Dear Gabriele,<br><br>i`m new to PW code and i wanted to know how LDA+U works with a non-magnetic calculation.<br>Basically how the term U is treated in non-magnetic calculation.<br>i used "mean-field" as LDA+u is a mean-field solution.<br>

So your question is not much clear to me...<br>
<br>
PWscf implements standard DFT with the usual approximations to the XC functional (LDA,<br>
GGA,...)<br>
<br>
Or are you maybe referring to AMF (around-mean-field) for double counting in LDA+U?<br>
<br>
