< p > Define a computation that returns the coordinates of the vertices
corresponding to the triangle-elements of a mesh created by the < a href = "#id4" > < span class = "problematic" id = "id5" > `fix smd/wall_surface < ls_> `_< / span > < / a > .< / p >
< p > See < a class = "reference external" href = "USER/smd/SMD_LAMMPS_userguide.pdf" > this PDF guide< / a > to using Smooth
Mach Dynamics in LAMMPS.< / p >
< p > < strong > Output info:< / strong > < / p >
< p > 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 < a class = "reference internal" href = "Section_howto.html#howto-15" > < span class = "std std-ref" > How-to discussions, section 6.15< / span > < / a >
for an overview of LAMMPS output options.< / p >
< p > 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.< / p >
< p > It is only meaningful to use this compute for a group of particles
which is created via the < a href = "#id6" > < span class = "problematic" id = "id7" > `fix smd/wall_surface < ls_> `_< / span > < / a > command.< / p >
< p > 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.< / p >
