I am running a 'relax' calculation while using PBEpaw pseudopotentials. After some time the SCF calculations keep running but bfg steps are stuck at the same number 'such as 16'. Also, the value of forces calculated starts oscillating between the same values for coming cycles. <br> I will be highly obliged if anyone can please guide me, about how to resolve this issue and converge the bfg cycle.</div><div dir="ltr" data-setdir="false">Thanks in anticipation</div></div></body></html>
