| dc.description | This repository contains the datasets from the original smoothed particle hydrodynamics (SPH) calculations for the associated paper, including most dump files. It also includes all of the scripts for generating the figures that appear in the paper. These are contained either in the Figure_Generation.zip file or in the Paper.zip file. The former mainly contains SPLASH scripts (see below) for generating images from the SPH dump files. The latter mainly contains the final (or intermediate) SPLASH figures, plus the data files and scripts for making the other figures (line plots). Line plots use supermongo scripts.
There are 5 main SPH calculations discussed in the paper, using 3 million SPH particles (3M) and with magnetic mass-to-flux ratios of 5, 10, 20, 100, and infinity (e.g. MF05). The outputs from each calculation are found in the zip files that begin with RMHD_MF*. For example, RMHD_MF05_3M.zip contains all the output (and executable) from the 3 million particle calculation with mass-to-flux ratio 5, except the dump files. The dump files are contained in a series of zip files such as: RMHD_MF05_3M_0200_0219.zip which contains 20 dump files, numbers 200 to 219. The dump files are included in groups to allow downloads in reasonably small (~20 GB) chunks, since the entire repository is ~3 TB.
Also included is the output from the 1 million particle, mass-to-flux ratio 5 calculation (which was used for resolution testing in the Appendix of the paper). Only the single dump file from the 10 million particle calculation which was used to generate figure 22 is included in the respository (within the Figure_Generation.zip file) because the dump files from the entire calculation occupied another 1 TB of disk space.
The SPH dump files for each calculation begin at TEST000 at time zero and then are numbered sequentially. The spacing in time is not regular (it generally decreases). The SPH dump files are Fortran binary files, written in big endian format and generated by the sphNG code. They can be read, visualised, and manipulated using the free, publicly available SPLASH visualisation code (which reads sphNG dump files), written by Daniel Price, that can be downloaded from:

Finally, the MovieAll.zip file contains the SPLASH scripts for generating the density movies associated with the paper that can be found at:
