Dataset for "Reducing segregation in vibrated binary-sized granular mixtures by excessive small particle introduction" published in Granular Matter

This repository contains the simulation and analysis code, as well as the raw data used to generate the figures presented in the paper "Reducing segregation in vibrated binary-sized granular mixtures by excessive small particle introduction," published in Granular Matter. Simulation and Analysis Codes: The core simulation and analysis scripts are located primarily within the origin folder: origin/: This directory serves as a template and includes the following base files: base_input.txt: Defines the input parameters for the simulation. This file is modified by various_para.sh for different parameter sets. base_make_initial.c: A C program to construct the initial particle configurations. base_lammps.lmp: The main LAMMPS simulation script. base_analysis.c: A C program to analyze the radial distribution function (RDF). base_begin_pc.sh: A shell script that executes the main simulation and analysis workflow (base_make_initial.c, base_lammps.lmp, base_analysis.c). Please modify this script (base_begin_pc.sh) to match your specific computational environment. Other important scripts include: various_para.sh: This shell script automates the process of running simulations for various parameters. It creates copies of the origin folder, modifies the parameters in base_input.txt within each new folder, assigns appropriate folder names, and then executes base_begin_pc.sh in each folder. base_analysis_sk.py: A Python script designed to calculate the structure factor. sk.sh: This shell script distributes base_analysis_sk.py to each parameter-specific folder (created by various_para.sh) and executes the Python script to perform the structure factor calculation. Raw Data for Figures: The raw data used to generate the figures are organized into separate folders (please note that Figure 1 is a schematic representation and does not have a corresponding data folder): data_fig2-5/: Raw data for Figures 2-5. data_fig6-8/: Raw data for Figures 6-8. data_fig9-11/: Raw data for Figures 9-11. data_fig12-14/: Raw data for Figures 12-14. data_fig15-17/: Raw data for Figures 15-17. data_fig18-20/: Raw data for Figures 18-20. Within each of these data_fig* folders, the file data_main_large.dump contains the trajectory data specifically for the large particles.
