[Wien] A Strange DOS Problem

[jingyun_1984@sohu.com]

Dear Wien users and developers!<p>I want to calculate and plot the<p>DOS at ambient and high pressure <p>of my case，which is fcc structure.<p><p>I am running the scf cycle with <p>runsp_lapw (no extra<p>switches). XC-potential: 'GGA<p> of Perdew-Burke-Ernzerhof 96'<p> size of k-mesh: 1000 k-points.<p><p>I can initialize my case and run <p>it to self-consistency without getting<p>any warnings or error messages.<p> I have succeeded in plotting the DOS<p> at ambient pressure. When I decrease <p>the lattice constant (increasing the pressure)<p> a bit, everything is 0k. But when I continue <p>to decrease the lattice constant, the DOS is <p>zero everywhere and the top energy is -8.0eV, <p>which is far away from the Fermi energy. <p>I have tried to increase the Emax in case.in1, <p>which does not work out. I wonder why?<p><p>Thanks for your replies!<p><p>Any suggestions are welcome! Please let me know<p>t if you need more<p>information from me to understand this problem.<p>Best re!
 gards,<p>Jingyun Zhang <p>
