Data underlying the publication: A Coarse-Grained Discrete Element Model (CG-DEM) for dense wet granular system

Relevant files for reproducing base case simulations in the paper "A Coarse-Grained Discrete Element Model (CG-DEM) based on parameter scaling for dense wet granular system ", https://doi.org/10.1016/j.powtec.2024.120581.The files include: 1)The modified version of the ViscoelasticCapillarPM.cpp and ViscoelasticCapillarPM.hpp scripts in Yade-DEM source code, which includes the modification in the liquid viscous force and the calculation of the capillary force at the contact of two wet particles. For more information on how to install the source code of Yade please visit: https://yade-dem.org/doc/installation.html.2)Python scripts for running simulations for simulations in dry, wet without liquid migration, and wet with liquid migration. In these simulations, particles with coarse-graining factor of nCG=3 has been used. Note that the liquid migration engine should be activated for case of wet particle system with liquid migration.3).VTK outputs of the simulation cases above for visualization.

本数据集为论文《基于参数缩放的稠密湿颗粒系统粗粒度离散元模型（Coarse-Grained Discrete Element Model，CG-DEM）》中复现基础案例仿真所需的相关文件，关联DOI链接为https://doi.org/10.1016/j.powtec.2024.120581。文件包含以下内容：
1) Yade-DEM源代码中的ViscoelasticCapillarPM.cpp与ViscoelasticCapillarPM.hpp脚本的修改版本，该版本新增了液体粘性力的修改逻辑，以及两湿颗粒接触处毛细力的计算方法。如需了解Yade源代码的安装方式，请访问：https://yade-dem.org/doc/installation.html。
2) 用于运行仿真的Python脚本，覆盖干颗粒、无液体迁移湿颗粒以及带液体迁移湿颗粒三类仿真场景。本次仿真采用了粗粒度系数nCG=3的颗粒。请注意，对于带液体迁移的湿颗粒系统场景，需启用液体迁移引擎。
3) 上述三类仿真案例的VTK输出文件，用于可视化展示。
