High-precision digital lunar particle modeling based on Chang'E 5 samples

There is a high-precision digital lunar soil model library, systematically collecting five key types of data:(1)optical micrographs of lunar soil particles; (2)high-resolution X-CT source files; (3)STL mesh models of the particles and respective components; (4)multi-sphere discrete element models based on EDEM software; (5)finite element models with component calibration.本数据集为高精度数字月壤模型库，系统性收录了五类核心数据：(1)月壤颗粒光学显微照片；(2)高分辨率X射线计算机断层扫描（X-CT）源文件；(3)颗粒及其组成部分的STL网格模型；(4)基于EDEM软件的多球离散元模型；(5)带有组分校准的有限元模型。
