osyris 2.3.1

A package to visualize AMR data from the RAMSES code

Osyris A python visualization utility for RAMSES astrophysical simulations data. Osyris aims to remain portable, lightweight and fast, to allow users to quickly explore and understand their simulation data, as well as produce publication grade figures.

Documentation

The documentation for osyris is hosted on Readthedocs.

Installation

pip install osyris

A short example

You can download the sample data here.

Plot a 2D histogram of the cell magnetic field versus the gas density.

import osyris
data = osyris.Dataset(8, scale="au", path="data").load()
osyris.histogram2d(data["hydro"]["density"], data["hydro"]["B_field"],
                   norm="log", loglog=True)

Create a 2D gas density slice 2000 au wide through the plane normal to z, with velocity vectors overlayed as arrows, once agains using layers:

ind = np.argmax(data["hydro"]["density"])
center = data["amr"]["xyz"][ind.values]
osyris.plane({"data": data["hydro"]["density"], "norm": "log"}, # layer 1
             {"data": data["hydro"]["velocity"], "mode": "vec"}, # layer 2
             dx=2000 * osyris.units("au"),
             origin=center,
             direction="z")
