This code works fine in small-scale simulations (4 nm), but when the scale is expanded to 30 nm, the output becomes nan when pressed down. I would like to ask what causes this.

Please read the guidelines before posting, this post probably violates every single rule (no LAMMPS version! using pictures instead of text of the code! having your entire question and context in the title!), and I am quite sure that nobody will help you. You can easily edit your post.
