[lammps-users] the sequencing of atoms in dump file is different with that in the data file

Dear all,

Why the sequencing of atoms in dump file is different with that in the data file? I mean the third row in the following data is different in two files. For example: the data file:

1 0 1 .050 36.898 14.643

2 0 1 .994 39.444 16.253

3 0 1 .042 36.901 11.436

4 0 1 1.010 39.446 13.036

5 0 1 .032 36.902 8.242

6 0 1 1.001 39.448 9.837

7 0 1 -.014 36.897 5.048

8 0 2 .990 39.449 6.643

9 0 2 -.019 36.896 1.850

10 0 2 .978 39.450 3.452

11 0 2 1.255 39.094 .561

The dump file:

1 0 1 3.755 39.379 14.661

2 0 1 2.766 36.795 9.866

3 0 2 3.750 39.382 11.458

4 0 2 2.756 36.796 6.674

5 0 2 3.740 39.383 8.266

6 0 1 2.741 36.793 3.482

7 0 1 3.729 39.382 5.074

8 0 1 2.737 36.782 .289

9 0 2 3.719 39.382 1.883

10 0 1 5.535 36.806 14.658

11 0 1 1.255 39.094 .561

I will appreciate it if you could give me some suggestions.

Best wishes,

Xiaojing
