Respected Users,<br>
<br>
Would you like to tell me what automatic (like 48 48 1)<br>
the dense k-point grid in the first scf calculations<br>
(i.e. scf-fit). I should use<br>
to get <span class="q">special q point<br>><br>> 0.6666667 0.0 0.0<br>>as a </span>the subsets of the scf-fit ????<br>
Is there any definite rule except applying a trial and <br>
error method like 4 4 1, 6 6 1, 9 9 1, 38 38 1 etc. etc. ????<br>
Your kind help will be greatly appreciated.<br>
Regards,<br>
