metal sliding, result incorrect by showing in xmovie

I am new to use Lammps to do molecular dynamics simulations.
I am start doing with sample simulation of two sample Cu metal slide each other. The in file is attached above.
I use the “Cu_u3.eam” file that lammps package came with.
I xmovie the simulation, the result doesn’t seem correct.
I wonder if someone can take a look of my file and help me to debug my in file.

Thank you very much

unless you have proof that your have found a bug in the lammps code,
nobody will be running your input and checking it out.

don't you have some advisor or equivalent that is overseeing your work?
teaching you how to do proper MD, is the job of that person, so that would
be the person to talk to. if you want to have a tutor beyond that, you
will have to provide a compensation for the time spent on tutoring you.
