nve/awpmd = style name of this fix command
fix 1 all nve/awpmd
Perform constant NVE integration to update position and velocity for nuclei and electrons in the group for the Antisymmetrized Wave Packet Molecular Dynamics model. V is volume; E is energy. This creates a system trajectory consistent with the microcanonical ensemble.
The operation of this fix is exactly like that described by the fix nve command, except that the width and width-velocity of the electron wave functions are also updated.
Restart, fix_modify, output, run start/stop, minimize info
No information about this fix is written to binary restart files. None of the fix_modify options are relevant to this fix. No global or per-atom quantities are stored by this fix for access by various output commands. No parameter of this fix can be used with the start/stop keywords of the run command. This fix is not invoked during energy minimization.
This fix is part of the AWPMD package. It is only enabled if LAMMPS was built with that package. See the Build package page for more info.
