interaction with multiple layers

I am trying to get the stress strain curve of graphene. In the data file, i set the z limits as -1000 and 1000 but yet I am able to visualize interaction with another layer when I see on vmd. There is no point at which it breaks because of this reason. Can someone please look into my input file and tell me if there is some sort of mistake that I am overlooking?

I am running the simulation with 800 atoms.

Thanks

Box bounds is one thing and inter-layer distance is another, right?

In addition, what VMD draws does not always truly represent real interatomic interactions.

Yes they are. I meant that by setting the distance between two layers as really high (z values), I tried to ensure that there is no interaction between the two layers (in periodic boundary conditions) yet I can observe another layer coming into the picture and interacting with it halfway through the simulation. I also don’t see any breaking, as is expected near 0.2 strain.

Thanks.

How was this done exactly and what was done for verification? There is not
enough information to determine and help. The questions you ask are about
your model and its analysis/visualization, which has nothing much to do
with LAMMPS.
