compute smd/triangle/vertices command
compute ID group-ID smd/triangle/vertices
ID, group-ID are documented in compute command
smd/triangle/vertices = style name of this compute command
compute 1 all smd/triangle/mesh/vertices
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.
See this PDF guide to using Smooth Mach Dynamics in LAMMPS.
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 the Howto output doc page 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 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 of distance.
This compute is part of the USER-SMD package. It is only enabled if LAMMPS was built with that package. See the Build package doc page for more info.
