class tardis.io.model.arepo.data.ArepoData(time: ~astropy.units.quantity.Quantity | float, position: ~numpy.ndarray, velocities: ~numpy.ndarray, densities: ~numpy.ndarray, mass: ~numpy.ndarray, isotope_dict: dict = <factory>)[source]¶

Bases: object

Data structure for Arepo snapshot data.

Parameters:

timeastropy.units.Quantity or float: Time of the snapshot. If a float is provided, it is assumed to be in seconds.
posnumpy.ndarray: Position array in Cartesian coordinates (3, N) in cm.
velnumpy.ndarray: Velocity array in Cartesian coordinates (3, N) in cm/s.
rhonumpy.ndarray: Density array in g/cm^3.
massnumpy.ndarray: Mass array in g.
nuc_dictdict: Dictionary of nuclear mass fractions keyed by species name.
