<div dir="ltr"><div><div><div><div>Hi everyone,<br><br></div>I am trying to compile wannier90 interface (v2.0.1) with vasp (v5.4.1). I am compiling both vasp & wannier90 with intel MKL libraries. The compilation was successful alright. But when I try to run some calculations the vasp part of calculations goes well but the wannier90 part stops. I am trying to reproduce the process described here: <a href="http://cms.mpi.univie.ac.at/wiki/index.php/Bandstructure_of_Si_in_GW_%28VASP2WANNIER90%29">http://cms.mpi.univie.ac.at/wiki/index.php/Bandstructure_of_Si_in_GW_%28VASP2WANNIER90%29</a> . I am getting the errors at step 3 Let me tell you what I have tried so far.<br><br>First the calculation exited while "Setting up k-point neighbors" & it threw segmentation fault with signal 11. Then I followed this instruction (<a href="http://cms.mpi.univie.ac.at/vasp-forum/viewtopic.php?p=14094&sid=ff743589a8f3dece3c90d09ecd06ad33#p14094">http://cms.mpi.univie.ac.at/vasp-forum/viewtopic.php?p=14094&sid=ff743589a8f3dece3c90d09ecd06ad33#p14094</a>) from vasp forum & removed the optional variables from src/wannier_lib.F90 as instructed.<br><br></div>Now I am getting an error saying " Error: dis_spheres_first_wann is larger than num_bands-num_wann+1
" in wannier90.wout .<br><br></div>I have tried some of the examples from the examples directory of wannier90 with wannier90.x and they seem to be working fine. This issue occurs only when I am trying to use wannier90 interface with vasp. Any clue on how to solve the issue?<br><br></div>I really appreciate your help on this.<br></div><div dir="ltr">-- <br></div><div dir="ltr">Protik Das,<br>ECE Graduate Student,<br>LATTE <span><font color="#888888"><span>(</span><a>http://latte.ece.<span>ucr.edu</span></a><span>)</span></font></span>,<br>University of California, Riverside.</div>
