About fix append/atoms

Hi all users,

I want to ask what the initial pressure of the appended atoms of fix append/atom command is?

And if I want to change this value, can I do that?

Best Wishes

Hi all users,

I want to ask what the initial pressure of the appended atoms of fix
append/atom command is?

there is no such thing as "a pressure" for that.

append/atoms adds atoms on a lattice the same way create_atoms does.
its impact on the pressure of the system is governed by position of
the atoms relative to each other and the potential parameters, just as
with create_atoms. and there is the kinetic component as well.

And if I want to change this value, can I do that?

you can change any of the parameters that determine how the appended
atoms impact the pressure of your system, of course.
