granular force fields. This is to emphasize the fact that the
Hertzian equation has changed to model polydispersity more accurately.
A side effect of the change is that the Kn, Kt, gamma_n, and gamma_t
coefficients in the pair_style command must be specified with
different values in order to reproduce calculations made with earlier
versions of LAMMPS, even for monodisperse systems. See the NOTE below

< p > The < em > gran< / em > styles use the following formulas for the frictional force
between two granular particles, as described in

< a class = "reference internal" href = "#zhang" > < span class = "std std-ref" > (Zhang)< / span > < / a > , when the distance r between two particles of radii
Ri and Rj is less than their contact distance d = Ri + Rj. There is
no force between the particles when r > d.< / p >
< p > The two Hookean styles use this formula:< / p >
< img alt = "_images/pair_gran_hooke.jpg" class = "align-center" src = "_images/pair_gran_hooke.jpg" / >
< p > The Hertzian style uses this formula:< / p >
< img alt = "_images/pair_gran_hertz.jpg" class = "align-center" src = "_images/pair_gran_hertz.jpg" / >
< p > In both equations the first parenthesized term is the normal force
between the two particles and the second parenthesized term is the
tangential force. The normal force has 2 terms, a contact force and a
damping force. The tangential force also has 2 terms: a shear force
and a damping force. The shear force is a “ history” effect that
accounts for the tangential displacement between the particles for the
duration of the time they are in contact. This term is included in
pair styles < em > hooke/history< / em > and < em > hertz/history< / em > , but is not included
in pair style < em > hooke< / em > . The tangential damping force term is included
in all three pair styles if < em > dampflag< / em > is set to 1; it is not included
if < em > dampflag< / em > is set to 0.< / p >

< / ul >
< p > The Kn, Kt, gamma_n, and gamma_t coefficients are specified as
parameters to the pair_style command. 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.< / p >
< p > The interpretation and units for these 4 coefficients are different in
the Hookean versus Hertzian equations.< / p >
< p > The Hookean model is one where the normal push-back force for two
overlapping particles is a linear function of the overlap distance.
Thus the specified Kn is in units of (force/distance). Note that this
push-back force is independent of absolute particle size (in the
monodisperse case) and of the relative sizes of the two particles (in
the polydisperse case). This model also applies to the other terms in
the force equation so that the specified gamma_n is in units of
(1/time), Kt is in units of (force/distance), and gamma_t is in units
of (1/time).< / p >
< p > The Hertzian model is one where the normal push-back force for two
overlapping particles is proportional to the area of overlap of the
two particles, and is thus a non-linear function of overlap distance.
Thus Kn has units of force per area and is thus specified in units of
(pressure). The effects of absolute particle size (monodispersity)
and relative size (polydispersity) are captured in the radii-dependent
pre-factors. When these pre-factors are carried through to the other
terms in the force equation it means that the specified gamma_n is in
units of (1/(time*distance)), Kt is in units of (pressure), and
gamma_t is in units of (1/(time*distance)).< / p >
< p > Note that in the Hookean case, Kn can be thought of as a linear spring
constant with units of force/distance. In the Hertzian case, Kn is
like a non-linear spring constant with units of force/area or
pressure, and as shown in the < a class = "reference internal" href = "#zhang" > < span class = "std std-ref" > (Zhang)< / span > < / a > paper, Kn = 4G /
(3(1-nu)) where nu = the Poisson ratio, G = shear modulus = E /
(2(1+nu)), and E = Young’ s modulus. Similarly, Kt = 4G / (2-nu).
(NOTE: in an earlier version of the manual, we incorrectly stated that
Kt = 8G / (2-nu).)< / p >
< p > Thus in the Hertzian case Kn and Kt can be set to values that
corresponds to properties of the material being modeled. This is also
true in the Hookean case, except that a spring constant must be chosen
that is appropriate for the absolute size of particles in the model.
Since relative particle sizes are not accounted for, the Hookean
styles may not be a suitable model for polydisperse systems.< / p >
< div class = "admonition note" >
< p class = "first admonition-title" > Note< / p >
< p class = "last" > In versions of LAMMPS before 9Jan09, the equation for Hertzian
interactions did not include the sqrt(RiRj/Ri+Rj) term and thus was
not as accurate for polydisperse systems. For monodisperse systems,
sqrt(RiRj/Ri+Rj) is a constant factor that effectively scales all 4
coefficients: Kn, Kt, gamma_n, gamma_t. Thus you can set the values
of these 4 coefficients appropriately in the current code to reproduce
the results of a previous Hertzian monodisperse calculation. For
example, for the common case of a monodisperse system with particles
of diameter 1, all 4 of these coefficients should now be set 2x larger
than they were previously.< / p >
< / div >
< p > Xmu is also specified in the pair_style command and is the upper limit
of the tangential force through the Coulomb criterion Ft = xmu*Fn,
where Ft and Fn are the total tangential and normal force components
in the formulas above. Thus in the Hookean case, the tangential force
between 2 particles grows according to a tangential spring and
dash-pot model until Ft/Fn = xmu and is then held at Ft = Fn*xmu until
the particles lose contact. In the Hertzian case, a similar analogy
holds, though the spring is no longer linear.< / p >
< div class = "admonition note" >
< p class = "first admonition-title" > Note< / p >
< p class = "last" > Normally, xmu should be specified as a fractional value between
0.0 and 1.0, however LAMMPS allows large values (up to 1.0e4) to allow
for modeling of systems which can sustain very large tangential
forces.< / p >
