Hello
velocity atom_pt set 0.0 -115 0.0 units box
run 40000
I am trying to give an INITIAL VELOCITY to a single atom in my simulation and see what happens.
My doubt is whether the the run command considers the velocity 115 in y-direction as initial velocity or
does it give 115 in each every time step of 40000 time steps.
Regards
Vikram

vikram,
this is the kind of question that any person with a sufficient
amount of common sense should not need to ask.
a) the documentation clearly says that the velocity command is a
one time only operation (unlike fixes)
b) you can _easily_ double check the effect by writing output to a
custom dump file where you output the velocities in addition to
the coordinates.
cheers,
