dump cfg/uef command
dump ID group-ID cfg/uef N file mass type xs ys zs args
ID = user-assigned name for the dump
group-ID = ID of the group of atoms to be dumped
N = dump every this many timesteps
file = name of file to write dump info to
args = same as args for dump custom
dump 1 all cfg/uef 10 dump.\*.cfg mass type xs ys zs dump 2 all cfg/uef 100 dump.\*.cfg mass type xs ys zs id c_stress
This command is used to dump atomic coordinates in the reference frame of the applied flow field when fix nvt/uef or fix npt/uef or is used. Only the atomic coordinates and frame-invariant scalar quantities will be in the flow frame. If velocities are selected as output, for example, they will not be in the same reference frame as the atomic positions.
This fix is part of the USER-UEF package. It is only enabled if LAMMPS was built with that package. See the Build package doc page for more info.
