Question on Velocity Command

LAMMPS LAMMPS Mailing List Mirror

Hi all,

I was wondering if using the command:

velocity all create [temp] [seed] mom yes rot yes dist gaussian

would generate a distribution that was Maxwellian for the temperature specified in [temp], or if it would be necessary to equilibrate the system for some time to reach an equilibrium velocity distribution.

Thanks,

You always need to equilibrate, since not only do you here the right distribution, but also the individual atoms need to be consistent with it.
