+dump cfg/uef command :h3
+
+[Syntax:]
+
+dump ID group-ID cfg/uef N file mass type xs ys zs args :pre
+
+ID = user-assigned name for the dump :ulb,l
+group-ID = ID of the group of atoms to be dumped :l
+N = dump every this many timesteps :l
+file = name of file to write dump info to :l
+args = same as args for "dump custom"_dump.html :pre
+
+:ule
+
+[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"_fix_nh_uef.html or
+"fix npt/uef"_fix_nh_uef.html 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 USER-UEF package. It is only enabled if
+LAMMPS was built with that package. See the
+"Making LAMMPS"_Section_start.html#start_3 section for more info.
+
+This command can only be used when "fix nvt/uef"_fix_nh_uef.html
+or "fix npt/uef"_fix_nh_uef.html is active.
+
