- pynbody.analysis.ramses_util.convert_to_tipsy_simple(output, halo=0, filt=None)[source]#
Convert RAMSES output to tipsy format readable by e.g. pkdgrav. This is a quick and dirty conversion, meant to be used for quick visualization or other simple post processing. Importantly, none of the cosmologically-relevant information is carried forward. For a more complete conversion for e.g. running through pkdgrav or Amiga Halo Finder, see
convert_to_tipsy_fullbox()
.The snapshot is put into units where G=1, time unit = 1 Gyr and mass unit = 2.222286e5 Msol.
Input:
