Hi,
I want to assign a time-dependent velocity on atoms, making the atoms vibrating with time. Part of the commands are as follow:
…
variable vz equal 100sin(0.00628step)
thermo_style custom step temp press etotal
velocity rightedge set NULL NULL v_vz units box
…
But it turned out atoms in group “rightedge” were not assigned with expected velocities. Could anybody help me out?
Thanks a lot for help!
