I am working on modifying an existing nano-indentation molecular dynamics script in LAMMPS to perform nano-scratching simulations. In this setup, the indenter initially moves vertically downward to make contact with the substrate surface and then slides laterally along the X or Y direction, producing a scratch track. This simulation approach is used to investigate tribological and wear behavior, including friction forces, surface damage, pile-up formation, and subsurface deformation at the atomic scale. I understand that developing this setup requires proper scripting and computational resources. Any guidance, example scripts, or relevant references related to nano-scratch simulations in LAMMPS would be highly appreciated.

@REHAD_SINDID_PATWARY Please have a look at my response to this post: Using LAMMPS for HEAs simulations - #2 by akohlmey
Pretty much everything I write there applies to your post as well, with the obvious adjustment for the difference in research topic.
Thanks to knowing me. I read that before. But any suggestions or resources would be greatful for me. I post here to get help regarding on this case. I have a time issues for that reason I need to find out it as soon as possible. For that reason I’m looking for available sources and resources.
Sorry, but people responding here have “time issues”, too.
If you need specific help and expedited tutoring from somebody that has experience with your specific research topic, you (or your adviser/supervisor) have to reach out directly to research groups that have a track record in that area and negotiate terms for a collaboration. You are extremely unlikely to find that in a public forum: first of all, the chances that somebody that is responding to posts is also an expert in your area of research are extremely small, but also consider what would you do, if you have spent some significant time developing an expertise in performing a certain type of simulation and you are asked by an person you don’t know to share it without any assurance of getting in some shape or form compensated for investing all that time and effort to provide all that information and expertise? What you are asking about is ultimately the task of an adviser or tutor. As I mentioned in the other topic, your best chance to find on-topic suggestions is to search the published literature. If you get lucky, the authors of the publication(s) have made their input scripts available as supplemental information (it is not commonly done, though, in my experience).
I understand your predicament, but you have to apply common sense to what you are asking for, too.
