<html><head></head><body><p>Dear All,</p><p>In Vasp there is two options
for doing spin polarized computations : ISPIN=2 which is done without any
restriction. And ISPIN=2 and NUPDOWAN=2 or 4. In the later casse the spin
polarized caculation is done with imposing restriction on the number of
alpha and beta electrons. I wish two konw what are the equivalent
cases for spin polarized calculation in PWSCF
