[Pw_forum] Open shell system calculations

[Iryna Zaporozhets]

Dear PW community,

I am working with an open-shell system which requires a lot of
computational efforts. Is it possible to use other options than
spin-polarized calculations (nspin = 2) to reduce computational cost, for
example, restricted open-shell  DFT?  Is there any physical meaning to the
results obtained with spin-unpolarized (nspin = 1) calculations in case of
the open-shell system?

Thank you,
