I am trying to calculate voronoi diagram in 2D by compiling voro++ with lammps. I have two questions.
1) It shows 8 nearest neighbours when a particle should have 6 which is calculated in MATLAB. According to the documentation voro++ can calculate voronoi in 2D when z dimension of the box is in between -0.5 to +0.5 (I use lj units) . Can any one help me why does it show 8 instead of 6?
2) Is it possible to get the indices of the nearest neighbours around a particle?
With best regards,
