LIGGGHTS is a molecular simulator. The name stands for Large-scale Atomic/Molecular Massively Parallel Simulator.
It can also be used to simulate the collision and shearing of sand for example and other granular materials. The results of the simulations can be exported into any custom file format or when the build contains VTK, it can be used as well. Later these files can be viewed in ParaView or opened in Python.
Building can be a little complicated: Building LIGGGHTS.
After installation any LIGGGHTS file can be run like this through MPI:
mpirun -np 4 lmp_auto < in.name_of_liggghts_file
Then the VTK files got as an output can be viewed in ParaView.
