Welcome to the astro-tigress wiki!
Currently, the data is located at this webpage. You can browse and download individual files. However, you will need to preserve the file structure (folders and sub-folders) for the scripts provided here to work properly (you can also modify the file names in the scripts if you don't want to use the same file structure).
The scripts for reading the outputs are written in Python 3. I manage my python installation, versions, and packages with Anaconda.
yt can be used to read the MHD simulation outputs from Athena++. It allows part of the simulation domain to be accessed without loading the whole simulation output in the memory, which improves the time and memory efficiency of reading the output data. Since the molecular gas is largely located at the galactic mid-plane, we only need to access the MHD simulation output near the mid-plane region.
You can install yt here: https://yt-project.org/#getyt
I recommend installing yt using Anaconda. This will guarantee that all the packages (such as yt, numpy, scipy etc) work together.
The Astropy package is needed for converting the sythetic CO emission line maps made by RADMC-3D to FITS files. Astropy can also be installed using Anaconda.
Start with playing the jupyter notebooks analysis/, which contains examples for reading and analysing the data.
read_data_1-MHD.ipynb shows you how to work with the original TIGRESS MHD output data (Kim & Ostriker (2017)), and read_data_2-chem-CO_lines.ipynb gives examples working with the chemistry and CO line post-processing data (Gong et al 2018, Gong et al. 2020).
There are three different folders:
analysis: Jupyter notebooks for data reading and analysis
module: Python modules that are used in the Jupyter notebooks
miscellaneous: Other stuff. copy_data.ipynb for example, is used by the developer to move simulation data into the data release storage.
