But the value of "nband' at case.inhf is confusing. on the page 97 of UG has mentioned " .... nband should be at least equal to the number of (partially) occupied bands plus one". While at the line 5 of case.in1 the value of nband
is automatically determined ( UG page 102) by " nband = ne ∗ 2.0 + 5 " which is number of eigenvalues. Can we consider inband of case.inhf is equals: (eigenvalues -5)/2+1 which is extracted from case.in1?<br>> > <br>> > <br>> > Best Regards<br>> > Ali<br>> _______________________________________________<br>> Wien mailing list<br>> <a ymailto="mailto:Wien@zeus.theochem.tuwien.ac.at" href="mailto:Wien@zeus.theochem.tuwien.ac.at">Wien@zeus.theochem.tuwien.ac.at</a><br>> http://zeus.theochem.tuwien.ac.at/mailman/listinfo/wien<br>_______________________________________________<br>Wien mailing list<br><a ymailto="mailto:Wien@zeus.theochem.tuwien.ac.at" href="mailto:Wien@zeus.theochem.tuwien.ac.at">Wien@zeus.theochem.tuwien.ac.at</a><br><a href="http://zeus.theochem.tuwien.ac.at/mailman/listinfo/wien" target="_blank">http://zeus.theochem.tuwien.ac.at/mailman/listinfo/wien</a><br><br><br> </div>
