[DFTB-Plus-User] Ionic relaxation

Dear Summayya Kouser,

You should set "d" for the maximal anguler momentum of S. You can find
out the shells for a given atom by searching for the word Shell in the
corresponding homonuclear SK-file, e.g.

grep Shells S-S.skf

would give you

<Shells>3s 3p 3d</Shells>

The maximal angular momentum is not really a parameter you can tune or
change, but must be set exactly according to the documented value in the
SK-files. It is only due to historical reasons, that it appears in the
user input...

Best regards,

  Bálint
