Dear LAMMPS developers,
In the latest version (19 May 2017), there is a bug which causes the dump file created using Dump/Local to be empty in certain cases. The attached two-particle simulation reproduces this problem.
I did a bit of investigating to try to help. The bug was introduced in the 2017-02-15 23:45:33 commit (sha1 = 4a80df3a99b87e7fd57e0b49e257918f024d3888) when changes were made to the neighbor lists. The version of LAMMPS immediately before this commit didn’t contain this bug.
In earlier versions of LAMMPS (e.g., 13 Feb 2017), the neighbor lists are created as follows:
in.two_particles_Sandia (978 Bytes)
Two_Particle_Coordinates.lj (486 Bytes)
