<p>So many things wrong:<br>
1. Why are you hiding what the atoms are? We have many other things to do, we are not going to steal your structure.<br>
2. Atoms close to 1/3, 1/2 & 2/3 ? Probably they should be at the fractions for the right symmetry.<br>
3. RMT 2? Did you ignore setrmt ?<br>
4. For k-pts the density in reciprocal space matters, so 9x9x3 is wrong. 3x3x3 is perhaps, but as mentioned above since you are hiding details nobody except you can decide.<br>
5. For a 20 atom low symmetry structure it will be slow. To improve the speed you need to improve the physical model. Have you worked through the examples for TiC and others to learn first?</p>

<br>
<div>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>
