[DFTB-Plus-User] Failure in diagonalisation routine ZHEEVR for Li-S systems

Dear Qisheng Wu,
what I meant is, that if you generate the parametrization yourself, you
have control over the extent of the atomic orbitals via the wave
function compression radius. Setting it to a low value, will compress
the atomic orbitals and decrease their extent, while a high value
results in more delocalized atomic orbitals. Setting the wave function
compression radius for Li higher (compressing it less) may make the
diagonalization of closely packed LiS structures more robust.
Best regards,
Bálint
