problem with propagation of surface acostic waves in lammps

excusme, I am a bigginer with lammps and now is the first time that i post a
question in mailing list.
I want to create acoustic traveling waves in a nanotube, i use LJ potential
with periodic boundary condition, but i do not know what command in lammps
do this for me!
could you please help me?

Thanks

there is no problem with that. everybody is a beginner in something
somewhere. you should note that what kind of help and how much help
you can get depends on how well you can formulate your problem and
whether you respect the established conventions of this mailing list.
every mailing list community has some and they are often different
between different lists and communities. some explanations about this
are on the LAMMPS webpage.

there are no "just do this simulation" commands in LAMMPS. how to set
up a simulation for a specific purpose requires *you* to first figure
out how such a simulation needs to be set up and executed in general,
i.e. without any specific references to any specific simulation
software. once you have identified the necessary steps, you can look
through the available commands and identify the possible candidates.
then you make some small tests and when you have confidence in your
setting and choices, you will be able to do the study that you intend
to do.

could you please help me?

please note that this mailing list is not a classroom or beginner
tutorium. what you seem to be struggling with appears less the actual
features in LAMMPS, but rather the conceptual issue with how the
scenario that you want to study can be set up in general. this is
something that you should rather discuss with you
adviser/superviser/colleagues, as i have already hinted at in my
previous response.
