<div>Hi!</div>
<div> </div>
<div> i have a question about bands calculation .</div>
<div> Just after finished a '<strong>scf</strong>' calculation for tio2, i performed a series (about 5) '<strong>nscf</strong>' calculations with different k-grid paths. Except k-grid path, all settings are the same for these series ' nscf ' calculation.
</div>
<div>In some nscf-output, the values of "Highest occupied level and lowest unoccuped level" are found. But these values are not found in the other nscf-output . I donot know what the reasons are related to . Morever, i also came to a calculation failed with complains "Too many eigenvalues are not converged".
</div>
<div> </div>
<div>Regards,</div>
