Without more information nobody is going to be able to help you as we have no idea what your structure is, your RMTs, your cell size, your computer speed, cores...and more. Probably you have these incorrect, but I am just guessing. For certain, whenever I see "-c" I start to suspect that the calculation has been incorrectly setup.<br>

<div>When I did the calculation of the interfical energy, I cannot tolerate the time-consuming process of the SCF.</div>
<div>It took 14 hours to finish just one iteration, and there was over 90 iterations. My god!</div>
<div><br>
</div>
<div>I want to know, if there are some keys in the setting to do the calculation of the interfacial energy? My setting is normal</div>
<div> and almost accept all the recommendations which wien2k giving in every step. And the k-mesh is settted as 9*9*3, the model</div>
<div>of the interface is 2 layers, just like AA|BB, without vacuum layer.</div>
<div>The part of dayfile is as follows.</div>
