* ID = user-assigned name for the dump
* group-ID = ID of the group of atoms to be dumped
* N = dump every this many timesteps

Examples

Description
"""""""""""

This command is used to dump atomic coordinates in the
reference frame of the applied flow field when
:doc:`fix nvt/uef <fix_nh_uef>` or
:doc:`fix npt/uef <fix_nh_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.

Restrictions
""""""""""""

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

This command can only be used when :doc:`fix nvt/uef <fix_nh_uef>`
or :doc:`fix npt/uef <fix_nh_uef>` is active.
