lammps for sandbox simulation

Dear all

I interest to study geodynamics using LAMMPS simulation. Following link is
analogy of physics modeling (sandbox) of geodynamics of the fault on the

I want to use LAMMPS at coarse grain scale to simulate the analog modeling
as shown in above video. I am a geophysics, strong in programming but poor
knowledge for atomic or molecular dynamics.

Would you inform me, is there any input and data file which close to the
video and I can start learn and modify from the input file.

Thank you for your help and information.

Best regards,

There is a granular package for lammps, probably that would be a good starting point.
