Each time a particle in the specified group passes through one of the
transparent walls, its velocity is re-assigned. Particles not in the
group do not interact with the wall.
group do not interact with the wall. This can be used, for example, to
add obstacles composed of atoms, or to simulate a solution of complex
molecules in a one-atom liquid (note that the fix has been tested for
one-atom systems only).
Conceptually, the velocity re-assignment represents creation of a new
particle within the system with simultaneous removal of the particle

Flow boundary conditions should not be used with rigid bodies such as
those defined by a "fix rigid" command.
This fix can only be used with periodic boundary conditions along the
flow axis. The size of the box in this direction must not change. Also,
the fix is designed to work only in an orthogonal simulation box.
