Dear Jibiao Li,
<div class=""><br class="">
</div>
<div class="">Your unit cell is too small, when ESM is activated the cell goes from -c/2 to c/2, which in your case is approximately -7 Bohr to 7 Bohr if I am not mistaken.</div>
<div class=""><br class="">
</div>
<div class="">You should also have a look at your k-points (c axis), I think you will also get an error about that.</div>
<div class=""><br class="">
<div class="">
<div>Best regards,</div>
<div>Tom Demeyere</div>
