</span>This is a standard PBE calculation:<br>
:POT : POTENTIAL OPTION EX_PBE EC_PBE VX_PBE VC_PBEfor all the cycles.<br>
In fact the surprising thing was that this started out of the blue<br>
after at least 15 iterations when the calculation was already looking<br>
quite converged.<br>
<br>
BTW as mentioned in the beginning this might have to do something with<br>
the atomic spheres, I converged this structure with the almost touching<br>
spheres (0% reduction) and later I did reduce_rmt_lapw -r 3.5 to<br>
produce this case, hence it was already pre-converged and I only wanted<br>
to fine-converge it, however the energy oscillations showed...<br>
Dunno of this might play a role.<br>
