<div dir="ltr"><div>Dear WIEN2K users,<br>I have upgraded wien2k version from 13 to 16 on a 32-core machine. Before this in version 13, I was running using XC-functional option 15(EV-GGA) and I want to run the same XC-functiona in version 16 but its use different format in case.in0 to define XC-functional instead of numerical format. So by referring to SWITCH_LIST.odt in SRC_lapw0, I defined the EV-GGA in my case.in0 as shown below:-<br><br>TOT EX_EV93 EC_PW91 VX_EV93 VC_PW91 (XC_LDA,XC_PBESOL,XC_WC,XC_MBJ,XC_REVTPSS) <br>NR2V IFFT (R2V)<br> 90 30 90 2.00 1 min IFFT-parameters, enhancement factor, iprint<br><br><br></div>But I tried to calculate the total DOS in version 16 using the same structure(case.struct) with the same value of kpoint, rkmax and gmax as I ran before in version 13, I cannot get the same band gaps in version 13. Same goes to my bandstructure.<br><div><br>My questions are<br>1) Is it EV-GGA in option 15 in version 13 same in version 16?<br><br>2) is there any way to use the numerical format to define XC- functional as in version 13?<br><br>I have SEARCHED the archives AND READ THE USERS GUIDE and the FAQ pages, but I couldn't solve my
problem.<br><br><br>Thanks and regards<br><br><br><br><br><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><span style="font-family:verdana,sans-serif">Afiq Radzwan, <br>Doctor of philosophy(Physics) candidate<br>Department of Physics,</span><br><span style="font-family:verdana,sans-serif"><font color="#ff00cc"><font color="#000000">Faculty of Science,<br>Universiti Teknologi Malaysia,<br>81310 UTM Johor Bahru, JOHOR,<br>MALAYSIA.</font></font></span><br><span style="font-family:verdana,sans-serif"><a href="mailto:afiq6@live.utm.my" target="_blank">afiq6@live.utm.my</a> <a href="mailto:afiqradzwan1992@gmail.com" target="_blank">afiqradzwan1992@gmail.com</a><br>+601112108576</span><br></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div>
