fix freeze command :h3
|
|
|
|
[Syntax:]
|
|
|
|
fix ID group-ID freeze :pre
|
|
|
|
ID, group-ID are documented in "fix"_fix.html command
|
|
freeze = style name of this fix command :ul
|
|
|
|
[Examples:]
|
|
|
|
fix 2 bottom freeze :pre
|
|
|
|
[Description:]
|
|
|
|
Zero out the force and torque on a granular particle. This is useful
|
|
for preventing certain particles from moving in a simulation.
|
|
|
|
[Restrictions:]
|
|
|
|
Can only be used if LAMMPS was built with the "granular" package. Can
|
|
only be used with atom_style granular.
|
|
|
|
There can only be a single freeze fix defined. This is because other
|
|
parts of the code (pair potentials, thermodynamics, etc) treat frozen
|
|
particles differently and need to be able to reference a single group
|
|
to which this fix is applied.
