[QE-users] Appropriate wavefunction cutoff

2021-02-10 Thread Hadibandhu Moharana
Hello, I am trying to study a system consisting of Li,Cl and O. I am using pseudopotentials of PAW(pbe) type for Li,Cl and O with suggest minimum wavefunction cutoffs 78Ry, 36Ry and 47Ry respectively. From the literatures , it is clear that everyone is using cutoff less than 50

[QE-users] vc-relax and temperature

Hello, I finally turned to CP2K to use PBE0-D3. The equivalent of vc-relax worked for my molecular crystal and the structure converged. I did an all-electron simulation and have not yet used pseudopotentials. So I really wonder what's wrong with QE, concerning the same simulation using hybrid

Dear All, I am getting following error in occupation factor calculation using epsilon.x of QE-6.4.1 for metals. In post-processing user guide it is recommended that to calculate occupation factor first for metallic systems. The error message and input files are,

[QE-users] bad band number error in epsilon calculation

2021-02-10 Thread hamed asadi
Dear QE experts; I am trying to run epsilon.x for doped graphene but I have no idea about how to solve the "bad band number error". I changed the nbnd values and the pseudopotential type and the kpoint values to automatic and tpiba, but I still see the same error. I have included the input files be
