Thank you so much!<br>
<br>
Unfortunately fs.x continues to crash with the errors<br>
<br>
Error in routine fill_fs_grid (1):<br>
cannot locate k point<br>
<br>
<br>
in the .out file,<br>
<br>
and<br>
<br>
task # 15<br>
from fill_fs_grid : error # 1<br>
cannot locate k point<br>
<br>
in the CRASH file.<br>
<br>
<br>
I can see that in the .xml file the k points are written inside <br>
the <band_structure> block.<br>
<br>
<br>
Can you address me in understanding where fs.x expects to find the <br>
k points but it does not find them, please?<br>
<br>
<br>
I also attach the bash script I submit, maybe I'm doing something <br>
wrong at this level...<br>
<br>
<br>
A marginal question, in the .out file I see a Fermi energy ~ 7.2 <br>
eV but in the .xml file I see a Fermi energy of ~ 2.6e-1. If the <br>
latter is in Ry, corresponds to ~ 3.6 eV rather than 7.2 eV... is this <br>
however fine?<br>
<br>
<br>
Thanks in advance for your support,<br>
<br>
