<div dir="ltr"><div><div>Dear All<br></div>I am performing structural relaxation for Si (100) with H at its top and bottom (structure is attached, vacuum is 12 A). I have inspect the mailing list in detail (like <a href="http://www.wien2k.at/reg_user/textbooks/DFT_and_LAPW_2nd.pdf">http://www.wien2k.at/reg_user/textbooks/DFT_and_LAPW_2nd.pdf</a> AND <a href="http://www.mail-archive.com/search?q=core+leakage&l=wien%40zeus.theochem.tuwien.ac.at">http://www.mail-archive.com/search?q=core+leakage&l=wien%40zeus.theochem.tuwien.ac.at</a>) and have resolved the issue by selecting SE -12, but the calculation hang out after LAPW0. Inspection of lapw1_1.error message is "Error in LAPW1". Please suggest me the possible solution.<br><br></div><div>One more thing I found in the list "<pre>If
you have core leakage, inspect in case.outputst whether you can take
some high-lying core states as valence states instead</pre>"<br></div><div>Is it possible to make it manually with same SE ? or simple done by lowering down SE as I did?<br><br></div><div>Many thanks <br><br></div></div>
