dump cfg/uef command

Syntax

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
```

Examples

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

Description

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 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.

Restrictions

This fix is part of the UEF package. It is only enabled if LAMMPS was built with that package. See the Build package page for more info.

This command can only be used when fix nvt/uef or fix npt/uef is active.

Default

none
