[gpaw-users] Fwd: Possible error

Hi Isabela

(I am taking the liberty of forwarding this to gpaw-users.)

Yes, the new Mg setup includes an entire shell of extra valence
electrons.  These setups are meant to be accurate but they are
frequently more difficult to converge.  The RMM-DIIS eigensolver is
known not to work so well with the extra shells.  Use the Davidson as
is default in new versions of GPAW.  Or you can switch to the older
setups.  The documentation has been updated with info on how to
specify the old ones:

  https://wiki.fysik.dtu.dk/gpaw/documentation/manual.html#type-of-setup-to-use

Best regards
Ask
