tardis.io.model.readers.arepo module¶

class tardis.io.model.readers.arepo.ArepoSnapshot(filename, species, speciesfile, alpha=0.0, beta=0.0, gamma=0.0)[source]¶

Bases: object

Loads relevant data for conversion from Arepo snapshot to a csvy-model. Requires arepo-snap-util to be installed. The snapshot is mapped onto a Cartesian grid before further processing is done.

Parameters

filenamestr: Path to file to be converted.
specieslist of str: Names of the species to be exported. Have to be the same as in the species-file of the Arepo simulation
speciesfilestr: File specifying the species used in the Arepo simulation.
alphafloat: Euler angle alpha for rotation of the desired line- of-sight to the x-axis. Only usable with snapshots. Default: 0.0
betafloat: Euler angle beta for rotation of the desired line- of-sight to the x-axis. Only usable with snapshots. Default: 0.0
gammafloat: Euler angle gamma for rotation of the desired line- of-sight to the x-axis. Only usable with snapshots. Default: 0.0

get_grids()[source]¶: Returns all relevant data to create Profile objects

class tardis.io.model.readers.arepo.ConeProfile(pos, vel, rho, mass, xnuc, time)[source]¶

Bases: Profile

Class for profiles extracted inside a cone around the x-axis. Extends Profile.

Parameters

poslist of float: Meshgrid of positions in center of mass frames in Cartesian coordinates
vellist of float: Meshgrid of velocities/ velocity vectors
rholist of float: Meshgrid of density
masslist of float: Meshgrid of masses.
xnucdict: Dictonary containing all the nuclear fraction meshgrids of the relevant species.
timefloat: Time of the data

create_profile(opening_angle=20.0, inner_radius=None, outer_radius=None, show_plot=True, save_plot=None, plot_dpi=600)[source]¶

Creates a profile along the x-axis without any averaging

Parameters

opening_anglefloat: Opening angle (in degrees) of the cone from which the data is extracted. Refers to the total opening angle, not the angle with respect to the x axis. Default: 20.0
inner_radiusfloat: Inner radius where the profiles will be cut off. Default: None
outer_radiusfloat: Outer radius where the profiles will be cut off. Default: None

Returns

profileConeProfile object

class tardis.io.model.readers.arepo.FullProfile(pos, vel, rho, mass, xnuc, time)[source]¶

Bases: Profile

Class for profiles extracted from the full snapshot, i.e. angle averaged profiles. Extends Profile.

Parameters

poslist of float: Meshgrid of positions in center of mass frames in Cartesian coordinates
vellist of float: Meshgrid of velocities/ velocity vectors
rholist of float: Meshgrid of density
masslist of float: Meshgrid of masses.
xnucdict: Dictonary containing all the nuclear fraction meshgrids of the relevant species.
timefloat: Time of the data

create_profile(inner_radius=None, outer_radius=None, show_plot=True, save_plot=None, plot_dpi=600)[source]¶

Creates a profile from the full snapshot. Positive and negative direction are identical.

Parameters

inner_radiusfloat: Inner radius where the profiles will be cut off. Default: None
outer_radiusfloat: Outer radius where the profiles will be cut off. Default: None

Returns

profileFullProfile object

class tardis.io.model.readers.arepo.Profile(pos, vel, rho, mass, xnuc, time)[source]¶

Bases: object

Parent class of all Profiles. Contains general function, e.g. for plotting and export.

Parameters

poslist of float: Meshgrid of positions in center of mass frames in Cartesian coordinates
vellist of float: Meshgrid of velocities/ velocity vectors
rholist of float: Meshgrid of density
masslist of float: Meshgrid of masses.
xnucdict: Dictonary containing all the nuclear fraction meshgrids of the relevant species.
timefloat: Time of the data

export(nshells, filename, direction='pos', overwrite=False)[source]¶

Function to export a profile as csvy file. Either the positive or negative direction can be exported. By default does not overwrite existing files, saves to <filename>_<number>.csvy file instead.

Parameters

nshellsint: Number of shells to be exported.
filenamestr: Name of the exported file
directionstr: Specifies if either the positive or negative direction is to be exported. Available options: [‘pos’, ‘neg’]. Default: pos
overwrite: bool: If true, will overwrite if a file of the same name exists. By default False.

Returns

filenamestr: Name of the actual saved file

get_profiles()[source]¶: Returns all profiles for manual post_processing etc.

plot_profile(save=None, dpi=600, **kwargs)[source]¶

Plots profile, both in the positive and negative direction.

Parameters

savestr: Path under which the figure is to be saved. Default: None
dpiint: Dpi of the saved figure
**kwargskeywords passable to matplotlib.pyplot.plot()

Returns

figmatplotlib figure object

rebin(nshells)[source]¶

Rebins the data to nshells. Uses the scipy.stats.binned_statistic to bin the data. The standard deviation of each bin can be obtained by passing the statistics=”std” keyword.

Parameters

nshellsint: Number of bins of new data.

Returns

selfProfile object
