I notice that the velocity.html has been updated, but there is yet some little errors in this page:
“The ramp style is similar to that used by the compute temp/ramp ramp command.”
should be
“The ramp style is similar to that used by the compute temp/ramp command.”
The temp option is used by create and scale to specify a user-defined way of computing temperature. If this option is not used, create and scale compute temperature with the style “full” for the group of atoms whose velocity is being altered. See the temperature command for details. If the computed temperature should have degrees-of-freedom removed due to fix constraints (e.g. SHAKE or rigid-body constraints), then the appropriate fix command must be specified before the velocity command is issued.
The temperature command maybe should be replaced by compute temp command.
May the document be perfect!
