[Wannier] Trouble with kmesh/ bvectors

Hello all,

When I run wannier90.x -pp I first got a "kmesh_get: something wrong, found
too many nearest neighbours" error. After looking through the previous
forum discussions I modified kmesh_tol in attempts to fix but now I get
"kmesh_get_bvector: Not enough bvectors found" and when I decrease
kmesh_tol even more I get "Non-symmetric k-point neighbours!". Please help!

Thank you,

Payden Brown

 **WARNING: kmesh has found >12 nearest neighbours**



 This is probably caused by an error in your unit cell specification



 If you think this is not the problem; please send your *.win file to the

 wannier90 developers



 The problem may be caused by having accidentally degenerate shells of

 kpoints. The solution is then to rerun wannier90 specifying the b-vectors

 in each shell.  Give devel_flag=kmesh_degen in the *.win file

 and create a *.kshell file:



 $>   cat hexagonal.kshell

 $>   1 2

 $>   5 6 7 8



 Where each line is a new shell (so num_shells in total)

 The elements are the bvectors labelled according to the following

 list (last column is distance)
