1. ABOUT THE DATASET -------------------- Title: A dataset for the paper "An exploration of dust grain growth within WCd systems using an advected scalar dust model" Creator(s): J W Eatson [1,2], J M Pittard [1], S Van Loo [1,3] Organisation(s): 1. University of Leeds 2. University of Sheffield 3. Ghent University Rights-holder(s): J W Eatson [1,2], J M Pittard [1], S Van Loo [1,3] Publication Year: 2022 Description: This dataset contains the simulation data for the paper "An exploration of dust grain growth within WCd systems using an advected scalar dust model", which is a parameter space search of colliding wind binary (CWB) systems. The main parameters varied influence the momentum ratio, velocity ratio and cooling parameter. The simulations were generated using a modified version of the Athena++ hydrodynamical code (the modified version is included in the repository), which was rewritten to include a rudimentary dust model, orbital mechanics, wind outflows and radiative cooling. Plotting code is also included to read these files and repoduce the plots from our papers. Data is stored in the form of .HDF5 files, which are an open standard. The entire output of the simulation was considered too large to store (>100 TB), and as such measures were taken to ensure that this data can be replicated.

PROJECT AND FUNDING INFORMATION ---------------------------------- Title: Numerical Simulations of Dusty Colliding Wind Binaries Dates: October 2017 - April 2022 Funding organisation: Self-funded, this data was not created in the course of a funded project Grant no.: N/A 4. CONTENTS ----------- File listing - athena-cwb-dust.zip: a copy of the modified Athena++ code, the main modifications are in the files cwb.cpp in src/, this is documented in the form of comments, the original codebase wiki is also useful for additional documentation, https://github.com/PrincetonUniversity/athena/wiki - cwb-2d-slice-data.zip: 2D slices of data used in graphics figures throughout the paper, the full 3D volume is not included as they are extremely large - cwb-hst-plot-data.zip: volume summated data in the form of comma-separated values, these can be used to reproduce the all of the line plots from the paper, files are self documenting. - plotting-scripts.zip: A series of python scripts used to produce plots from the Athena++ data, these are documented through comments and docstrings. - simulation-input-files.zip: Input files for athena++ for each simulation conducted, see Tables 5 & 6 for the simulation parameters. Keep in mind these are very large simulations, typically run with 128 cores and ~4GB of RAM per core! Processing time for each simulation was approximately a week. 5. METHODS ---------- - Simulations were conducted using a modified version of the Athena++ hydrodynamical code. - Modifications extensive, but incorporating a multitude of methods best described in my thesis: https://etheses.whiterose.ac.uk/32292/, see Chapter 3, in particular Sections 3.4, 3.6 and 3.7. - Grid data is stored in the form of HDF5 files, see the Athena documentation at https://github.com/PrincetonUniversity/athena/wiki/HDF5-Format - Volume averaged time variant data "history files" are stored as comma separate values, see the Athena++ documentation at https://github.com/PrincetonUniversity/athena/wiki/Outputs
