Data set for "The sintering behavior of ellipsoidal particles"

This repository is the data described in the article "The sintering behavior of ellipsoidal particles".

The repository contains data for 25 simulations done using a kinetic Monte Carlo model of sintering.

Five different particle aspect ratios, AR, are considered. The simulations for each of these has its own folder. Within that folder are the five independent simulations run for each particle aspect ratio.

For each subdirectory, the data is stored as described below. 
The kinetic Monte Carlo sintering data, i.e. the voxel information as function of Monte Carlo Steps (MCS) is contained in the file "voxel_timesteps.mat", which is a Matlab data file containing two arrays. The first is the "atoms" array which is a 4D array with a number of simulation snapshots (i.e. where the state of the simulation is saved) and then voxel information in the 300x300x300 cubed lattice considered. Thus for example atoms(12,:,:,:) is the simulation snapshot 12 with voxel data for 300x300x300 sites. The voxel data is such that a simulation boundary site has a value of -1, a pore site a value of 0 and a grain site an integer value larger than 1. Different grains have different integer values. The other array in the matlab file is the "timestep" array which simply contains informations on how many MCS each simulation snapshot corresponds to.
All information presented in the article can be extracted from the kinetic Monte Carlo simulation snapshots. However, the information regarding relative density, mean grain size, strain and mean coordination number is, for ease of use, given in the "data_processed.txt" in each simulation sub-folder. The header in the file describe how the file is structured.

本仓库收录了论文《椭球形颗粒烧结行为》中描述的数据。该仓库包含利用烧结动力学蒙特卡洛模型进行的25次模拟数据。考虑了五种不同的粒子长宽比（AR），针对每种长宽比均有单独的文件夹存储对应的模拟数据。每个文件夹内包含针对每种粒子长宽比进行的五个独立模拟。对于每个子目录，数据存储方式如下。动力学蒙特卡洛烧结数据，即蒙特卡洛步数（MCS）函数的体素信息，存储于名为“voxel_timesteps.mat”的文件中，该文件为Matlab数据文件，包含两个数组。第一个数组为“atoms”数组，是一个四维数组，包含多个模拟快照（即保存模拟状态的时刻）以及考虑的300x300x300立方晶格中的体素信息。例如，atoms(12,:,:,:)代表第12个模拟快照的体素数据，对应于300x300x300个位点。体素数据中，模拟边界位点的值为-1，孔隙位点的值为0，晶粒位点的值为大于1的整数，不同晶粒具有不同的整数值。Matlab文件中的另一个数组是“timestep”数组，它简单地包含每个模拟快照对应的MCS数量。文章中展示的所有信息均可从动力学蒙特卡洛模拟快照中提取。然而，为了方便使用，关于相对密度、平均晶粒尺寸、应力和平均配位数的信息以“data_processed.txt”的形式提供在每个模拟子目录中。文件头部描述了文件的结构。
