[Pw_forum] projwfc.x cannot produce the correct Lowdin charges or fail completely

2014-10-03 Thread Li, Run
Dear all, I tried to use projwfc.x to produce PDOS and lowdin charges. Two of my systems run into different problems while the others seemed okay. Could you please help me figure out what is going on? 1. A 73 atom molecule Zn(II) Phthalocyanine tetrasulfonic acid in 3D cell. PBE-D

Dear all, I run into some problem trying to visualize the STM image with Xcrysden. I followed the hands-on tutorial (http://www.fisica.uniud.it/~giannozz/QE-Tutorial/tutorial_postproc.pdf), used pp.x to generate STM. However, I couldn't visualize the generated output AlAs110-1.0.xsf as the

Hi all, I'm trying to calculate the DOS of graphene, but no matter what functional and pseudopotential I use, I keep getting DOS=0 about 1.4eV around Fermi level , even though the bands calculation can get the Dirac point at K point, showing the conduction band is touching the valence bands,

[Pw_forum] PW relax cannot move atoms

2013-12-10 Thread Li, Run
Hello, I have a questions about relax and vc-relax using pw.x. I tried to use them to optimize the geometry of graphite, and the atoms can barely move even though I move them manually I can get lower energy. I'm not sure why. For example, I take 7 layers of ABAB stacked grapheme, fix the
