setvelocity

Set velocities for specified atoms using Maxwellian distribution based on given temperature.

setvelocity [<mask>] [tempi <temperature>] [ig <random seed>]

[<mask>] Mask of atoms to assign velocities to.
[tempi <temperature>] Assign velocities at specified temperature (default 300.0 K).
[ig <random seed>] Random seed to use to generate velocity distribution.

Set velocities in frame for atoms in <mask> using Maxwellian distribution based on given temperature.
