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"_ls.
|
|
|
|
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"_ls command.
|
|
|
|
The output of this compute can be used with the dump2vtk_tris tool to generate a VTK representation of the
|
|
smd/wall_surace 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.
