Describe the bug
The
$ffnb
section doesn't make sense during GFN-FF optimization. I followed the guide in the Manual neighbor list setup, but the atom 2 and 8 still exist in neighbor list of atom 1.To Reproduce
Running with xTB-6.7.1.
The input files
La-Complex.xyz
andxcontrol
are copied from the document.La-Complex.xyz
xcontrol
and execute
xtb La-complex.xyz --gfnff --input xcontrol --wrtopo nb --opt
.In the output, the atom 2 and atom 8 still connected to atom 1. In the
gfnff_list.json
, they are still in neighbor list of atom 1.gfnff_lists.json
The verbose output are uploaded
verbose.log
, there is a warning:Expected behaviour
The atom 2 and 8 dissociating during optimization.
