+Description
+"""""""""""
+
+This fix implements flow boundary conditions (FBC) introduced in :ref:`(Pavlov) <fbc-Pavlov1>` and :ref:`(Pavlov) <fbc-Pavlov2>`.
+The goal is to generate a stationary flow with a shifted Maxwell velocity distribution:
+
+.. math::
+
+   f_z(v_z) \propto \exp{\left(-\frac{m (v_z-v_{\text{flow}})^2}{2 k T}\right)}
+
+This is achieved by reassigning the velocity of each particle that passes a wall.
+Such reassigning represents an emission of a new particle into the system with
+simultaneous removal of a particle with the same position.
+The parallel velocity components parallel to the wall are re-assigned according
+to the Maxwell velocity distribution. The perpendicular component is assigned
+according to the following velocity distribution:
+
+.. math::
+
+   f_{\text{z generated}}(v_z) \propto v_z f_z(v_z)
+
+It can be shown that in an ideal-gas scenario this makes the velocity
+distribution of particles between walls exactly as desired.
+
+Since in most cases simulated systems are not ideal gas,
+the need for multiple walls might arise, as a single wall may not be
+sufficient for maintaining a stationary flow without congestions
+manifesting as areas with increased density located upstream from static obstacles.
+
+For the same reason, the actual temperature and velocity of the generated
+flow may differ from ones requested. The degree of such discrepancy is determined
+by how different from the ideal gas the simulated system is. Therefore, a calibration procedure is required for each system as described in :ref:`(Pavlov) <fbc-Pavlov2>`.
+
+The interactions between particles on different sides of a wall are not disabled or neglected and the
+particle positions aren't affected by the velocity reassignment.
+This removes the need to modify the force field to work correctly in cases when a particle is close
+to a wall (for example, if particle positions were uniformly redistributed across the surface of the wall,
+two particles could end up too close to each other, potentially causing the simulation to explode).
+However due to this compromise, some collective phenomena such as areas with increased/decreased density
+or collective movements are not fully removed when particles cross a wall.
+This unwanted consequence can also be potentially mitigated by using more than one wall.
+
+
+----------
+
+Note that when high flow velocity is reached, a lost atoms error may
+occur (see :doc:`error messages <Errors_messages>`).
+If this message appears when using this fix, you can, for example, reduce the frequency of the
+neighbor list rebuild via :doc:`neigh_modify <neigh_modify>` command.
