+deterministic integrator (e.g. "fix nve"_fix_nve.html) that updates
+the particle positions and velocities.
+

+Treat the surface of the geometric region defined by the {region-ID}
+as a bounding frictional wall which interacts with nearby finite-size
+granular particles when they are close enough to touch the wall.  See

+
+:line
+
+The distance between a particle and the region boundary is the
+distance to the nearest point on the region surface.  The force the
+wall exerts on the particle is along the direction between that point
+and the particle center, which is the direction normal to the surface
+at that point.  Note that if the region surface is comprised of
+multiple "faces", then each face can exert a force on the particle if
+it is close enough.  E.g. for "region_style block"_region.html, a
+particle in the interior, near a corner of the block, could feel wall
+forces from 1, 2, or 3 faces of the block.
+
+Regions are defined using the "region"_region.html command.  Note that
+the region volume can be interior or exterior to the bounding surface,
+which will determine in which direction the surface interacts with
+particles, i.e. the direction of the surface normal. The exception to
+this is if one or more {open} options are specified for the region
+command, in which case particles interact with both the interior and
+exterior surfaces of regions.
+
+Regions can either be primitive shapes (block, sphere, cylinder, etc)
+or combinations of primitive shapes specified via the {union} or
+{intersect} region styles.  These latter styles can be used to
+construct particle containers with complex shapes.  Regions can also
+move dynamically via the "region"_region.html command keywords (move)
+and {rotate}, or change their shape by use of variables as inputs to
+the "region"_region.html command.  If such a region is used with this
+fix, then the region surface will move in time in the corresponding
+manner.
+
+NOTE: As discussed on the "region"_region.html command doc page,
+regions in LAMMPS do not get wrapped across periodic boundaries.  It
+is up to you to ensure that the region location with respect to
+periodic or non-periodic boundaries is specified appropriately via the
+"region"_region.html and "boundary"_boundary.html commands when using
+a region as a wall that bounds particle motion.
+
+NOTE: For primitive regions with sharp corners and/or edges (e.g. a
+block or cylinder), wall/particle forces are computed accurately for
+both interior and exterior regions.  For {union} and {intersect}
+regions, additional sharp corners and edges may be present due to the
+intersection of the surfaces of 2 or more primitive volumes.  These
+corners and edges can be of two types: concave or convex.  Concave
+points/edges are like the corners of a cube as seen by particles in
+the interior of a cube.  Wall/particle forces around these features
+are computed correctly.  Convex points/edges are like the corners of a
+cube as seen by particles exterior to the cube, i.e. the points jut
+into the volume where particles are present.  LAMMPS does NOT compute
+the location of these convex points directly, and hence wall/particle
+forces in the cutoff volume around these points suffer from
+inaccuracies.  The basic problem is that the outward normal of the
+surface is not continuous at these points.  This can cause particles
+to feel no force (they don't "see" the wall) when in one location,
+then move a distance epsilon, and suddenly feel a large force because
+they now "see" the wall.  In a worst-case scenario, this can blow
+particles out of the simulation box.  Thus, as a general rule you
+should not use the fix wall/gran/region command with {union} or
+{interesect} regions that have convex points or edges resulting from
+the union/intersection (convex points/edges in the union/intersection
+due to a single sub-region are still OK).
+
+NOTE: Similarly, you should not define {union} or {intersert} regions
+for use with this command that share an overlapping common face that
+is part of the overall outer boundary (interior boundary is OK), even
+if the face is smooth.  E.g. two regions of style block in a {union}
+region, where the two blocks overlap on one or more of their faces.
+This is because LAMMPS discards points that are part of multiple
+sub-regions when calculating wall/particle interactions, to avoid
+double-counting the interaction.  Having two coincident faces could
+cause the face to become invisible to the particles.  The solution is
+to make the two faces differ by epsilon in their position.
+
+The nature of the wall/particle interactions are determined by the
+{fstyle} setting.  It can be any of the styles defined by the
+"pair_style granular"_pair_gran.html commands.  Currently this is
+{hooke}, {hooke/history}, or {hertz/history}.  The equation for the
+force between the wall and particles touching it is the same as the
+corresponding equation on the "pair_style granular"_pair_gran.html doc
+page, but the effective radius is calculated using the radius of the
+particle and the radius of curvature of the wall at the contact point.
+
+Specifically, delta = radius - r = overlap of particle with wall,
+m_eff = mass of particle, and RiRj/Ri+Rj is the effective radius, with
+Rj replaced by the radius of curvature of the wall at the contact
+point.  The radius of curvature can be negative for a concave wall
+section, e.g. the interior of cylinder.  For a flat wall, delta =
+radius - r = overlap of particle with wall, m_eff = mass of particle,
+and the effective radius of contact is just the radius of the
+particle.
+
+The parameters {Kn}, {Kt}, {gamma_n}, {gamma_t}, {xmu} and {dampflag}
+have the same meaning and units as those specified with the
+"pair_style granular"_pair_gran.html commands.  This means a NULL can
+be used for either {Kt} or {gamma_t} as described on that page.  If a
+NULL is used for {Kt}, then a default value is used where {Kt} = 2/7
+{Kn}.  If a NULL is used for {gamma_t}, then a default value is used
+where {gamma_t} = 1/2 {gamma_n}.
+
+Note that you can choose a different force styles and/or different
+values for the 6 wall/particle coefficients than for particle/particle
+interactions.  E.g. if you wish to model the wall as a different
+material.
+
+[Restart, fix_modify, output, run start/stop, minimize info:]
+
+Similiar to "fix wall/gran"_fix_wall_gran.html command, this fix
+writes the shear friction state of atoms interacting with the wall to
+"binary restart files"_restart.html, so that a simulation can continue
+correctly if granular potentials with shear "history" effects are
+being used.  This fix also includes info about a moving region in the
+restart file.  See the "read_restart"_read_restart.html command for
+info on how to re-specify a fix in an input script that reads a
+restart file, so that the operation of the fix continues in an
+uninterrupted fashion.
+
+Note that info about region definitions is NOT included in restart
+files.  So you must re-define your region and if it is a moving
+region, define its motion attributes in a way that is consistent with
+the simulation that wrote the restart file.  In particular, if you
+want to change its motion attributes (e.g. its velocity), then you
+should insure the postition/orientation of the region at the initial
+restart timestep is the same as it was on the timestep the restart
+file was written.  If this is not possible, then you may need to
+ignore info in the restart file by defining a new fix wall/gran/region
+command in your restart script (e.g. with a different fix ID).
+
+None of the "fix_modify"_fix_modify.html options are relevant to this
+fix.  No global or per-atom quantities are stored by this fix for
+access by various "output commands"_Section_howto.html#howto_15.  No
+parameter of this fix can be used with the {start/stop} keywords of
+the "run"_run.html command.  This fix is not invoked during "energy
