Hi All,
I want to make nano scratch in lammps program and conical tool tip in nano indentation. I read the documents on lammps, but somehow I could not. If you have an existing sample can you send me, I would be glad if you help me?
Best Regards
To create a conical tip (which presumably makes the scratch), one option
is to build it outside of LAMMPS and then input it as a data file. If LAMMPS
had a region cone command (see the other region options) you could do
this simply in LAMMPS, but no one has written one.
The other option is to use the create_atoms var option. If you can devise a 3d formula
that will give you 0/1 when an atom position is outside/inside the cone, then assign
that formula to a variable and that option will create atoms inside the cone.

how about this one?

Ha! I guess my memory does not go back 10+ years.

Please post to the mail list, not to me personally.
I don’t see a region cone command in your input script.
