<div>Dear users,</div>
<div><br>
</div>
<div>I found the origin of the problem. I am doing my calculation on a cluster that has a time limit of 20 hours, but my nscf calculations exceed this time. Since I have 49 K points, I have to use the restart option in the parameter restart_mode, to compute
the last K points not computed during the first 20 hours. However, if I choose a smaller number of K points, for which calculations finish in less than 20 hours, I don't have any problem of different Fermi energies between both orientations. But, if I stop
my calculation with the parameter max_seconds and restart it, then the same problem happens.</div>

<div>Dear users,</div>
<div><br>
</div>
<div>I'm trying to compute the magnetocrystalline anisotropy of C60 on Co with QE 6.3, but I have some troubles doing this. Indeed after an scf magnetic calculation without SOC of this system (with no problem), I use the force theorem to make the nscf calculation
with SOC under two magnetizations : in-plane and out-of-plane. This method works well for the others systems I studied. But in this case, I obtain really different Fermi energies for each magnetization : 3.84eV and 3.63 eV. The DOS are moreorless the same,
except one is translated from the other by 0.2 eV. I've tried a lot of different parameters, playing on the smearing, diagonalization threshold, ... Nothing works. Any idea ?</div>
