I plan to use a virtual half-plane indenter to perform the nano-indentation operation as shown in the figure below. After reading the fix indent plane in the lammps manual, I found that the planar indenter is really an axis-aligned infinite-extent wall exerting the same force on atoms in the system ,The following is the command line I wrote. What I want to ask is how to modify it to achieve the effect of the intermediate half-plane indenter.
variable zzero equal 106
variable vel equal 0.1
variable name equal “v_zzero - v_velstepdt”
variable depth equal “v_velstepdt”
fix 4 all indent 10.0 plane z v_name hi units box
