[Pw_forum] eigenvectors failed to converge in development pw.x

2015-04-09 Thread Peter Scherpelz
Hi, I encountered a strange error that I wanted to report in case it affects current development, in which an scf calculation fails in the nightly development (#19173) but succeeds in 5.1.2. Both are compiled on a multi-core linux desktop. When noncollinear calculation is specified, and a potenti

Dear All I want to know that is there any website to have WC pseudopotentials (PAW or Ultrasoft) except for PSLibrary of THEOS? Regards Mojtaba Mirseraji Ph.D. Candidate Theoretical Condensed Matter Physics Arak Univ. I.R.IRAN ___ Pw_forum mailing list

Dear All I want to run some jobs (like that scf.in, scf2.in, scf3.in and ...) subsequently and without wasting the time. How to do it? which command should I write? e.g. : mpiexec -n 8 ./pw.x scf1.out ; mpiexec -n 8 ./pw.x scf2.out ; mpiexec -n 8 ./pw.x scf3.out ; mpiexec -n 8 ./pw.x scf4.out

Dear All When I relax BaTiO3 by WC Pseudopotentials of THEOS (PSLibrary), I have the problem of "diagonalization (ZHEGV*) failed". (Espresso 4.3.2) help me please Relax input file: &CONTROL calculation = 'relax' , restart_mode = 'from_scratch' ,

Dear All How to optimize the BaTiO3 tetragonal structure? Because when I use minimum energy and zero pressure, I face to very different lattice parameters (celldm(1) and celldm(3)) in comparison to experiment and even DFT calculations!!! I used PZ/PW91/PBE/PBESOL but all of them were different

Dear Éric Germaneau, I use TB09 to calculate the gap of black phosphorus. I read some paper of using mBJ and they showed good results in agreement with experimental results. They used PAW with mBj using VASP soferware, thus, I want to make it come true in QE. Truely PL Gong >

Dear Juliana, there is at least a partial implementation of stress calculations but I am not sure if it has been ever tested properly. Cheers Layla 2015-04-08 20:48 UTC+02:00, Juliana Morbec : > Dear All. > > I would like to know, please, if hybrid functionals (HSE or PBE0) are > implemented in

Some PP will work some won't. Do everything go well using other GGA or LDA functionals? What do you want to use TB09 for ? and Why? It's very tricky to use it you know. On 04/09/2015 02:46 PM, plgong wrote: Dear Éric Germaneau, I used your input file (Si.pbe-rrkj.UPF) to do a test, but it r
