<p dir="ltr">If :DIS, :ENE, :MV etc are converged, the energy is reliable within the accuracy of your choice of functional.</p>

<div dir="ltr">Hi,
<div>I found the following message in the scf file. I searched the mailinglist and found a thread about it. Is there any reasonw why PWs would automatically change? I put the total energy below. Is the total energy reliable? The first time when the warning
showed up, the total energy changed a lot. Then, total energy gradually converges to -29570.82940380. At one iteration, the warning disppeared. Then, the warning occurred again. But the total energy did not change much. </div>
