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. For detailed information about the parameters used in the simulations please refer to Table1 in the paper.

3).VTK outputs of the simulation cases above for visualization. The VTK files are names as -spheres-{iteration number}.vtk, which includes the particles information: position, velocity(linVelocity), angular velocity(angVelocity), mass, material id (mat_rand), id, number of contacts(numOfContacts). Note: Time(sec)= iteration number/(5*1e-6* nCG)
