose of generating initial conditions compatible with, for example, the local group or the SDSS catalog.
