Hello users,
I am finding difficulties in locating cylindrical indenter in z axis.please check my script and resolve my problem. i am writing my script below.

what do you mean by “locating cylindrical indenter”?

please note, that this is a mailing list where people discuss using the LAMMPS MD software. it is NOT a “go and do my thinking and my work for me” service.
