compute smd/triangle/mesh/vertices :h3
[Syntax:]
compute ID group-ID smd/triangle/mesh/vertices :pre
ID, group-ID are documented in "compute"_compute.html command
smd/triangle/mesh/vertices = style name of this compute command :ul
[Examples:]
compute 1 all smd/triangle/mesh/vertices :pre
[Description:]
Define a computation that returns the coordinates of the vertices
corresponding to the triangle-elements of a mesh created by the "fix
smd/wall_surface"_fix_smd_wall_surface.html.
See "this PDF guide"_USER/smd/SMD_LAMMPS_userguide.pdf to using Smooth
Mach Dynamics in LAMMPS.
[Output info:]
This compute returns a per-particle vector of vectors, which can be
accessed by any command that uses per-particle values from a compute as
input. See "How-to discussions, section 6.15"_Section_howto.html#howto_15
for an overview of LAMMPS output options.
The per-particle vector has nine entries, (x1/y1/z1), (x2/y2/z2), and
(x3/y3/z3) corresponding to the first, second, and third vertex of
each triangle.
It is only meaningful to use this compute for a group of particles
which is created via the "fix smd/wall_surface"_fix_smd_wall_surface.html command.
The output of this compute can be used with the dump2vtk_tris tool to
generate a VTK representation of the smd/wall_surface mesh for
visualization purposes.
The values will be given in "units"_units.html of distance.
[Restrictions:]
This compute is part of the USER-SMD package. It is only enabled if
LAMMPS was built with that package. See the "Making
LAMMPS"_Section_start.html#start_3 section for more info.
[Related commands:]
"fix smd/move/tri/surf"_fix_smd_move_triangulated_surface.html,
"fix smd/wall_surface"_fix_smd_wall_surface.html
[Default:] none
