21 fix 1 all nve/asphere :pre
25 Perform constant NVE integration to update position, velocity,
26 orientation, and angular velocity for aspherical particles in the
27 group each timestep. V is volume; E is energy. This creates a system
28 trajectory consistent with the microcanonical ensemble.
30 This fix differs from the "fix nve"_fix_nve.html command, which
31 assumes point particles and only updates their position and velocity.
33 [Restart, fix_modify, output, run start/stop, minimize info:]
35 No information about this fix is written to "binary restart
36 files"_restart.html. None of the "fix_modify"_fix_modify.html options
37 are relevant to this fix. No global or per-atom quantities are stored
38 by this fix for access by various "output
39 commands"_Section_howto.html#howto_15. No parameter of this fix can
40 be used with the {start/stop} keywords of the "run"_run.html command.
41 This fix is not invoked during "energy minimization"_minimize.html.
45 Styles with a {gpu}, {intel}, {kk}, {omp}, or {opt} suffix are
46 functionally the same as the corresponding style without the suffix.
47 They have been optimized to run faster, depending on your available
48 hardware, as discussed in "Section 5"_Section_accelerate.html
49 of the manual. The accelerated styles take the same arguments and
50 should produce the same results, except for round-off and precision
53 These accelerated styles are part of the GPU, USER-INTEL, KOKKOS,
54 USER-OMP and OPT packages, respectively. They are only enabled if
55 LAMMPS was built with those packages. See the "Making
56 LAMMPS"_Section_start.html#start_3 section for more info.
58 You can specify the accelerated styles explicitly in your input script
59 by including their suffix, or you can use the "-suffix command-line
60 switch"_Section_start.html#start_7 when you invoke LAMMPS, or you can
61 use the "suffix"_suffix.html command in your input script.
63 See "Section 5"_Section_accelerate.html of the manual for
64 more instructions on how to use the accelerated styles effectively.
70 This fix is part of the ASPHERE package. It is only enabled if LAMMPS
71 was built with that package. See the "Making
72 LAMMPS"_Section_start.html#start_3 section for more info.
74 This fix requires that atoms store torque and angular momementum and a
75 quaternion as defined by the "atom_style ellipsoid"_atom_style.html
78 All particles in the group must be finite-size. They cannot be point
79 particles, but they can be aspherical or spherical as defined by their
