<br>
We are doing surface calculations using dipole correction.<br>
The system under consideration is Cu(111) plane and we have considered 4 atomic layers. I am attaching the input files with this mail. <br>
<br>
I have noticed that, for 3x3x1 unshifted k-point mesh, I get 3 k-points with no dipole correction and 5 k-points with dipole correction. <br>
<br>
I am unable to understand how dipole flag changes the number of k-points. Could you please shade some light on this? <br>
<br>
Thanks,<br>
